Younger drinkers in England and Wales will be able to prove their age with a digital ID starting this week as new laws give pubs, off-licences, nightclubs and restaurants the right to use biometric scanning technology to check customers are over 18.

Customers will be able to download software that scans their faces into their own phone to generate a QR code proving their age based on a stored proof of age. Other tech under consideration as part of the government push to digitise age verification for alcohol sales include a device which scans the veins in a drinker’s finger to verify their age. That system has not yet been approved for use.
