It works fine when I use PAX device.

I want to do the same as above but by use an android phone device that have nfc reader.

The scenario is, I communicate by desfire card with android library( in phone device and I communicate by sam card in PAX device and connect to device by a socket in network.

In PAX device give receive data to sam and get data from sam reader then Send them to phone device.
