    Host your PDF anywhere — Google Drive (use the "anyone with link" share URL), Dropbox, your own server, S3, etc. Paste the public link here. We encode the URL so the QR works forever and never depends on us. Tip: for Google Drive, replace /view in the share URL with /preview for a cleaner mobile view.

    Enhver fil, der kan downloades — installationsprogram, arkiv, dokument, datasæt. Host det hvor som helst; vi koder URL'en. Brugerens browser håndterer downloaden efter sine egne MIME-type-regler.

    JPEG, PNG, WebP, GIF eller HEIC — host det hvor som helst. Mobilbrowsere åbner billedet i fuld skærm; desktopbrowsere viser det integreret.

    YouTube- og Vimeo-URL'er åbnes native i deres apps på telefoner. Direkte .mp4-/.webm-filer åbnes integreret i alle moderne browsere.

    MP3 / OGG / WAV / FLAC / M4A direct URLs play inline in mobile browsers. Spotify (open.spotify.com/track/…) and SoundCloud (soundcloud.com/…) URLs open in their apps. Apple Music / Bandcamp / Tidal links also work.

    Restaurant / cafe / bar menu — point to a PDF, an HTML menu page, or your online-ordering platform (Toast / Square / DoorDash / Uber Eats). Print on table tents, host signs, or window stickers. Pro tip: use a frame ("Scan our menu") so customers know what to do.

    Paste your form's share link — either the short forms.gle/… or the long docs.google.com/forms/d/e/…/viewform form. We auto-prefer forms.gle when both are available since the shorter URL produces a denser QR. Works for surveys, registrations, RSVPs, lead capture, classroom polls.

    Et rødt schweizisk flag overlejres automatisk på QR-koden — påkrævet af schweiziske banker.

    Avanceret tuning

    Indsæt en BOLT11-faktura (lnbc...) eller en Lightning-adresse. Vi tilføjer præfikset lightning: URI-schemaet, så enhver Lightning-pung kan scanne den.

    Use this if you're enrolling a new 2FA account in an authenticator app (Google Authenticator, Authy, 1Password, Bitwarden). Do not screenshot, email, or photograph this QR — the secret inside it is a permanent key to the account.

    Avanceret tuning

    Kompatibel med Google Authenticator, Authy, 1Password, Bitwarden og enhver standard TOTP-app.

    Use this if you're provisioning a counter-based hardware token (YubiKey OTP) or a system without a reliable clock. Do not use when TOTP will do — HOTP counters drift, and recovery is harder after a dropped sync.

    Avanceret tuning

    HOTP (RFC 4226) is the counter-based sibling of TOTP. Use it for hardware tokens like YubiKey OTP or for systems without reliable clocks. Same otpauth:// scheme; counter increments per code instead of advancing on time.

    Use this if you're a carrier or MVNO issuing an eSIM activation profile to a customer (iOS 17.4+ / Android 13+). Do not share this QR after it's been scanned — the SM-DP+ activation is usually single-use and the profile belongs to one device.

    GSMA SGP.22 aktiveringskode iflg. LPA. iOS 17.4+ og Android 13+ scanner dem direkte til at provisionere eSIM-profiler.

    Per RFC 3261, opens a SIP softphone (Linphone, Zoiper, Bria, etc.) and dials the address. sips: forces TLS for signalling. Works with Asterisk, FreeSWITCH, 3CX, and any standards-compliant PBX.

    Opens the system MMS composer to send a multimedia message (text + image/audio/video attachment). Distinct from sms: in that the recipient receives an MMS-formatted message. iOS, Android and most carrier apps honour this scheme.

    Paste the QR URL from your Alipay Receive Money page (Settings → My QR Code → Save). We pass it through verbatim. The Alipay app, AliPayHK, and any device with the Alipay+ scanner will recognise the URL or QR.

    Personal receive codes start with wxp://f2f. Merchant codes are https://payapp.weixin.qq.com/... URLs from the Weixin Pay merchant portal. Paste either; we encode verbatim. The WeChat app and any Weixin-Pay-enabled scanner will resolve it.

    Swish is Sweden's national P2P / merchant mobile-payment service. Payee can be a private mobile number (Swish-number) or a 1234-style merchant alias. The Swish app on iOS and Android scans the standard swish://payment?data=... URI.

