Generate Han Xin Code symbols that scan.
Chinese Sensible Code generated by BWIP and verified locally by the pinned extended ZXing-C++ reader. Configure Han Xin Code below — Versions 1–84, EC Levels 1–4 and masks 1–4 can be pinned or left automatic. Output is reader-verified locally before display; GS1 mode stays disabled until the reader path is qualified. Every symbol is decoded again on your device before export.

Advanced (error correction, shape, GS1)
Style (colors, frame, caption, export size)
Symbol contrast 100.0% (minimum 40%). The companion color adjusts automatically to hold the minimum; downloads additionally require the colored symbol to re-decode.
Outer frame
Frame and caption ship in the SVG download; PNG exports the bare symbol.

Usage
Han Xin Code serves specialty parcel, healthcare and industrial marking: use it where its fixed geometry and carrier rules already govern the workflow.
- Han Xin Code on parcels and healthcare packaging per carrier rules
- Han Xin Code on industrial carriers with pinned versions and masks
- Han Xin Code proofs verified locally before any export unlocks
Shape
Pros
- Han Xin Code scans on modern phone and industrial imagers.
- Every symbol is read back locally before preview or download.
- SVG export stays sharp for print; PNG covers quick sharing.
- Only the controls this symbology accepts are shown.
Cons
- Han Xin Code needs calm quiet zones — nearby text breaks detection.
- Glare, blur and low contrast are the usual reasons a symbol will not read.
- Screenshots prove scannability, not print quality grading.
- Custom colors stay locked until contrast and tinted re-decode pass.
Form requirements
- Enter Numeric, ASCII, Chinese or binary text.
- Versions 1–84, EC Levels 1–4 and masks 1–4 can be pinned or left automatic. Output is reader-verified locally before display; GS1 mode stays disabled until the reader path is qualified.
- Downloads stay locked until the local read-back reproduces the payload.

How it works
Three steps, all on your device.
The same engine that reads 2D codes writes them — every symbol is decoded again before you see it.
Tune and style
Only the controls this symbology accepts are shown; every symbol is read back to prove it scans.
Download and print
Take a resolution-independent SVG or a PNG at your chosen module size. Nothing is uploaded.
Questions

If you manage servers by hand, see the engineering services behind this tools series.
What can I encode in Han Xin Code?
Versions 1–84, EC Levels 1–4 and masks 1–4 can be pinned or left automatic. Output is reader-verified locally before display; GS1 mode stays disabled until the reader path is qualified. Example input is prefilled when the page loads.
How does Han Xin Code stay scannable?
Han Xin levels 1-4 (L1-L4). Keep the quiet zone calm, use black-on-white for print, and export SVG for anything that gets resized.
Is my data uploaded anywhere?
No. Encoding and verification run entirely in your browser — the page makes no network requests with your data, stores nothing, and wipes the field after ten idle minutes.
