Bank of America said 126 of its ATMs in the Chicago area soon will be converted into ones where customers will be able to withdraw cash using their smartphones. The bank has decided to expand cardless technology for 5,000 of its ATMs – or about a third of its cash-dispensing fleet – by year end. The technology went live in the San Francisco area and will roll out to 2,400 ATMs nationwide this month, including the majority of ATMs in the San Francisco area and the 126 in the Chicago area. The technology enables customers to withdraw cash, make transfers and check balances using a digital wallet stored on their smartphones. Customers can identify cardless-enabled ATMs by the contactless symbol near the card reader. When ready to make a transaction, customers select the Bank of America debit card in their digital wallets and hold their devices over the ATM’s contactless card reader to activate the ATM. Then they follow the normal process to enter a PIN on the ATM, select an account and initiate a withdrawal, transfer, or balance inquiry.
