Customers will soon be able to use a cellphone at an ATM instead of reaching for a card.
The cardless technology has also been installed in a further 6,000 machines.

Authentication systems vary between banks and occasionally their branches. Citibank had previously tested an iris-scanner but dropped the plan after security concerns.
