UPC-A
:
Numeric, 11 Digits
Standard in the USA. for items sold to the public. UPC-A contains numeric data only and
encodes a 12 digits number. The first one is the number system character, the next 5 digits
are the supplier ID, the next 5 digits are the product number and the last one the required
checksum character. You don’t need to specify the checksum digit as the Barcode module
recalculates it.
A digit is described by 2 bars and 2 spaces and its width is calculated as 7 thin bars.
The number character is printed as text on the left side or the bar code and the checksum
on the right side.
The system number can have the following values:
0 or 7: Regular UPC codes
2:
Random weight items
3:
National Drug Code and National Health Related Items Code
4:
For use w/o code format restriction and with checksum for nonfood items
5:
For use on coupons
1,6,8,9: Reserved
UPC-E:
Numeric, 6 digits
Ideal for small packages because of its data compression. It contains the same
information as the UPC-A except that there are minimum 4 zeros, which are suppressed. It
reduces the number of digits from 12 to 6. The Barcode module accept the Zero
Suppressed version of UPC-E in both version of the data, compressed and
uncompressed. If data comes uncompressed, the Barcode module will perform
automatically the compression.
A digit is described by 2 bars and 2 spaces and its width is calculated as 7 thin bars.
Note that caption text below the barcode can be activated to verify checksum
calculation.
