NatWest has suspended its GetCash mobile app, which lets users withdraw money from ATMs without a card, after it emerged that thieves had defrauded some customers.
Launched in June, the 'GetCash' tool within the NatWest mobile app sends, upon request, a six digit PIN which can be entered at the bank's ATMs at any point within the next three hours to collect money.
Customers can ask for up to £100 at a time and make as many requests as they want in a day as long as they do not exceed their withdrawal limit.
Over the weekend, BBC Radio 4's Money Box programme revealed that the system has been used by thieves to steal hundreds of pounds from some customers.
One man spoken to by the programme had £950 taken from his account in 11 withdrawals over three days, despite not having signed up to the service. NatWest initially refused to refund the victim, accusing him of handing personal details to a phishing fraudster (the decision was overturned after Money Box contacted the bank).
Victims were told by NatWest that the service was being withdrawn although the bank told Money Box that it is only suspended for a "planned update" which will see the daily withdrawal limit cut.
