SM-HD6746 model high-frequency IC card reader module supports operations such as reading and writing IC cards such as Fudan and M1, deduction and recharge. Developed by NXP's highly integrated card reader chip MFRC522, it supports reading and writing operations on IC cards such as Fudan, Mifare1 S50, Mifare1 S70, Mifare UltraLight, etc. The module integrates the ISO14443 TypeA protocol. Developers only need to send simple commands through the communication interface to complete the reading and writing operations of the IC card without understanding the complex IC card communication protocol. Detailed development documents and complete development routines can reduce the difficulty of development, shorten the development cycle, and help you easily and quickly integrate today's most popular non-contact IC card technology into your system. It is widely used in charging pile management, book management, asset management, anti-theft and anti-counterfeiting, time attendance, access control, all-in-one cards, electronic tickets and other fields.
