Description
This versatile RFID reader/writer module is a compact, dual-interface solution for enabling contactless card interactions in modern devices. It combines a small-form-factor main board with a detachable external antenna, making it ideal for integration into slim-profile equipment like digital signage players, access control panels, and self-service kiosks. Operating at the standard 13.56MHz frequency, it facilitates both reading and writing operations on popular IC cards and NFC tags, including MIFARE and NTAG. Its standout feature is the dual USB and UART interface, offering plug-and-play connectivity for end-user applications and a programmable serial interface for embedded development.
特征
-
Space-Saving Dual-Interface Design: An ultra-compact main unit paired with a separate antenna allows for flexible installation in devices with limited internal space. It provides both USB and UART connectivity in one module.
-
Plug-and-Play & Developer-Friendly: The USB interface emulates a keyboard (HID), allowing for instant use with any system accepting keyboard input. The UART interface offers full control for custom embedded applications and firmware updates.
-
Broad Compatibility: Supports reading and writing of common 13.56MHz RFID/NFC cards and tags (MIFARE, NTAG, ISO14443A). Compatible with Windows, Linux, Android, and various microcontrollers.
-
Robust Construction: Designed with a sturdy plastic casing and a high-frequency inductance antenna for stable performance and consistent read/write range in various environments.
