Just bought 2 xEM with the kit and a 532 reader/writer but the only cards I can read with it are the ones that came with the reader.
I have one card for a parking lot, one for the office and one for the gym, I can read all of them in all 3 places, actually bought a cheap usb reader that can read them without problem (but can’t read the ones that came with the 532)
I know all these cards are 125khz and the usb reader gives me codes like these:
The question is: How can I copy just one of these cards into the xEM ATA5577??
Will I Need a proxmark?
Is there something like the blue reader you used to sell that will work with these cards??
Your help is much appreciated before I stick this humongous needle in my hand
