发明名称 SMART CARD THAT STORES INVISIBLE SIGNATURES
摘要 A transaction card 10 for use in a transaction includes a memory 15 and pressure sensors 20 . The authorized user provides biometric data, such as a signature, by signing on the pressure sensors ( 20 ) using a pointer for storage in the memory ( 15 ) when the card is used for the first time. The signature is not visible on the card for added security. At the point of use of the transaction card ( 10 ), such as the point of sale, the user signs on an input device ( 50 ) such as a digital tablet, a tablet with pressure sensors or a slip of paper. This newly acquired signature ( 55 ) is compared with the signature stored on the transaction card ( 10 ), such as by displaying the stored signature out of the view of the user and comparing displayed signature with the acquired signature ( 55 ). The comparison may be performed by the service-providing associate or by a processor coupled to the input device ( 50 ).
