The Application Development Kit (ADK) is a collection of system components that provide a set of functions that can be used to build a payment application.
All components are intended to run under VOS1, VOS2, and VOS3 - a Verifone operation system, providing the same public APIs for all platforms.
This ADK Programmer's Guide provides a description of each ADK component, a collection of component-related public APIs, system architecture, maintenance, and troubleshooting guides.
