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!

You have to use the .Transmit() method instead of the .Control() method.
