摘要

A credit-card reader having a built-in digital camera for capturing a template signature and an email address on a credit card. The email address is identified by an optical character recognition program and input to an email system. A test signature is entered on a touch-pad input device and both the test and the template signatures are normalized and displayed for verification. Action buttons are provided on the display screen for enforcing the signature verification actions. The system enables the transmission of an electronic receipt selectively controlled by the customer and eliminates the needs of physically handling a credit card for signature verification and manual input or pre-registration of an email address for an electronic receipt. The computer-assisted features enables a central system of signature verification for purchase transactions at self-service check-out counters.
