of wide bars in the group determines which character is
encoded; spaces are insignificant. Only numeric characters
(0 to 9) and START/STOP characters may be encoded.

Encryption Encryption is the scrambling and coding of data, typically
using mathematical formulas called algorithms, before
information is transmitted over any communications link or
network. A key is the specific code used by the algorithm to
encrypt or decrypt the data. Also see, Decryption and Key.
EPC Electronic Product Code,
The Electronic Product Code is an electronically coded 64-