    Vipps is Norway's dominant mobile-payment app (now Vipps MobilePay across the Nordics). Send to phone emits a vipps://send?... deeplink for P2P; Merchant short-link wraps a https://qr.vipps.no/... URL.

    Paste the link from your Mercado Pago Cobrar page (the https://mpago.la/..., https://link.mercadopago.com.br/..., or full mercadopago.com short-link). Works across MP apps in Argentina, Brazil, Mexico, Chile, Colombia, Uruguay and Peru.

    Use this if you need pharma / medical / direct-part-marking symbology or you're encoding for industrial imagers. Do not use for consumer-facing signage — Apple iPhone cameras do not decode Data Matrix natively.

    Data Matrix is a square 2D matrix barcode (ISO/IEC 16022) used in healthcare, electronics, manufacturing, and direct-part marking. Holds up to ~2,335 alphanumeric characters in a single tag. Note: this is not a QR code — QR-only styling (eyes, dots, gradients, frames, logos) is disabled and the basic monochrome render is used.

    Use this if you're generating boarding passes, transit tickets, or electronic-ID payloads for dedicated scanners. Do not use for public marketing print — most phone cameras won't decode Aztec reliably.

    Avanceret tuning

    Aztec Code (ISO/IEC 24778) is the 2D barcode used by airline boarding passes, train tickets, and electronic ID. Designed to scan well on phone screens and at low contrast. Holds up to ~3,067 alphanumeric characters. Not a QR; QR-only styling is disabled.

    Use this if you're printing an IATA-compliant boarding pass (Aztec, QR, or PDF417) for gate scanners at any of the 200+ airlines that implement BCBP / Resolution 792. Do not use this to board a real flight you didn't check in for — the format carries no cryptographic signature; airline gate systems validate against their own DCS, not against the QR itself.

    Advanced — paste raw BCBP string

    If your airline or PSS (Amadeus / Sabre / Navitaire / HP Shares) already exports a full BCBP string, paste it here to preserve conditional fields, multi-leg data, and security sections the structured form doesn't expose.

    IATA Resolution 792 / BCBP Implementation Guide v7. Encode as Aztec for mobile boarding passes, PDF417 for printed Type-A stock, or QR for modern gates. We build the mandatory M1 header + a single leg; paste the full BCBP in Advanced for multi-leg itineraries.

    Use this if you need stacked-linear barcode for driver's-licence parsing, boarding passes, airbills, or AAMVA workflows. Do not use for normal consumer phone-camera signage — coverage is uneven across readers.

    Avanceret tuning

    PDF417 (ISO/IEC 15438) is a stacked linear barcode used on US driver's licences, passports, FedEx airbills, and AAMVA-encoded ID cards. Holds up to ~1,800 ASCII characters. Not a QR; QR-only styling is disabled.

    Use for legitimate purposes only: AAMVA parser testing, kiosk & age-gate development, accessibility tools, and demoing AAMVA workflows. Producing a counterfeit government ID is identity fraud and is prosecuted as a felony in every US state. Use real data only when you own the source license, or use synthetic data clearly marked as such.

    Code 128 (ISO/IEC 15417). Variabel længde, høj densitet, koder hele ASCII-sættet. Bruges på fragtetiketter (UPS, FedEx, DHL bruger det til intern sporing), forsyningskæde og industriel mærkning.

    Code 39 (ISO/IEC 16388). Den originale alfanumeriske stregkode, understøttet af alle scannere nogensinde fremstillet. Bruges på patientarmbånd i sundhedsvæsenet, militærlogistik (LOGMARS) og lagermærkning.

    Code 93 — Symbol Technologies' mere kompakte efterfølger til Code 39. Obligatoriske to kontrolsumtegn (C og K) gør den mere pålidelig på slidte etiketter.

    Codabar (NW-7) — bruges af blodbanker i USA, FedEx-luftfragtsedler (legacy), biblioteker (USA/CA/EU) og fremkaldelse af fotos. Selvkontrollerende; kræver ikke et kontrolciffer.

