USB NFC dongles are used in home banking to authenticate a user or a transaction. They have a simple user interface and typically connect to a PC though a USB connector, which is also used to power the device, and a HF NFC reader typically with a very small form factor antenna.

The main difference with a typical NFC/HF reader is their very small form factor antenna, but thanks to the excellent characteristics of our ST25R NFC/HF readers, a good read performance is achieved.

The great reading ranges of our ST25R NFC readers and our ultra-low-power STM32L4 microcontrollers can help in the design of highly effective NFC dongles.
