GS25 brings facial recognition to new shop — Korea JoongAng Daily — “Most convenience stores without a human cashier use barcodes to identify the products. GS25’s new system instead identifies an item by its packaging and weight. This allows customers to simply place items on the table before paying using facial recognition or a credit card. The company says it takes only about a second for the system to recognize five items at once, whereas with the conventional barcode system it would take 15 seconds to scan them one by one.”
