The service, available across hundreds of handset models, means Barclaycard customers can access their accounts, check their balance and view payment or transaction history at any time by simply accessing the site through their mobile browser. In addition, the site integrates with the Barclaycard Freedom loyalty scheme to provide access to the latest offers from nearby retailers, using the latest geo-location technology.

The specially optimized interface provides an effortless mobile web experience, which customers can access by using the same secure login details as their mybarclaycard account.

David Chan, CEO of Barclaycard Consumer Europe, said: "As payment experts, our role is to make it easier, more convenient and incredibly secure for people to manage their money while on the move. Many of our customers are time-poor or simply don't want to spend extra time on a PC checking their account. This mobile service allows our customers the flexibility and convenience to manage their finances whenever and wherever they choose".

"With consumers spending a quarter of their time online connected through mobiles*, providing a well designed service is essential to fulfilling our changing customer expectations. The service is a further realisation of Barclaycard's commitment to provide mainstream mobile banking services by 2012."
