I am trying to use a USB NFC card reader, ACR122U.
I managed to get the ID of the card by sending 0xFF, 0xCA, 0x00, 0x00, 0x00
and to tell the unit not to beep by sending control 0xFF, 0x00, 0x52, 0x00, 0x00
. However, using an Android app I wrote a URL to the cards first record (0).
Following the specs here, I should send 0xFF, 0xB2, 0x00, 0x08, 0x00
to read the first record, however I only get "c" as a response.
Does anyone have the actual command to send to get the first record?
Thanks!
