Abstract
The present invention describes a facility which may be used in conjunction with SmartCard technology. Application Protocol Data Units (APDUs) are used to communicate with SmartCards. The management of these units is the primary focus and advantage of this facility. Smartcard environments can require that the APDUs conform to an environment specific format, and they can have different methods of sending information to and from a SmartCard. Other tools exist which assist in creation of ADPUs for SmartCard communication, but they are most likely tied to a single SmartCard environment. Application Protocol Data Unit--Management Facility (AMF) has numerous advantages over other APDU generation tools and are described.
