RFID access controls are Broken. This $10 open-source device demonstrates how to break into buildings.

Are you the one who simply punch your wallet against a reader to get into your office? Then surely your office is using Radio-Frequency Identification (RFID) cards to manage building access and security.

However, these most common access control systems are incredibly easy to hack — and now more than ever before. Thanks to a $10 tiny device developed by two security researchers that can easily circumvent these RFID cards.

Dubbed BLEkey or Bluetooth Low Energy device is a tiny little device designed to be embedded in an RFID card reader, a small box you swipe or touch your card to open doors.

BLEkey exploits a vulnerability in the Wiegand communication protocol used by the majority of RFID card readers today in order to clone and skim your RFID-equipped cards.
