Derawi Biometrics and Heiko Witte with in cooperation with the Electrical Department of Gjøvik University College, have developed a first prototype that opens a door with your smart-phone by taking a picture of your finger (fingerprint-recognition) or even by walking to the door (gait-recognition).
The technology used is Near-Field Communication and the devices used are a Samsung Nexus S phone and an NFC (ACR-122) reader. Implementation details of both the client and the phone can be found in Heiko Witte´s Blog.
