An anonymous reader writes: MasterCard has announced plans to invest in facial recognition technology in the UK, in a push to reduce false decline transactions and increase security for mobile payments. Following trials in countries including the U.S. and the Netherlands, 'Selfie Pay' will be introduced in Britain this summer as part of the financial services company's identity validation process. Users will be able to choose between finger scanning and face recognition for verification, instead of traditional passwords or PIN numbers. Consumers will be asked to upload their pictures to be stored on MasterCard servers [paywalled]. These registered images will then be used as a reference every time a user opts for facial verification during a transaction.
