Mastercard Wins Patent for Blockchain-based Coupon Authentication System

Financial services giant Mastercard has won a patent for a system that uses blockchain technology to authenticate coupons.

The patent, granted by the US Patent & Trademark Office (USPTO) on May 31, outlines a way for merchants to cut down on coupon fraud and more effectively issue targeted discounts to specific customers. The company first applied for the patent in Nov. 2016.

In one potential application of this system, an individual will be assigned a blockchain address, whose credentials will be stored in a payment instrument such as a credit card or digital wallet application.

When the user attempts to redeem a coupon, the point of sale device will interface with the private blockchain network to verify that the customer is authorized to receive the discount.

Following a successful transaction, the system will automatically transfer the coupon out of the customer’s wallet and into “burn address” or an address associated with invalidated coupons, preventing the user from attempting to redeem it multiple times.