    EAN-13 / GTIN-13 — globalt detailhandelsproduktidentifikator. Bruges uden for Nordamerika (som bruger UPC-A) på alle forbrugerprodukter. Brug det 12-cifrede GS1-nummer; det 13. kontrolciffer beregnes for dig.

    EAN-8 / GTIN-8 — kompakt detailhandelsproduktidentifikator til små emballager, hvor EAN-13 ikke passer (tyggegummi, batterier osv.).

    UPC-A / GTIN-12 — nordamerikansk detailhandelsproduktidentifikator. Brug det 11-cifrede GS1-nummer.

    UPC-E — kompakt 8-cifret nulkomprimeret variant af UPC-A til små emballager.

    ITF-14 (Interleaved 2 of 5) — GS1s standard for fragtkasser/ydrekasser. Identificerer produktet indeni (GTIN-14). Bruges af alle store detailhandlere og 3PL-lagre.

    Køretøjsidentifikationsnummer per ISO 3779. Kodet som en Code 39-stregkode for kompatibilitet med statslige DMV-scannere, bilregistre og forsikrings-/ejendomsretsarbejdsgange. Det 9. tegn er et kontrolciffer (auto-valideret, ikke auto-beregnet — ugyldige VIN-input kodes stadig til testformål).

    Paste the link from your Payconiq merchant portal — typically https://payconiq.com/t/1/... for transactions or https://payconiq.com/l/1/... for static merchant QRs. Scanned by Payconiq, Bancontact, KBC Mobile, Belfius, ING, BNP Paribas Fortis, and most Benelux banking apps.

    EPC QR Code (EPC069-12 / Girocode) — the European standard for SEPA Credit Transfer initiation via QR. Supported by most European banking apps including Sparkasse, ING, KBC, BNP Paribas, Rabobank, and all EPC-compliant banks.

    Paste the URL to your .pkpass file or Apple Wallet deep link. Scanning opens the pass directly in Apple Wallet on iOS devices.

    Paste the Google Wallet save link from the Google Pay API or your pass issuer. Scanning opens the pass directly in Google Wallet on Android devices.

    Indkoder hele authorized_keys-linjen. Scan for at kopiere/indsætte nøglen på en ny maskine.

    For meget lange nøgler skal du bruge rMQR landskab eller opdele i flere QR-koder. Standard QR har en grænse på ca. 2 KB.

    De officielle WireGuard-mobilapps scanner disse direkte. Medtag aldrig din private nøgle i en printet QR — kun digital deling.

    Use this if your WebAuthn server issued a FIDO:/ URI for cross-device passkey sign-in, or if you want a QR that opens your passkey-management page. Do not use this to "create" a passkey — the URI is issued by your relying party; we only wrap it as a QR.

    The FIDO:/ URI is generated by your relying party (the site you're signing into) and is session-specific — it embeds a short-term session key plus a long-term identity key. Paste it here and we wrap it as a QR. Apple Safari, Chrome, Edge, and 1Password all recognise the FIDO:/ scheme for CTAP 2.2 hybrid transport.

    Use this if your healthcare provider, state health department, or health-wallet app gave you a shc:/ URI (vaccination record, lab result, discharge summary, prescription) and you want to share it as a QR code. Do not use this to "create" a health card — the cryptographic signature is issued by the health authority; we only wrap the URI as a QR.

    The URI starts with shc:/ followed by digits. If your card is chunked (shc:/1/2/..., shc:/2/2/...), paste one chunk at a time and generate one QR per chunk — SHC verifiers scan them in sequence. Single-chunk payloads fit in a V22 QR (~1,191 digits).

    Use this if you're a brand owner preparing for the GS1 Sunrise 2027 cutover or you need a single code that carries product identity + batch/expiry/serial. Do not use as a standalone marketing QR — retailers' POS systems will treat it as inventory data first, URL second.

    GS1 Digital Link er det moderne, webvenlige alternativ til EAN-13-stregkoden for detailprodukter. Resolver-domænet er som standard id.gs1.org, men du kan bruge dit eget.

    Use this if you're a manufacturer or importer preparing for the EU Digital Product Passport (DPP) mandate, operational 19 July 2026 under ESPR Regulation (EU) 2024/1781. Each individual product instance sold in the EU needs a scannable QR or Data Matrix resolving to its DPP record. Do not use this as a marketing QR — the URL should resolve to structured DPP data (JSON-LD), not a landing page.

