Abstract: When a merchant sells goods or services in a sales transaction, a merchant device can generate a bill. The bill includes an itemized list of the goods and services, a price for each item, and an identifier of the sales transaction. A first customer and a second customer split the bill using a first customer device and a second customer device, respectively. The first customer device establishes communication between the first customer device and the merchant device. Using the identifier of the sales transaction, the first customer device pays a portion of the itemized list of the goods and services at the merchant device. The second customer device establishes communication between the second customer device and the merchant device. Using the identifier, the second customer device pays a remaining portion of the itemized list of the goods and services at the merchant device.

Abstract: A system and method for providing a generic user interface testing framework, together with a mechanism such that libraries which are applicable to the desired application(s) can be qualified, and the test framework will load those libraries at execution time. With the ability to dynamically load only the desired libraries one is able to plug in new testing modules as needed, thus being able to accommodate new product qualification efforts with greater flexibility and efficiency.

Abstract: A system and method for providing a generic user interface testing framework. The test framework, together with the systems and methods embodying the technology, maps the native test development language and environment into arbitrary languages and environments. The generic UI test framework insulates test developers from learning the tool-specific scripting language and environment. In accordance with one embodiment, the UI test framework provides a set of function interfaces and implementations that cover all generic UI testing operations. New users need only map their testing logic to the supported library interface in order to use the test tool, or another test tool, without having to learn the details of the underlying test-tool-specific scripting language.
