US Patent 9172693 Quick payment using mobile device binding

Methods and systems are provided for secure device binding that provides user convenience through avoiding repetitive logging in when changing apps or moving from website to website. A mobile device undergoes binding to an account so that customers do not always have to enter their password when going through a financial transaction process, on a known (e.g., registered) mobile device. A device may be bound during an initial login, and once logged in, the user can select an option to be “remembered” so that the user need not re-login on the same device for future visits with an app or to a website that shares the service provider library.
