BC412 with a verifiable check character

Wafer-tracking systems that verify a check character at the reader (rather than trusting an unchecked value) use this generator with a computed Modulo-35 check character added.

Same generator, one preset applied

This experience uses the same BC412 capability as the primary generator, with a computed check character added ("includecheck": true) instead of the primary's unchecked default.

Example data

The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.

Workflow

Enter your wafer/reticle identifier, confirm the preview, then export SVG for the direct-marking artwork.

Job-specific settings

No job-specific options beyond the added check character are applied here.

Scanning notes

BC412 requires a reader configured for BC412's own 35-character alphabet, the same reader class used for the primary's unchecked value.

Common mistakes

A character outside BC412's own 35-character alphabet is the most common rejection.

Standard

BC412 is standardized by SEMI as SEMI T1-95.

No other capability in this catalog uses BC412's own alphabet or checksum.
