Abstract

A framework for point of sale system is discussed. The framework includes an application program stored on a tangible computer medium. When executed by a computing device, the application is capable of communicating using a first protocol. The framework further includes a first point of sale hardware device externally located from the computing device and configured to communicate with the computing device using a second protocol and a device abstraction layer capable of communicating with the application program using the first protocol and the first point of sale hardware device using the second protocol to pass information between the application program and the first point of sale hardware device.
