Dear NFCRing teamyour work are very interesting, thank you for bring it to real world
I had questions about NFC Ring with Payment technology,

Q1. is it work with 'Mastercard paypass' and 'Visa paywave'?
Q2. do I need to create initial setup from Ring?
Q3. if some bank had NFC payment feature, can you ring clone that ID? (Please have a look Emirates NBD Pay)
