以降低的不透明度渲染在 QR 背后。自动强制 EC=H,使 QR 仍可通过照片扫描。
批量生成
上传 CSV 文件,一次最多可生成 500 个二维码。每一行都会生成独立的二维码——您可以选择模板,也可以逐行自定义 21 项属性:颜色、边框、点/眼/眼球样式、渐变、透明度、尺寸、纠错等级、格式、内置 logo 等。
21 列:type, data, filename, frametext, frame, template, fgcolor, bgcolor, size, ec, dotstyle, eyestyle, format, logo, gradient, g2, gtype, gangle, transparent, eyeball, eyecolor。仅 type 和 data 为必填项。使用 | 分隔 data 内的字段(例如 ssid|password|WPA)。
支持全部 20 种二维码类型,包括 URL、WiFi、vCard、MeCard、Email、SMS、Event、Location、UPI、SEPA、PayPal、Crypto、Micro QR 和 rMQR。下载示例 CSV,查看所有列、40 个模板、11 种边框样式以及 12 个内置 logo 的实际效果。

What is Data Matrix?
Data Matrix is a square (or rectangular) 2D matrix barcode standardised as ISO/IEC 16022. It packs significantly more data per unit area than a 1D barcode, scans reliably down to ~3 mm sides, and tolerates damage thanks to Reed-Solomon error correction. It's the dominant 2D format outside of QR for industrial use.
Where Data Matrix is mandatory or dominant
- Healthcare UDI — FDA UDI and EU MDR require Data Matrix on most medical devices and packaging.
- Pharmaceutical packaging — FMD (EU Falsified Medicines Directive) mandates Data Matrix with GTIN, batch, expiry, serial.
- Electronics direct-part marking — laser-etched onto PCBs, semiconductor wafers, and connectors.
- Aerospace / automotive parts — mil-std 130, ISO 22742 supply-chain marking.
- Tobacco track-and-trace — EU TPD requires Data Matrix on every cigarette pack.
Limits
- Up to 2,335 alphanumeric or 3,116 numeric characters in the largest size.
- Smallest practical print size: ~3 mm side at 600 DPI.
- Error correction is fixed (Reed-Solomon ECC 200) — no user choice of EC level.
Note on styling
Data Matrix is not a QR code. The QR-style controls in our generator (eye styles, dot shapes, gradients, frames, centre logos) don't apply — they assume the QR finder/timing pattern. Foreground and background colours are still configurable.
支持 26 种语言
完全翻译的界面、原生字符渲染,以及对阿拉伯语和乌尔都语的从右到左支持。
Frequently Asked Questions
Can I add a logo in the centre?
No — Data Matrix has no built-in error-correction headroom for logos. The whole symbol is data + ECC; covering any region risks an unscannable code.
What about GS1 Data Matrix?
GS1-formatted Data Matrix uses Application Identifiers ((01) for GTIN, (10) for lot, etc.) embedded in the data string. Paste your full GS1 element string (e.g. (01)09506000134352(10)ABC123(17)260101) into the Content field; the encoder is the same.
Why is my Data Matrix rectangular instead of square?
bwip-js auto-picks the optimal symbol shape from the ISO 16022 size matrix. Short payloads tend to be square; long payloads can fit better in rectangular variants. The scanner doesn't care.
Does this work for direct-part marking (DPM) inspection?
The generator outputs the symbol image. Whether your laser, dot-peen, or ink-jet equipment can mark it depends on your process. The data structure is correct.
Can I generate Data Matrix in batch?
Yes — use the batch CSV with type=datamatrix. The data column accepts any text. Output is monochrome; FG/BG colours apply to the live UI.
Why did you pick bwip-js instead of writing your own encoder?
Reed-Solomon ECC 200 + ISO 16022 symbol layout is a non-trivial 1500+ line implementation that's been independently verified across thousands of production deployments via bwip-js. Reinventing it would invite scanning bugs.
Will scanners that say 'QR code reader' read Data Matrix?
Most modern scanner apps (built-in iPhone Camera, Google Lens, ZXing-based apps, all enterprise scanners) read both. Strict 'QR-only' apps won't — check the app's spec.
