Near Field Communication or NFC is a short-range communication channel that is one of the most promising technologies around. One of the purposes for this technology is to simplify first-time connections to other wireless technologies, like Wi-Fi and Bluetooth. In this article we will show how Near Field Communication in a Samsung Nexus S smartphone can be used as part of a two-factor access control system for unlocking a door. Biometric Fingerprint recognition is used for authentication and NFC will be used to transmit authentication information to computer controlling the door. We will define some requirements for the system to increase security and propose some solutions for implementation to improve protection of biometric assets.
