I am working on a project where i want to emulate Credit/Debit card using pn532 NFC module. I tried to find out the protocol to in which i can send the credit/debit information to the Credit/debit card reader. I tried to search about this but didn't get proper document. I need help on this.
- What all information should i send to reader?
- Exchange protocol in Credit card emulation mode.
You can find an explanation of how to put a PN532 into card emulation mode in this answer.
The protocols for (contactless) credit cards are specified by EMVCo. You can find their specifications on their website.
