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

Citi has begun testing a screenless, cardless ATM concept developed by Diebold that lets customers make transactions using their mobile device instead of a plastic card and authenticate themselves using NFC, QR or an iris scan. 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.
