Ever get tired of fumbling around your wallet looking for your room card key? Worse yet, to realize that you left the key in your room to begin with? What if you could control access to your room wirelessly? Now you can!
This remote keyless entry system consists of a wireless receiver mechanism that listens for passcodes sent by individual transmitter fobs. The transmitters send codes in encrypted form with a rolling code. This prevents any form of replay attack.
