RAdio Frequency IdentificatioN (RAIN) is an Ultra-High-Frequency (UHF) RFID technology ensuring reading ranges up to 10 m. Widely used in logistics to track and inventory goods in a warehouse, the reader can be embedded into handheld devices, tablets, POS solutions, smart kiosks, smart mirrors, and shelf readers as well as gateways or fixed readers.

We offer high-performance, low-power ST25RU3993 RAIN RFID UHF reader ICs that that together with our 32-bit STM32 microcontrollers can help develop small form-factor, low-power RAIN UHF readers.
