System for authenticating a wearable device for transaction queuing

This invention describes a system that lets you pre-authenticate a wearable device, like a smartwatch, so you can make multiple purchases without repeatedly entering payment details. You set limits for the device, initiate a transaction at a terminal, and the system queues it. When you tap your wearable at the terminal, it sends a token to complete the purchase from the queue. The system can also suggest nearby terminals and process subsequent queued transactions automatically.