    Flere felter (valgfri)

    The QR encodes a GS1 Digital Link URL pointing to your DPP record — the same URI syntax as GS1 Digital Link (Article 10 mandate explicitly references it). Your resolver must return structured DPP data (GS1 Digital Link resolver or custom JSON-LD endpoint) and the unique identifier must comply with ISO/IEC 15459:2015.

    Indsæt delingslinket fra Spotify-appen, eller kun id'et. Vi bygger open.spotify.com-URL'en automatisk.

    Formatet afhænger af platformen — for Mastodon brug @bruger@instans, for Bluesky brug handle.bsky.social, for Nostr indsæt npub-nøglen.

    Geo URI (RFC 5870) åbner direkte i enhver kortapp på enheden — Google Maps, Apple Maps, OsmAnd osv. — uden at vælge en leverandør.

    Standard BitTorrent magnet-link. Scannes af enhver BitTorrent-klient, der understøtter URI-schema-handlers.

    The slug in your Yelp URL after /biz/. Scanning opens the Yelp Write A Review page.

    The d + numeric ID from your TripAdvisor listing URL. Scanning opens the Write Review page.

    Routes happy customers to your public review page and unhappy ones to a private channel. The branching happens in the user's browser via a hash splash at /review/ — no backend, no tracking. Important: Google's review-gating policies prohibit hiding negative reviews — use this only to collect private feedback in addition to allowing all customers to leave a public review if they choose.

    Tries the deep link first; if the app isn't installed, shows the right store button (App Store on iOS, Play Store on Android). On desktop, opens the web fallback. OS detection happens at /app/ — no backend.

    Paste any meeting invite link. For Zoom, Google Meet, and Teams we extract the canonical join URL automatically.

    If a URL is provided, the QR opens the page with your promo code appended as ?code=YOURCODE. Without a URL, the QR encodes the plain promo code text.

    PayShap — BankservAfrica's real-time rapid payment rail, live across every major South African bank (Absa, FNB, Nedbank, Standard Bank, Capitec, Discovery, Investec, TymeBank). Send in <10 seconds by mobile number or ShapID.

    Use this if you want to share your Zelle-registered email or US phone number as a scannable contact card. Note: Zelle has no universal QR URI scheme — scanners open your chosen contact method; the payer still initiates the transfer from their own banking app. This QR is a convenience, not a direct-pay link.

    Zelle is built into every major US bank app (Chase, Bank of America, Wells Fargo, Capital One, Citi, and ~2,000 others). This QR encodes a mailto: or tel: that opens the recipient's contact card. The payer then opens their banking app, taps Zelle, and pastes the email / phone — the actual transfer happens bank-to-bank, never through us.

    Satispay — Italy's licensed payment-institution mobile wallet. Accepted by 300,000+ Italian merchants. Customers scan the QR from the Satispay app; no card data, no typing PIN.

    Use this if you're piloting Drex (Brazil's wholesale/retail CBDC, launched 2026 by Banco Central do Brasil on a Hyperledger Besu DLT). Drex settles via the existing Pix infrastructure; most merchant integrations accept the same Pix EMVCo-style QR with a Drex flag.

    Drex — Brazil's tokenised central bank digital currency, Phase-1 live 2026. Settles through existing Pix QR infrastructure during the transition. For pure-Pix transfers, use Pix.

    Use this if you're testing Digital Euro pilot rails (ECB preparation phase, 2023–present; live retail issuance decision expected late 2026). Format follows EPC / SCT-Inst QR patterns with a CBDC flag. Not yet a production payment method — pilot participants only.

    Digital Euro — the ECB's proposed retail CBDC. Preparation phase runs through Oct 2026; live issuance pending Governing Council decision. For standard euro bank transfers, use SEPA or EPC Girocode.

    Digital Ruble — Bank of Russia CBDC. Pilot banks began retail rollout September 2026; mandatory distribution via commercial banks scheduled phase-in through 2027. Each wallet address is issued by a participating bank.

    e₹ / Digital Rupee — the RBI's retail CBDC, live via pilot banks since December 2022. QRs share UPI-style VPAs with an @{bank}digital suffix (e.g. @icicidigital, @hdfcdigital). Interoperable with the existing UPI QR landscape since October 2023.

