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.pastedImage_2.png
