Abstract
A method of handling mail items includes, during a first sorting pass, taking a digital picture of each mail item, directing the mail item towards a sorting outlet bin, and deriving from the picture a digital fingerprint, and, during a second sorting pass, taking a digital picture of a current mail item to derive a fingerprint, performing automatic address recognition, and searching recorded address data for a match with the address data of the current mail item to identify a current bin to which the current mail item corresponds, so that, in order to search for a match between fingerprints, the search for matching fingerprints is conducted in an exploration space formed by the digital fingerprints that correspond to the current sorting outlet bin.