    Use this if you want a reusable Lightning receive QR. BOLT12 offers (lno1...) don't expire and can be scanned repeatedly, unlike BOLT11 invoices. Not all Lightning wallets support BOLT12 yet (Phoenix, Core Lightning, LNDk, Zeus partial); check your wallet before handing out printed QRs.

    BOLT12 "offers" are the reusable successor to BOLT11 Lightning invoices — no per-payment re-issuance, no 1-hour expiry. Generated server-side by Core Lightning (lightning-cli offer), LNDk, or Strike. Our QR is a passthrough.

    Monero (XMR) is the largest privacy-by-default cryptocurrency. QR emits a monero: URI per the community-standard scheme; GUI and CLI wallets, Cake, MyMonero, Feather, and Monerujo all parse it.

    Use this if you're printing the onboarding QR for a Matter-certified smart-home device (light bulb, sensor, lock, thermostat). The code admits the device into any Matter ecosystem — Apple Home, Google Home, SmartThings, Alexa, Home Assistant. Do not share once the device is paired — anyone with the code can commission it into a fresh fabric.

    Matter QR payload (Connectivity Standards Alliance spec). Format is MT: + base38-encoded CBOR. Manual pairing code (11 digits) is the fallback for devices without a QR. Every Matter-certified product is shipped with one from the manufacturer.

    WalletConnect v2 (now called Reown) URI. Generated by the dApp when a user clicks "Connect Wallet". Scanning with MetaMask, Trust, Coinbase Wallet, Phantom, Rainbow, Zerion, and 300+ other wallets completes the pairing. Session-specific — URIs are single-use.

    NFT claim / mint URLs from thirdweb, Reown, Zora, Manifold, or any chain-aware frontend. Scanning opens the claim page in the user's browser; WalletConnect or injected provider handles the on-chain mint. Works across Ethereum, Base, Polygon, Optimism, Arbitrum, Zora, Solana (scheme-dependent).

    Tailscale auth-key URL (ephemeral or reusable) from the admin console. Scanning on a new device triggers the auth flow. Works for Tailscale, Headscale (self-hosted), and compatible forks. Don't publish reusable keys in public QRs — anyone can join your tailnet.

    Works for any ActivityPub-compatible server (Mastodon, Pleroma, GoToSocial, Akkoma). Profile URL for sharing; OAuth authorize link for signing into a third-party app.

    Use this if you're printing a pet tag, key-chain sticker, laptop label, water-bottle decal, or anything else you want returned if lost. Scanner sees an "if found" contact prompt; owner is never exposed until they choose to respond.

    No account, no tracking, no service that can paywall your tag. The QR goes straight to your chosen contact method with a pre-filled "I found this" subject line. Works for pet tags, luggage, bike locks, cameras, anything with a visible printable surface.

    PayID er Australiens øjeblikkelige betalingsadresseringstjeneste. Virker med alle NPP-aktiverede australske bankapper.

    Why Abundera QR

    What is a SMART Health Card?

    A SMART Health Card (SHC) is a W3C-style verifiable credential for health information — a signed FHIR bundle, compressed, encoded as a numeric shc:/ URI, and rendered as a QR code. It was developed by the Vaccine Credential Initiative (VCI), a coalition of Microsoft, Salesforce, Oracle, the Mayo Clinic, the Commons Project, MITRE, and Epic, and adopted by the CDC, California, New York, Quebec, the EU (as part of the Digital COVID Certificate interoperability), and 30+ other health authorities.

    The QR is tamper-evident: the JWS signature binds the health data to the issuer's public key, which a verifier retrieves from the issuer's /.well-known/jwks.json. Scan with the SMART Health Card Verifier app (Apple / Android) or any compatible health wallet and you see a green check, the issuer name, and the decoded credential.

    Why the numeric encoding?

    Each character of the JWS is encoded as two base-10 digits — the character's Unicode ordinal minus 45. This lets the QR use the efficient Numeric encoding mode, which packs about 20% more data than Binary mode. A typical vaccination record fits in a V22 QR (~1,191 digits). Longer bundles get chunked: shc:/1/3/..., shc:/2/3/..., shc:/3/3/.... In practice, production SHCs rarely need chunking — issuers trim bundles to single-chunk size.

