Data Formats of Barcode Types
UPCA
11 numbers are transferred for the UPCA code. The 12. digit represents the
check number. The even figures of the information have a factor of "3", the
uneven figures a factor of "1". Counting begins from the left. The resulting
cross sum is divided by 10. The remaining figure is subtracted from the modul
(10). If the remainder is "0", the check number is also "0".
Example
For remainder “0” the check number is also “0”.
UPCE
For the UPCE barcode type, seven numbers are transmitted. The 8. digit is
the check number. The uneven figures of the information have a factor of "3",
the even figures a factor of "1". Counting begins from the left and the resulting
cross sum is divided by 10. The remaining integer value is subtracted from the
modul (10). The result is transmitted as the check number (c).
Example
For remainder “0” the check number is also “0”.
Information 4 0 1 2 3 4 5 6 7 8 9 3
Factor
3 1 3 1 3 1 3 1 3 1 3
Product 12 + 0 + 3 + 2 + 9 + 4 + 15 + 6 + 21 + 8 + 27
Cross sum 107
10 (modul) - 7 (remainder) = 3 (check number)
