Face recognition in Missouri shop checks against watch list
15 February 2017
A network of shops in the U.S. state of Missouri have installed face recognition cameras that can detect if a shopper is wearing a mask or is a previous shoplifter. Developed by a local firm called Blue Line Technology, the cameras are linked to doors that will not open to either masked faces or known offenders. At night, clerks put up signs warning customers that facial recognition software is in use, and to please look at the above camera for entry. Only by showing your face will you get a green light to come inside.
