A new kitemark has been launched to help people identify apps and websites they can trust with their personal and financial details.
Barclays' Pingit mobile payment service and Barclays Mobile Banking are the first products to have been independently assessed in order to be awarded the new BSI (British Standards Institution) kitemark for secure digital transactions.
Although the kitemark is initially being piloted within the banking industry, the BSI envisages that its use will be adopted by a wider range of firms - for example within the entertainment industry.
Producers of websites or apps which want to achieve the kitemark will need to undergo "rigorous" testing to make sure their security controls meet the required standards for handling confidential data, the BSI said.
Those that meet the standards will be able to give customers confidence by displaying the kitemark on their products and in their marketing materials.
