As part of our mobile app for Electrical Vehicle (EV) charging, we are creating a NFC enabled prepaid reward card. Can you help us in understanding following data flow so that we can use this pass in our application in conjunction with charge station NFC reader and our backend server
1. We are able to create the Pass and add it in Apple Wallet. However the NFC reader is not able to read this pass. Is there anything else required to be done in order to enable this card for NFC data exchange?
2. Once exchanged via NFC, the reader is expected to send this data to our server for validation. We are unable to find any documentation on apple developer site on this data exchange front. Can you help us in understanding following
2.1 What data is exchanged over NFC for our pass? We are hoping data from pass.json is passed over NFC to the reader. Can we get a reference of which all data is exchanged over NFC? Is the exchange data encrypted?
2.2 As part of our use case, NFC reader is expected to pass this data to our backend server for validation. We are hoping that if any of the data from pass.json is exchanged over NFC than that data we shall be able to use to validate it on our backend. Can you please provide any documentation pointers for us to get this done.
2.3 After reading the pass data over NFC, is NFC reader required to talk to apple server for further decryption of data received via NFC?
