I am trying everything to read a serial id with a mifare card. I can use the atr from pyscard. But he will give the same id when i am using mulitiple cards.
Or do i write data on a mifare card. But how can i do this. I am useing the python script on a ubuntu server. My cardreader is a acr122u.
Please it will be very helpful
Thanks
The best way to use is pyscard (Python module) or Java Smart Card I/O (part of Java JDK)
