How it works

- Rob Davies

• 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.
