摘要

Purchase of an item bearing a unique identification code is verified by (a) ascertaining the identification code of an item to be purchased (60); (b) acquiring data representative of color features of the item to be purchased (64); and (c) comparing the data representative of color features of the item to be purchased to data representative of expected color features for items having the same identification code (74). Other physical characteristics of an item, such as height, may also be employed.
