Some RFID applications place higher demands on data security, e.g. applications in the field of e-payment or ticketing. Here, transponders according to ISO14443A or MIFARE® technology are often used. The QR14 plug-in module is suitable for all these applications where transponders need to be read or written in a space-saving and cost-effective manner. The module supports the protocols MIFARE Classic and MIFARE Ultralight®. Furthermore, the QR14 plug-in module can also be used to read and write NFC chips of NFC type 2.

As a plug-in module, it can be easily integrated into your own electronic assemblies and delivers good RFID performance. With the integrated antenna, a reading range of up to 50 mm is possible. The communication to the microcontroller is done via UART so that an integration can be easily implemented.
