Are you ready for 1bn mobile banking users by 2017

The 1 billion mobile banking user base represents over 15 percent of the estimated mobile subscriber base, so the big majority of users will still remain "unbanked", said Juniper.

The developed markets of the Far East & China, North America and Western Europe will have the highest penetration of users in 2017.

The Juniper "Mobile Banking: Handset & Tablet Market Strategies 2013-2017" report says that most banks have at least one mobile banking offering, either via messaging, mobile browser or an app-based service.

But a number of the larger banks are now "confidently deploying" two or more of these technologies together, particularly where there is significant smartphone and tablet penetration, said Juniper.

Juniper analyst Nitin Bhas said, "From the banks' perspective the triple play platform is advantageous as it avoids them having to switch suppliers for different approaches as well as maximising client reach."
