Cloning of RFID cards
Cloning of RFID cards
Is it possible to clone a card, if the antenna is damaged ?
Totally agree with @expert_sg and @nayakp. Regarding cloning it depends on the card and its security. For example, if you are talking about a 125KHz proximity card, there is literally no security or keys and can easily be cloned. If you take Mifare Classic, it has only 6 bytes key with Crypto1 algorithm and pretty easy to clone for an expert. And if you consider, for example Desfire EV2/EV3 or Cipurse, this is little more advanced and supports AES keys and advanced security featues and little hard to clone
If you’re able to clone cards before the antenna is damaged, then you can do the same after also replacing the antenna. The IC comes with LA and LB pins to connect the antenna. You can connect the new antenna to these pins if you have infrastructure to do so. If your question is towards destroying cards, then punch the IC not antenna.
The antenna is a wireless transmission medium. Clone of a card depends on the hardware and software implementation on the IC (chip). might be possible to clone if the chip has known/unknown vulnerabilites.
