Bar Code Specifications
*1 The check digit is automatically calculated in accordance with input data.
For EAN-13, EAN-8, UPC-A, and ITF, the check digit is appended at the end
of the printed digits. For CODE39 and CODABAR, the check digit is ap-
pended one digit before the final digit (when a check digit is used).
*2 UPC-E includes a check digit, but it is not printed as a numeral below the
bar code.
*3 The number of digits printed below a bar code equals the input characters
plus automatically appended characters.
