ACCOUNT IDENTIFICATION

摘要

A method of account identification is performed on suitably programmed computing apparatus. An account number comprising a plurality of numeric characters is assigned to an account. The characters of the account number are divided into a numeric identifier and a convertible string. The convertible string is compressed into a compressed convertible string using an expanded character set. There are fewer characters in the compressed convertible string than in the uncompressed convertible string. A compressed account number is provided comprising the numeric identifier and the compressed convertible string. This may then be used in transactions without compromising the original account number while retaining the identifier for use in identifying transactions. A method of performing a transaction is also described, as is suitable apparatus for carrying out the methods described.
