Royal Bank of Scotland has agreed a new five-year partnership with Monitise.
The deal involves the London technology firm providing secure mobile apps to RBS customers across all of its divisions including Citizens Bank, Natwest, Ulster Bank and global corporate business.
Will Jones, general manager for Monitise’s RBS partnership, said: "New apps have been developed on the Monitise platform as part of a partnership project with RBS called Quantum Leap.
"It really does deliver a leap forward in terms of client innovation and convenience, with helpful banking at the heart of these new apps.
"The integrated technology is fully flexible and lets the bank optimise every app to take advantage of what advanced handsets can do."
Alastair Lukies, group chief executive, said: "As a global provider of mobile money services we have great insights into the varied approaches being taken by banks and financial institutions around the world as they seek to defend and extend their business in this increasing digital and mobile age.
"RBS has positioned itself perfectly to embrace the mobile money evolution and we are delighted to be playing our part.
"Mobile, like any banking and payments ecosystem, needs to be easy-to-use, secure and interoperable and RBS are putting their customers first by recognising mobile as a channel in its own right, not just another access point for the internet or a call centre.
"There are 5.5 billion mobile phones globally and organisations that understand and utilise that channel best are going to get closer to their customers."
