The RFID HF | NFC Embedded Reader – R831 is designed to support ISO 14443A/B + ISO 15693 as well as ICs of the NXP MIFARE family.
RFID HF | NFC Embedded Reader – R831 is equipped with an integrated antenna which enables reading ranges of up to 4 centimeters (depending on transponder type).

All variants are available as USB Virtual ComPort Read/Write as well as USB HID Keyboard Emulation (except DESFire version).
According to customer requirements, the HID output of the reader can be adapted in advance and adapted to the requirements of the application.

Due to its narrow design with dimensions of 71 × 17.2 × 9.4 mm, the RFID reader can also be integrated into applications with limited installation space. A integrated LED and the buzzer facilitate the status display during use. The RFID Stick Reader Module is a full RFID reader and writer with extremely compact dimensions. This allows RFID technology to be used in many different applications.

A complete software development kit and test software are included with the RFID HF | NFC Embedded Reader – R831.
