Advanced (GS1, checks, profiles, retail add-ons, supply-chain carrier)
This symbology has no tunable options — the engine picks the densest valid symbol.
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
ITF (Interleaved 2 of 5) labels industrial parts, documents and work orders: print it on badges, boards and bins where rugged 1D scanners operate.
- ITF (Interleaved 2 of 5) on asset tags for workshop tracking
- ITF (Interleaved 2 of 5) on work-order paperwork for line-side scanning
- ITF (Interleaved 2 of 5) proofs exported as PNG for quick sharing
Shape
Pros
- ITF (Interleaved 2 of 5) 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
- ITF (Interleaved 2 of 5) 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 12345670.
- Digits only, even count (odd input gets a leading zero), 2–80 digits.
- The symbol is decoded again locally before preview and downloads unlock.
