Visa Europe, Telefonica O2 and smart card manufacturer Giesecke & Devrient (G&D) are set to unveil a SIM card at Cartes 2009 which will allow for the transfer of a payment application from one mobile handset to another. The service uses Smart Card Web Server (SCWS) SIM cards provided by G&D, Telefonica O2 data communications and Visa Europe’s payment application. The technology will allow users to store all relevant payment and security credentials as well as the user interface in the SCWS SIM. This SIM can be taken out from one SCWS-enabled mobile handset and placed into another mobile handset supporting the technology, enabling users to continue using Visa payment services without the need to install a new user interface or payment application on the mobile handset when they change mobile phones. SCWS technology uses the SIM card as a local server inside the mobile phone to display a user interface to enable mobile payment services. It differs from JAVA application or localised software implementations of user interfaces by using standard internet technology such as HTML or Https secure connections. In order to present the content, the SCWS on the SIM connects to the internet browser of the mobile phone and offers the same look and feel as experienced on the internet.
