A bar code (40) including a first linear bar code portion (12), and portions with two-dimensional bar codes (30A, 30B) at the ends of the first bar code portion (12). A separation (22) through the first portion (12). The two dimensional bar code at each end (30A, 30B) is inverted from the other end, and in an embodiment is also rotated 180 DEG , which enable the two-dimensional bar codes (30A, 30B) on separated parts of the single bar code (12) to be identical.
