Camera's catching underage buyers

High tech face recognition cameras are being installed by a supermarket to stop kids buying alcohol and cigarettes.

Budgens are trying out the cameras at one of their big stores in London.

The machines scan your face as you are walking towards the till, it then gets checked against a database of youngsters who have been caught trying to buy fags and booze in the past.

If it recognise a face from the database it alerts the cashier so they know not to sell it to you.
