RBS and NatWest customers will be the first of any UK-based bank to be able to log in to their mobile banking app using only their fingerprint.

Customers who have an iPhone 5S, iPhone6 and iPhone 6+ will be able to access their mobile banking app using Apple’s Touch ID fingerprint sensor. The technology recognises the customer’s unique fingerprint, meaning they don’t have to remember a passcode.

RBS and NatWest have introduced Touch ID following feedback from their customers, who took to the banks’ online community forum ‘Ideas Bank’ to ask for this latest technology in their mobile banking app.

More and more of RBS and NatWest’s customers are using digital technology to bank. Nearly 50% of the banks’ 15m customers actively use online banking, with over 3m customers using the mobile app every week. RBS and NatWest have 1.8m active iPhone users, of which 880k use an iPhone 5s, iPhone 6 and iPhone 6 plus.

NatWest and RBS’ busiest branch is the mobile app itself – over 167,000 of RBS and NatWest’s customers use it between 7am and 8am on their commute to work every day.

Stuart Haire, managing director of RBS and NatWest Direct Bank, said: “There has been a revolution in banking, as more and more of our customers are using digital technology to bank with us. Adding Touch ID to our mobile banking app makes it even easier and more convenient for customers to manage their finances on the move and directly responds to their requests.

“Our aim is to be the number one bank for customer trust, service and advocacy so we want to continue adapting our service based on the valuable feedback we receive from our customers every day.”
