Royal Bank of Scotland Group is launching a mobile banking service that will allow 13 million customers to access their bank statements via mobile phone.
As well as using mobile phones to keep track of their money, the service will allow Royal Bank of Scotland and NatWest customers to top up mobile pre-pay phone and receive SMS balance alerts. In future, the service will also allow customers to make payments and move money between accounts.
The bank said the service would be secure as no data is held on the customer's phone, and only a handset that is linked to a customer's account can be used to access information.
The mobile banking application is the latest extension of Royal Bank of Scotland's e-commerce operation, following the issuing of card readers to its online banking customers to help prevent fraud.
The bank said the service will be available to all current and savings accounts which have a debit card. The software users have to install on their phones is free and there is no monthly fee, but there may be a data charge from some network operators.
The service will be provided by MoniLink, which is a joint venture between ATM operator VocaLink and mobile banking network Monitise.
Rival bank Barclays launched a similar mobile application in May, and other banks are expected to follow suit.