    What's encoded inside?

    The JWS (after chunk-reassembly and base-10 decoding) is a compact-serialised JSON Web Signature. The payload is a DEFLATE-compressed JSON FHIR bundle with one or more Immunization, Observation, or Patient resources. The JWS header carries a key ID (kid) that the verifier uses to fetch the issuer's ES256 public key.

    What this generator is not

    We do not issue SMART Health Cards. An SHC's value is its cryptographic signature from a trusted health authority (CDC, state health department, hospital, pharmacy). A self-signed card verifies as untrusted by every SHC verifier app. To get a signed shc:/ URI, log in to your provider's patient portal (Epic MyChart, Cerner HealtheLife, CVS, Walgreens, state immunisation registry) and export it from the Health Card download UI. Paste the URI here; we wrap it as a QR for printing, sharing, or saving.

    Frequently Asked Questions

    Where do I get a SMART Health Card to encode?

    From your healthcare provider's patient portal. Epic-based MyChart (most US health systems), Cerner HealtheLife, CVS, Walgreens, Walmart Health, and state / provincial immunisation registries (California Digital Vaccine Record, New York Excelsior Pass, Quebec VaxiCode) all offer SHC download. Look for a 'Share COVID-19 Vaccination Record', 'SMART Health Card', or 'Immunisation Record QR' option.

    Can I create my own SMART Health Card?

    Technically yes — anyone can generate a self-signed shc:/ URI — but no verifier app will trust it. SHC value comes entirely from the issuer's signature being in the VCI Directory or the CommonTrust Network. Self-signed cards show as untrusted red warnings.

    What's the difference between a SMART Health Card and the EU Digital COVID Certificate?

    Different payload and signing standards. SHC uses W3C Verifiable Credentials on FHIR with ES256-signed JWS. The EU DCC uses CBOR Web Tokens with COSE signatures. Interoperability bridges exist (the CommonTrust Network accepts both) but the QR payloads are not interchangeable.

    Why is the QR so dense?

    SHC packs a compressed FHIR bundle plus a cryptographic signature into a single QR. Even with Numeric-mode encoding and deflate compression, a full vaccination history can approach the V22 QR limit (~1,191 digits = ~550 FHIR bytes). Use a high-quality print with ECC level L or M and at least a 2-module quiet zone.

    What about the multi-chunk shc:/1/2/... format?

    Production SHCs rarely use chunking — the VCI recommends trimming bundles to fit a single QR. If you do need to chunk, paste each chunk in order and generate one QR per chunk. Verifier apps scan them sequentially and reassemble before JWS verification. Chunk one: shc:/1/2/[digits], Chunk two: shc:/2/2/[digits].

    Does the QR contain my medical record?

    It contains whatever FHIR resources the issuer included — typically the minimum for the credential's purpose: name, date of birth, vaccine manufacturer / lot / date for immunisation records; test type / result / specimen date for lab results. A full EHR is not encoded. Treat the QR as sensitive: name + DOB + provider-visible health fact is PHI under HIPAA.

    Can I revoke or update a SMART Health Card?

    Not directly — the QR is a signed snapshot. If the underlying record changes (correction, new dose, revocation), your provider issues a new shc:/ URI. Verifier apps check the issuer's revocation list (if published) via the key ID. Old QRs keep decoding but may show as revoked.

    Is this format used outside vaccination records?

    Yes. SHC is a general-purpose W3C Verifiable Credential on FHIR — valid for any FHIR resource. Active deployments include lab results (PCR / antigen), immunisation histories (childhood + travel), prescriptions (pilot programs), discharge summaries (some Epic deployments), and insurance membership cards (early trials).

    Which apps verify SMART Health Card QRs?

    SMART Health Card Verifier (Apple App Store / Google Play), CommonPass, VeriFLY, CLEAR Health Pass, Apple Health (built-in since iOS 15.1), Google Wallet (since 2022), and Epic MyChart. Built-in iPhone camera recognises shc:/ URIs and hands off to Apple Health automatically.
