[Feature Request] NFC reader for seed input #492

Seedsigner is a great device, but having QR codes around with the seed is a bit dangerous IMO. I believe it would be much more secure to have the seed stored in a blank NFC card (like the tapsigner: https://tapsigner.com) or object (an NFC chip can be concealed anywhere, for instance: https://satschip.com).

A small NFC reader hat should be added to the seedsigner, along with the software option to read the seed via NFC.
