SEOUL -- Customers at a new 7-Eleven here can try their hand at using a self-checkout machine that lets them pay without cash or credit cards by scanning their veins for identity verification.
It is the first 7-Eleven in South Korea without any staff at its cash registers, according to Korea Seven, the operator of the convenience store. The shop opened its doors Tuesday on the 31st floor of a mixed-use highrise owned by South Korea's Lotte Group, the parent of Korea Seven.
All shoppers need is a Lotte membership card, which is used to enter the store and make purchases. Payments are completed automatically after the conveyor belt carries items through a scanner that can read bar codes from 360 degrees.
Meanwhile, store employees can concentrate on helping customers find items and stocking shelves. Korea Seven may also fly drones inside the shop to prevent theft.
In Japan, convenience stores chains such as Seven-Eleven and FamilyMart aim to introduce self-checkout machines at all of their locations by 2025.
