How it works
• The NHS app has 10m users. It was launched in January 2019 as a handy way to book a GP visit, order a repeat prescription or view medical records.
• Earlier this year it was adapted to allow users to get their Covid vaccination certificate. Since May the number of users has grown by 6 million, driven by people’s need to display their vaccination status when crossing borders.
• The app asks all users to provide their name, email address, mobile number, NHS number, date of birth and postcode. However, to access the vaccine certificate and some other services users are asked for facial verification.
• The user submits a photo ID – either a driving licence or a passport – and then records a video of their face. The images from the video are compared with the photo ID, using technology provided by the London-based company iProov.
