Abstract: A vending system allows customers to interact with a vendor using their mobile device, without having any prior relationship with the vendor and without the vendor installing any custom payment hardware. With the ubiquitous nature of mobile devices, such as cell phones, and the access of nearly all vendors to the Internet, each party already has everything it needs to establish a payment relationship without custom hardware at the vendor. Customers also have no reason to wait for an employee to allow paying a bill, such as at a bar or restaurant, when the customer is ready to leave. The system can also be used for ordering without waiting for an employee of the vendor to take an order. Thus, the vending system allows vendors and customers to interact with much less friction, providing a faster and more pleasing experience for the customer without any downsides for the vendor.

Abstract: At least one contemporaneous signature image is captured while a user generates an electronic signature for a document. When one or more contemporaneous signature images maps to a verification image, signature data representative of an electronic signature is associated with the document.

Abstract: An advanced authentication system is described herein that applies technology only recently available to areas where the need for security and authentication is growing as well as to traditional areas. The system applies technologies that are substantially unique per individual, such as facial recognition and fingerprint readers. When a user attempts to access a target service secured by the advanced authentication system, the system identifies the user and receives information about the target service the user is trying to access. The system compares the user's identity and authentication information to the known group membership and stored authentication information. If the user is a member of the allowed group to access the target service, then the system allows the user to access the target service. Thus, the system allows people to have confidence in the services they use and can prevent catastrophic events where lax security is a contributing factor.
