HX881-T-N Embedded RFID & NFC Read/Write Module is a contactless smart card read/write module operating at a high frequency of 13.56MHz, developed based on the international standard protocols ISO/IEC 14443–1, -2, -3, -4, and ISO18092. It supports TYPE A and TYPE B chip cards, CPU card reading and writing, and NFC cards with a board-wire separation design. It can be customized in bulk with SPI interface, UART interface, and USART interface, making it easy to embed into terminal devices such as charging piles, smart wine cabinets, attendance and consumption machines, advertising tablets, medical electronic equipment, and more.

HX881-T-N Embedded RFID & NFC Read/Write Module is designed using a highly integrated dedicated card reading chip, advanced watchdog, and voltage monitoring circuit solutions. It features high integration, strong anti-interference capability, compact size, and more stable performance. The product provides underlying communication protocols to facilitate secondary development and application by customers.
