The service will be the first of its kind in Japan, Matsuhashi said. The bank, a unit of Seven-Eleven Japan parent Seven & i Holdings, initially will limit the use of facial recognition to its roughly 2.75 million account holders. The service could be expanded to depositors at other institutions. Seven Bank ATMs are located in Seven-Eleven convenience stores throughout Japan. To activate facial recognition, customers will link their account information to their faces at a Seven Bank ATM. Those customers then receive a unique ID, required in subsequent transactions as an added security measure. They no longer will have to present their cash card to the machines. Around 13,000 -- or half -- of Seven Bank's ATMs already carry facial recognition technology. Another 6,000 machines are slated to be replaced this fiscal year with the updated model, developed jointly with Japanese technology company NEC in 2019, in preparation for the new service.
