When it comes to cloning a card, in short, the IDs for the NFC part of this implant cannot be changed, the low frequency part can be but you will need a specific tool like the cloners sold at DT or the proxmark3. The proxmark is the best tool to use, but it’s expensive and a bit involved. If you go with the cloner be careful which one because some will set a password on the chip.
