Separately, and earlier on in the week, Sainsbury's Bank customers were unable to use their credit and debit cards for a few hours on Wednesday following an unspecified technical glitch. Interestingly, Sainsbury's Bank was joint owned by Lloyds Banking Group (one of the legacy players) and was using its mainframe systems up until 2013, when it announced that it would buy out the Lloyds share and migrate all of its systems and processes to FIS in a major outsourcing deal – presumably in an attempt to modernise its services.
