The iDTronic R835 embedded RFID reader module reads and writes to almost any 13.56 MHz transponder, including NXP’s Mifare and DESFire. The module, which is just 3.45×0.58×0.3 cm, integrates an antenna to enable reading ranges of up to 8 cm, depending on the tag, antenna, and environmental conditions. Further, the antenna transmits data at speeds of up to 115,200 bps.

The R835 module is equipped with a 3.3 VDC to 5 VDC power supply and requires less than 100 mA for operation with a DESFire transponder. A TTL-based interface and Molex connector allow easy integration with Windows, Linux, and Android systems. The module reads and writes to Mifare Classic, Ultralight, DESFire, Smart MX, Plus S, and Pro X transponders.

Developers can use the R835 embedded RFID reader module in medical devices, vending machines, and identification products. It withstands temperatures and liquids at up to +80°C. The R835 comes with a software development kit for Windows or Linux applications and includes command protocols, source codes, and a Windows-based demo application.
