I was thinking..

When Flipper can write saved NFC scans is there anything like a simple ring with writable nfc chip inside?

Cause there wouldn't be need for apple/android pay when I can simple copy my debit card nfc chip, write it on another chip (in this case in a ring) and pay by waving my hand and occasionally using pin like normally with debit card.

No need for apple or google to know all about my purchases..

Won't work for credit/debit cards, can't extract the encryption keys needed to confirm transactions from the original card. You can try it without the ring, just use the flipper to try and emulate the bank card and use the flipper as if it was your card. Won't work.

To get a bank card ring you could open up the card, take the electronics inside, and diy a ring with it inside. I'm sure someone out there has done it
