RC522 RFID Reader/Writer Module Kit with Tags, 13.56MHz, SPI, for Arduino

product description Near Field Communication (NFC), also known as Near Field Communication Distance wireless communication is a high-frequency wireless communication technology that allows electronic devices to communicate over short distances Non contact point-to-point data transmission (within ten centimeters) is used to exchange data between them. This technology evolved from contactless radio frequency identification (RFID) and is backward compatible RFID, Originally developed by SONY and PHILIPS respectively, it is mainly used for mobile phones and other applications Provide M2M (Machine to Machine) communication in handheld devices. Due to the natural security of near-field communication, NFC technology is considered to be useful in mobile phones The payment and other fields have great application prospects. Meanwhile, NFC has also been recognized for its superior security compared to other wireless communication technologies The National Internet of Things School Enterprise Alliance is compared to a "secure dialogue" between machines.
