Abstract: A system and method for managing one or more applications deployed on a mobile electronic device, such as a cellular phone, are disclosed. The system and method enable the user of a mobile electronic device to select one of a plurality of applications deployed on the mobile electronic device for use in a transaction and to authenticate himself or herself prior to initiating the transaction. The transaction may occur via a wireless interface and/or a contact-based interface. In addition, the system and method allow the user to manage applications deployed on a mobile electronic device, including adding new applications, designating nicknames for the applications and setting security codes for each application.

Abstract: A terminal software architecture accepts a card that implements a card application of a merchant. A terminal application is developed independently of the terminal. The terminal has an environment component including terminal hardware, an operating system, and an environment services layer that supplies one or more environment dependent services that are dependent upon at least one of the operating system and the hardware of the terminal. The terminal application is compatible with the card application and has a platform independent portion that is independent of the environment component and a business logic layer that implements business policies associated with the terminal. The business logic layer makes calls to the terminal application through an access module and an application programming interface. The terminal application makes calls to the environment services layer through an access module and an application programming interface.

Abstract: Methods and apparatus for implementing a terminal software architecture for accepting a card that implements a card application of a merchant are disclosed. The terminal comprises an environment component including hardware of the terminal, an operating system of the terminal, and an environment services layer that supplies one or more environment dependent services dependent upon at least one of the operating system and the hardware of the terminal. The terminal further comprises a terminal application compatible with the card application and having a platform independent portion that is independent of the environment component.
