A 'SCREENPHONE' banking service that interfaces with several leading retailers has been launched by Barclays Bank. The service is based on a larger version of an ordinary phone with a 8cm x 5cm integral screen. This enables users to access their Barclaycard and Barclays Bank accounts, plus a variety of other services including shopping, ticket purchasing, weather forecasts and local information. Participating retailers include Entertainment Express (part of Kingfisher), Victoria Wine, Ticketmaster and Scoot.
