This invention describes a system that lets you pre-authenticate a wearable device, like a smartwatch, to make multiple purchases without needing to re-authenticate each time. You set limits for its use, and when you want to buy something, the system puts the transaction in a queue. When you scan your wearable at a terminal, it uses a token to complete the queued transaction, and the system can even suggest other queued transactions on the terminal's screen.
Why it matters: When filed, wearable payment systems were nascent, and the infrastructure for seamless, multi-transaction pre-authentication and queuing was less developed. Today, widespread wearable adoption and improved POS integration make this system more feasible and user-friendly.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
