The app – which will help the 10,000 of customers who have some form of visual impairment – is the first ever to be accredited by the Royal National Institute of Blind People.
More than 160 changes have been made to the app, which is available to customers on iPhone or Android.
Steve Tyler, head of solutions, strategy and planning at RNIB said: “This new app provides customers with access to their bank account via a mobile. It’s a service that is available to all their customers, but has been tested to ensure that it is easy to use by blind and partially sighted people.
“The app offers lots of benefits including transferring money between accounts, making payments, fingerprint login – on the iPhone – and the “get cash” feature whereby the user is sent a code which is then inputted into an ATM in order to get cash out .
“What’s also great is that blind and partially sighted people have access to the same app as their sighted peers, at the same time.
“RNIB are excited by this new offer, and delighted that NatWest is continuing to work towards providing accessibility for all.”
People who use Android phones will now also be able to use fingerprint authentication to log-in to their mobile app, a first for a UK bank. This removes the need to remember a passcode.
