Generate PosiCode A codes that scan.
PosiCode version A. Type the payload for PosiCode A below — validation, check digits and a local scan-test run in your browser before anything exports.

Advanced (GS1, checks, profiles, retail add-ons, supply-chain carrier)
Style (readable text, bar height, export size)
Bar height stretches bars vertically, which scanners ignore (only horizontal timing matters). The SVG download keeps the engine's exact geometry.

Usage
PosiCode A labels industrial parts, documents and work orders: print it on badges, boards and bins where rugged 1D scanners operate.
- PosiCode A on asset tags for workshop tracking
- PosiCode A on work-order paperwork for line-side scanning
- PosiCode A proofs exported as PNG for quick sharing
Shape
Pros
- PosiCode A tolerates industrial printers, labels and badge stock.
- Case folding, padding and check rules are explained before encoding.
- PNG and SVG exports cover both quick sharing and print.
- The self-verify readout shows exactly what a scanner will observe.
Cons
- PosiCode A is wider per character than 2D codes for long payloads.
- Dense narrow bars demand close, steady photography when verifying.
- Damaged or smudged labels lose characters with no error correction.
- Colored or low-contrast prints scan poorly.
Form requirements
- Enter ABC123.
- Printable ASCII; generate-only because no qualified local reader is available.
- The symbol is decoded again locally before preview and downloads unlock.

How it works
Three steps, all on your device.
The same engine that reads barcodes writes them — every symbol is decoded again before you see it.
Type the payload
Every symbol is validated and decoded again on your device before it is shown.
Download and print
Take a resolution-independent SVG for print or a PNG for sharing. Nothing is uploaded.

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.
