Starbucks says it would allow its customers in the United States to earn and purchase digital collector stamps in the form of nonfungible tokens, or NFTs. Each collectable digital stamp, dubbed "Starbucks Odyssey," will have its ownership validated on the blockchain and will carry a point value depending on its rarity. Members' points will rise as they collect more stamps, giving them access to exclusive activities. Starbucks claims the incentives range from a virtual espresso martini-making workshop to access to special event invites at Starbucks Reserve Roasteries and even excursions to the Starbucks Hacienda Alsacia coffee plantation in Costa Rica.

NFTs may be earned by playing interactive coffee-themed games or completing interesting tasks on Starbucks Odyssey, which will be available later this year. Users may also buy NFTs on the built-in marketplace without connecting their wallets or using any crypto. All stamps will have classic Starbucks artwork made in collaboration with Starbucks partners and outside artists. A part of the revenue from the sale of limited-edition stamps will be given to the causes of the designers. The NFTs itself are produced on Polygon's proof-of-stake blockchain.
