3.3V 5.0V 13.56MHz Serial NFC Reader Module High Frequency Read Write Card

13.56MHz High-Frequency Serial NFC Read/Write Card Reader Module

DK25-ST series contactless IC card reading and writing module adopts 13.56MHz radio frequency signal and supports reading and writing operations on IC card (label); the communication interface of the module is UART port, and the user only needs to send serial commands to achieve communication with the card. Data interaction; in terms of card recognition, the read-write module has excellent compatibility and supports most of the

ISO14443A&ISO14443B/15693/18092 and other protocol card types, support APDU command; suitable for all kinds of NFC recognition embedded device applications.

Product Features:

➢ Small size and high cost performance;

➢ UART serial command read and write operations, no need to develop the bottom layer, simple and easy to use;

➢ 13.56MHz, good compatibility, support most card types on the market;

➢ Long distance to read and write cards (a reasonable read and write distance of 10~80mm with antenna tag);

➢ The module has a watchdog and never crashes;

➢ Support customized design;
