This invention describes a method for a smartwatch to authorize mobile payments. When a payment request is received, the watch first checks if a paired mobile phone is nearby and in a trusted state, and if the watch itself is being worn. If any of these security conditions are not met, the watch prompts the user for a specific touch input, such as a gesture, to confirm and authorize the payment.
Why it matters: Filed before widespread secure payment systems on smartwatches. Today, advanced secure elements and robust inter-device communication make this approach more practical and secure.
