So what exactly is a proximity card? Let’s take a look inside!Ī prox card can basically be divided into three components: a coil, a capacitor, and an integrated circuit. Proximity cards use 125 kHz radio frequency fields to communicate when in close “proximity” to a reader, hence the name. Because there are many different types of card technology today, we will refer to the vulnerable type of cards as “proximity cards.” So if someone wants to clone an rfid key card, it’s not actually hard thing to do. If you think that these cards are “safe” or “secure” or “impossible to hack,” you would be wrong. Yes, the white card you were assigned when you started working in an office building. One of the most commonly used technologies in the security industry is easier and cheaper to clone than you would ever imagine.
Please do not use the following information on how to clone an rfid key card to exploit someone else’s security system or to try to gain access to unauthorized facilities. We are able to do this by educating the public on security threats and possible vulnerabilities.
