[NOISE] Bank of America wants to replace your physical wallet with a digital one. Instead of an ATM card you can use your phone to withdraw cash or check balances. So the first step is to access your digital wallet. [NOISE] You can do that with your fingerprint Connect that to the ATM machine and to your pin, as you traditionally would, and get your cash. The ATM uses the same NFC, or new field communication technology Found on some in-store registers. You can use most major digital wallets including Android, Apple, and Samsung Pay. It even works when you have no cellular connectivity. I took out cash several times at these ATMs, some using the cardless ATM functionality, and sometimes using a debit card. Turns out that using a phone definitely feels a lot quicker. If you lose your phone there are security measures in place. first is obviously, you know, the fingerprint. Second is the additional security on the ATM machine of having to use the PIN Two thousand four hundred machines across the US will have the technology in May and five thousand will have the feature by the end of 2016. This is not the first time we've seen a cardless way to take out cash. In Australia many bank apps let you generate a one time code and enter that at the ATM to withdraw money. Wells Fargo will deploy a similar code based system and cardless NFC access to over 40% of its ATMs by the end of 2016. Chase is also upgrading its ATMs to have the same cardless option.
