Dozens of banks in the US are updating their ATMs, or installing new ones, in order to allow customers to withdraw cash without using bank cards. A new cardless system will be rolled out at around 2,000 cash machines across the US, operated by at least 28 banks, including giants like Wells Fargo, Bank of America and Chase. Under the new system, people can order cash on an app on their phone, and then scan a code at the ATM to receive their money, all without inserting a card or entering a PIN. The developers of the system insist that smartphone technology makes for faster and more secure transactions. More banks are expected to adopt the technology soon.
