A Fingerprint Payment System Based on FPGA
2016
Fingerprint authentication is one of the most reliable and most widely used authentication methods. With the maturation of fingerprint recognition technology and the reducing cost of fingerprint reader, fingerprint authentication is more and more widely used in daily payment situation. This paper presents a new offline fingerprint payment system based on Artix-7 FPGA (XC7A35T-ICPG236C). This system provides a more secure and convenient payment solution by fingerprint payment instead of cash or IC card payment. This paper describes the integration of each modules of the system including fingerprint identification module, display module, and keyboard input module. The system provides a friendly user interface through a monitor showing the consume information. The keyboard operates the functions such as account management, recharge and consumption. Fingerprint module authenticates customer ID and thus completes the payment. The system is implemented purely on FPGA, which is more secure and efficient compared to traditional payment system.
