Abstract: Due to the different manufacturers and different production conditions,the performance of NFC purchase card differences,To improve conformance,this paper designed an NFC purchase card communication tester based on an embedded platform.Based on the embedded platform including FPGA and ARM.The paper realizes the modulation,demodulation,encoding and decoding of NFC communication through FPGA technology,and realizes the information exchange between PC and FPGA through ARM.In addition,by developing user interaction software used on PC,testing personnel can control instrument output parameters in real time to increase testers flexibility and applicability.
