Hey,
I had bought the flojack from you guys some time back, I am trying to build my application on them. If I am not wrong, they are same ones as ACR35.
I got the sdk from:
https://github.com/flomio/flomio_android/tree/master/ACR35

Having worked on ACR122U previously, I tried the same APDU commands for ACR35 as well. But am getting stuck at writing back on to my MIFARE Classic 1K card.

Commands I used:
For reading: FF B0 00 0C 10

I have a value block on my block no. ‘0D’. For adding and subtraction, I have an APDU for this purpose: FFD7000D0501000003e8, but for some reason, it is’nt working out on the flojack reader.

It would really help, if you could assist me.

Thanks in advance.
