Chapter 3 Bar Codes
Readable Data
The optional readable data field provides a readable interpretation of the bar
code data. Readable data is printed below the horizontal bar code symbol,
and to the left of a vertical bar code symbol. The lower guard band is provided
when the readable data field is selected.
Check Digit
The check digit provides the means of verifying accurate scanning. For MSI
Types G, H, I, and X, a specific check digit, Modulo-10 or Modulo-11 (or both),
is automatically calculated and appended in the bar code symbol. MSI Type F
does not use a check digit.
