1. A method of confirming the identity of an item including an identifier, the method comprising: acquiring an image of the item including the identifier; extracting a first set of geometric point features from the image of the item; reading identification code data from the identifier included with the item; retrieving from a database a second set of geometric point features based on the identification code data, the database comprising sets of geometric point features associated with a plurality of known items; comparing via a processor the first set of geometric point features from the image with the second set of geometric point features retrieved based on the identification code data; and determining whether the item in the image corresponds to the identification code data read from the identifier included with the item based on the comparing of the first set of geometric point features with the second set of geometric point features.
