 * @brief NFC 7 SPI Click example
 *
 * # Description
 * This example demonstrates the use of NFC 7 SPI Click board by handling the detection
 * and processing of various NFC technologies and protocols, and ensuring the application
 * can respond to different NFC card types (A,B,F,V).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger, performs the Click default configuration and
 * reads the device firmware version.
 *
 * ## Application Task
 * Waits for an NFC device to be discovered, checks if it supports a known NFC technology, 
 * and then handles the device based on its protocol. The application continues processing
 * the device (reading and writing information) and waits until the card is removed.
 * Once the card is removed, the discovery process is restarted to detect a new NFC device.
