This allows reading either TD1, TD2, Passport, Visa Type A, or Visa Type B without switching between
these options. It automatically recognizes the travel document read.
To choose a variant, scan one of the following bar codes. Selecting the following OCR-B variants automatically
sets the appropriate OCR Lines on page 256. These five variants invoke extensive special algorithms and
checking for that particular document type:
Variant OCR Lines Setting

TD1 ID Cards 3
TD2 ID Cards 2
Visa Type A 2
Visa Type B 2
Selecting one of the ISBN Book Numbers automatically applies the appropriate ISBN checksum, so you do not
need to set this.
