During Google’s I/O developer event, Bank of America revealed its cardless ATM technology now supports Android Pay, as well as announcing the tech will be introduced to 5,000 ATMs in the US by year end.

The bank claims to be the first in the US to back a broad deployment of cardless ATM, which enables users with a smartphone to withdraw cash, make transfers and check balances.  Bank of America introduced those features to select ATMs in a number of cities earlier this year.

The news was announced on stage by Michelle Moore, the bank’s head of digital banking, and Pali Bhat, Google’s senior director of Android Pay.

A wider roll-out will start this month with the technology’s introduction to 2,400 ATMs across the US, including the majority in the San Francisco Bay and Silicon Valley areas.

The technology works by the bank’s customers choosing their Bank of America debit card in the wallet on their smartphone and then holding the device over the ATM’s contactless card reader. Then they follow the normal process with their PIN, select their account and carry out a withdrawal, transfer or balance enquiry.

The cardless ATMs support mobile wallets that are enabled with near field communications and loaded with a Bank of America debit card.

Bank of America, as well as Wells Fargo, were working on Apple Pay integration for their ATMs, Techcrunch reported earlier this year, but nothing was subsequently confirmed. At that time, Wells Fargo already supported Android Pay.
