Scope:

This International Standard provides the specifications for the standard Open Terminal Architecture (OTA) kernel in several layers:

  •  definition of the virtual machine (VM);
  •  description of the services provided by the VM to terminal programmers;
  •  specification of a set of tokens representing the native machine language of the VM;
  •  specification of the format in which token modules are delivered to an OTA kernel for processing.


OTA defines a standard software kernel whose functions and programming interface are common across all terminal types. This kernel is based on a standard virtual machine, which is implemented on each CPU type and which provides drivers for the terminal's I/O and all low-level CPU-specific logical and arithmetic functions. High-level libraries, terminal programs and payment applications may be developed using these standard kernel functions.

Project need:

To review the Standard within the required 5 year period
