Code128
Timeline (last 90 days)
The Code128 specification defines a mandatory check character (checksum), located after the start character and before the data characters, calculated by a weighted mod-103 algorithm, used to verify data integrity during decoding.
Whether the Code128 check character must be encoded depends on the specific implementation and reader behavior; many lightweight generators omit it, and some decoders can still output data when the check character is missing but do not perform verification.
