Iris mobile NFC barcode ATM app

Citi tests ATMs that replace plastic cards with mobile phones, QR codes, NFC and iris scans (NFC World)

Customers using one of the new Irving ATMs download a mobile app and set up the transactions they wish to make when they reach the ATM on their mobile phone. They can then chose to have a QR code scanned by the ATM, tap their NFC phone against the ATM or have their iris scanned to authenticate themselves in order to complete the transaction they previously logged inside the mobile app.

This "grab bag" ID regime is interesting. Throw in Bluetooth, fingerprints, RFID and chip-on-card technology and the number of permutations of possible ID deployments goes up even higher. This is good news both for consumers and for business with ID management challenges.
