Design of Payment System Based on FPGA and Fingerprintidentification
With the rapid development of science and technology,large payment systems such as Alipay and WeChat have been widely integrated into people's lives,but they are not suitable for application scenarios such as consumption and recharge in small stores.In order to realize a small payment system with independent records,this paper proposes a fingerprint payment system based on FPGA.The system uses keyboard,display,sensor and other peripherals.When the key-board gets the input information,it sends the signal to FPGA and displays it to the display through VGA protocol.The fingerprint module completes data transmission and control through UART communication protocol,obtains the control information sent by FPGA,and then enters the entry,verification and other states.The system joint debugging shows that it has the func-tions of account opening,inquiry,recharge and consumption,does not rely on the identification mode of the account,and relies on the fingerprint search results,which is suitable for small-scale application scenarios.
