In Line Group

The In Line Group defines a one time instance of a group that occupies

one character position in the template. Use this for unique groups of char-

acters that occur only once.

Checksums and Weighting

A checksum reduces the probability of misreads. There are two types of check-

sums: row and block. For additional checksum protection, there are four differ-

ent weighting schemes: 1, 12, 13, and 137. The checksum calculation is based

on modulo arithmetic. The modulo factor may vary from 6 to 36.
