NFC/Bluetooth sticker goes into production

Power needed anyway

The device can actually work as a passive tag or as a reader, so a power supply is needed regardless of Bluetooth. Makes sense, because as a passive tag it would have nothing to send to the phone via Bluetooth.

The only way that comes to (my) mind for the thing to use Bluetooth with a passive tag is to dynamically change the content of the tag while the instructions for the change would be passed from the phone to the tag by Bluetooth.
