Use of wearable as an account control system

This invention describes a system that lets you control your financial or other user accounts using a wearable device, like a smartwatch. When you request an action, such as turning an account on or off or setting a spending limit, the system checks if you are actually wearing the device by analyzing sensor data like your movement or heart rate. If it confirms you're wearing it, the system allows the account operation, specifically focusing on a wearable paired with a mobile phone.
