Japanese telecommunications operator KDDI is introducing an in-store coupon pilot program that will give customers an easy way to access discounts.

The blockchain coupon is designed to securely record information and prevent it from being tampered with. When it comes time to redeem the coupon in a store setting, a user is able to authenticate themselves just by having their finger scanned to verify that the biometric information matches what's stored on the infrastructure. As such, there is no need for a customer to present a physical coupon in-store or call up the coupon on a mobile device.

The innovative coupon system offers other advantages for businesses as well, namely the fact that data can be shared safely between the carrier and affiliated stores.
