Mifare IC Card Block Encrypt Read/Write Module series encapsulates the complex ISO14443 protocol and read / write card-related operations. All read and write operations on the MF1 card become a few simple instructions. Users do not need to understand the complex ISO14443A protocol, only need to understand the structure of the card used by a simple instruction to operate the card reader module, which consists of all the complex operation of the MCU card reader module to complete.
The Block Encrypt R/W Module is widely used in non-contact smart water meters, power meters, gas meters, electronic door locks, traffic One Card Solutions reader, desktop card reader, access attendance card reader, car electronic induction lock supporting, office / shopping malls / Safety control box, a variety of security systems and production process control.
