Detect / Authorise / Decode the random generated UID #7

Passing (cardAid, cardUid, aesKey) generates a unique card ID each time, how can I determine this card belongs to which user/device. Reading the emulated card, I have a PN532 using the Adafruit library.

ryanhz commented 2 years ago

The reader should not read the card ID as the user identifier, although I know a lot of applications do.

braysonjohn148 commented 2 years ago

But HCE emulates the card ID only (cardAid, cardUid, [aesKey]). Where can I pass other details?

ryanhz commented 2 years ago

this code implement the P2P communication, so you can pass any data you want. the cardUid is send on the process command callback

Am sorry to be asking all these questions. But the android emulator emulates these (cardAid, cardUid, [aesKey]) where can I pass the other data? For example, I want to pass extra data like "HDHWHUD87346u3hbde" to the reader apart from the one above. Please you can explain more, am not an expert in NFC/HCE I just have this feature I have to implement.

i think you are looking something like this: https://github.com/ConorBobbleHat/AndroidNFCEmulator I had been able to read emulated NDEF record tag using PN532 + ESP8266 Arduino
