* \brief Demo application
*
* This demo shows how to poll for several types of NFC cards/devices and how
* to exchange data with these devices, using the RFAL library.
*
* This demo does not fully implement the activities according to the standards,
* it performs the required to communicate with a card/device and retrieve
* its UID. Also blocking methods are used for data exchange which may lead to
* long periods of blocking CPU/MCU.
* For standard compliant example please refer to the Examples provided
* with the RFAL library.
