The Japanese technological conglomerate Hitachi together with the telecommunications giant KDDI started testing of a blockchain of retail payments verified by the user's fingerprint. This is reported by CoinDesk.
It is reported that the complex, created on the basis of the development of the Hyperledger Fabric start-up, is integrated with Hitachi's biometric verification technology and the KDDI coupon system. So, users can use coupons, pay for services and verify payments using a fingerprint scanner.
As representatives of Hitachi explain, a user needs to register a coupon and verify himself using biometric information. The store will act as a blockchain node and will be able to verify the identity of the buyer with the help of a fingerprint.
As a result, users can authenticate themselves by holding the finger on the authentication infrastructure, so it is not necessary to present a coupon at the store, and the coupon can be used even without a smartphone.
Representatives of Hitachi emphasize that using the technology of the distributed ledger will help instantly spread the information about the used or appeared coupon.
