Abstract (en)

A signature verification method at a point of service (POS) work station requires only a single signature from a customer for purposes of verification and payment. Also, a signed receipt (22) is produced without requiring an additional signature. A first signature verification method begins by entering an account number by swiping a magnetic card containing the account number through a magnetic stripe reader (24). A POS terminal (14) sends the account number to a database (20). The database (20) sends a file signature associated with the account number from the database to the POS terminal (14). A customer enters a current signature by signing a representation of a receipt in a write input device (22) with a stylus (36). The current and file signatures are displayed one above the other on a monitor (16). Finally, an operator visually compares the current and file signatures. An alternative method visually compares a file signature with a signature on the back of the magnetic card (119), and then compares the card signature with a currently signed signature. <IMAGE>
