A Japanese security service company claims it is about to revolutionize the safety of store workers with a new system that will bring immediate help if thieves strike, according to the Nikkei Weekly. Sogo Keibi Hosho Co has worked with domestic point-of-sale system maker, Tec Corp and Toshiba Corp to perfect the hardware. The system establishes a link between its operations center and cash registers in convenience stores. Sensors attached to the register can sense abnormal use and an alert is then relayed by lines that are undetectable to the thief, to the control center. The system can also be triggered manually by an alert button. Sogo Keibi Hosho plans to start offering the service in October, priced at around $54.
