గూగుల్ పే అప్ ని ప్లే స్టోర్ కి ఎప్పుడు విడుదలచేసింది?
In 2016, Google began a public trial in Silicon Valley of a related mobile app called Hands Free. In this system, the customer does not need to present a phone or card. Instead, a customer announces they wish to "pay with Google" and give their initials to the cashier, who verifies their identity with a photo previously uploaded to the system. The customer's phone will only authorize payment if its geographic location system indicates it is near a participating store.
