This invention describes a system for buying physical items using a mobile phone and special low-cost tags. These tags, made from materials like paper or plastic, are affixed to objects and contain a unique code. A customer scans the tag with their phone to complete a purchase, bypassing traditional checkout systems. The patent's claims specifically detail a method for creating these tags in booklets, each tag having unique identifiers and a proof of payment number, which are then linked to product pricing in a central database.
Why it matters: Filed before the widespread consumer adoption of QR code payments and the maturation of cloud-based payment processing platforms. Building the "tag service provider database" and integrating payment systems, as described in the claims, is now significantly easier and more cost-effective.
