Daily Mail - Hi-tech face recognition cameras used in Budgens to spot underage drinkers
The Daily Mail reports: "The software takes measurements between key points on the face to make a template of a person's features that is stored as a 'token'. Customers' images are monitored and relayed to a control centre to be compared with under-18s already on record. Future options include other retailers linking the scheme to their shops to create a giant database."
