i recently started learning android programming at my university and as a final project i started developing nfc-hce payment app like Android Pay and/or Apple pay. I live in a small country where non of the nfc payment apps work so i cannot see in real life how it actually works">works. I was searching and i found about SwipeYours app and it's source code on GitHub and i am using it now to understand the basics of EMV application in mobile payment app. What i have now is commands for APDU select, from known AID card select, GPO command and READ_REC command.
Using my MasterCard PayPass card everyday i found out that the chip is holding my 10 last transactions and my question is now, how does the card gets all the information about transaction. I would like to implement that in my code.
And i know that only banks and card issuers can make such an applications fully functional because of the key for generating a cryptogram but i am starting an internship next month in one of the major banks as a student developer in my country and i like to have something to show and maybe continue to develop it with their help.
