Waveshare NFC Development Kit ST25R3911B Reader/Writer

This NFC development kit from Waveshare is based on the ST25R3911B NFC chip from STMicroelectronics and has an AT32F413 microcontroller, a 1.3 inch OLED display, four buttons, a microSD slot and an acrylic case. A program is flashed at the factory that reads NFC tags and writes images from the microSD card or via the serial interface to Waveshare's passive NFC e-paper displays. ISO14443A/B, ISO15693, FeliCa and ISO18092 are supported at up to 1.4 W output power.
