Method and apparatus for credit card verification.

摘要

The validation system includes a credit card having digital data recorded thereon representing the image of at least one authorised user and authorising data. A reader reads the digital data recorded on the credit card. An algorithm unit provides an encryption algorithm for encoding portions of the digital data. A processor encodes the digital data read from the credit card with the provided encryption algorithm. A unit displays the digital image representing the authorised user. A second processor receives portions of the encoded digital data from the first processor. A storage unit has stored digital data corresp. to the authorising data recorded on the credit card and encrypted with the provided encryption algorithm. The second processor compares the received portions of the encoded digital data from the first processor with the digital data from the storage unit to provide a validation signal when a correspondence is detected.
