NFC Tandem concept: combine NFC reader and connected tag solution

[#1]

NFC Tandem offers best of both worlds:

An NFC reader and a passive connected tag sharing one antenna. A user can interact with the device when it is powered off (through the NTAG I²C plus); when the device is powered, it can interact with cards, P2P devices or other connected tags.

NFC Tandem Uses Cases and Applications:

One-touch pairing WiFi with phone, or card Bluetooth with phone, headset, speaker
IoT network node commissioning
User identification with badge or phone
Authentication and configuration of consumable and accessory
Zero-power parametrization
Zero-power firmware update
Zero-power diagnosis and maintenance
