Low power mode for payment transactions
First Claim
1. A method for operating a payment system of a computing device in a low power wallet mode, the method comprising:
- determining that a charge of a battery of the computing device is at or below a predetermined threshold, wherein the predetermined threshold is set below a minimum battery charge value for executing an operating system of the computing device;
in response to the determining, preventing multiple subsystems of the computing device from receiving power from the battery;
in response to the determining, providing a first power signal from the battery to a field detector of the payment system of the computing device; and
when the field detector indicates that a target system is at a sufficient distance to communicate with the field detector;
causing the payment system to provide an initiation signal to a power management system of the computing device, wherein the power management system causes a second power signal, that is greater than the first power signal, to be supplied to the field detector for conducting a payment transaction.

Abstract
This application relates to systems, methods, and apparatus for using a computing device to perform payment transactions while the computing device is operating in a low power wallet mode during a low battery state of the computing device. During a low power wallet mode, various subsystems are prevented from receiving current from a battery of the computing device, while a near field communication (NFC) system of the computing device is provided with an operating current for detecting target systems. A target system and the NFC system can communicate during the low power wallet mode of the computing device, thereby allowing a user of the computing device to conduct payment transactions when the computing device is in a low power wallet mode. Such payment transactions can be useful if the user is ever stranded without enough power to fully operate the computing device and needs to pay for transportation.
