1、Overview

ER302 USB NFC RFID module is a PC-linked contactless smart card reader/writer module developed based on the 13.56 MHz Contactless (RFID) Technology. It supports ISO14443A, MIFARE®1k, MIFARE®4k, MIFARE Ultralight®, NTAG216/215/213/203.

ER302 USB NFC RFID module use USB port to act as a virtual COM port. The proximity operating distance of YHY523U is up to 10 cm, depending on the type of contactless tag in use.

ER302 USB NFC RFID module is ideal for secure personal identity verification、access control、e-payment、e-ticketing for events and mass transit、toll road fare collection and network authentication.

We embeded an MCU on this module. By sending command via USB interface, you can make it work. Operation is very easy. Most work is done by the embeded MCU.
