Abstract

A system for enabling a service user to perform one or more transactions with the same or different service providers, while providing a high level of security for the performance of the transactions both with respect to the service provider and the service user, using an intelligent device. The system includes an intelligent device including a microcomputer having an input/output communication port, and microcomputer store including nonvolatile memory and random access memory. An interface device is associated with a memory for storing data and a coupler via which communications may be effected with the intelligent device. The store is arranged such that one part thereof has an operating system which can be run for performing basic functions of the device, the operating system being programmed in native code of the microcomputer. The random access memory is provided for use by the microcomputer when performing a function under the control of the operating system and for storing data received from or ready for transmission via the communication port. The interface device includes a program module within the memory including one or more instructions forming part of a prescribed instruction set discrete from the native code. The operating system includes a program interpreter for interpreting and executing the program module when the microcomputer is under the control of the operating system to perform a transaction in accordance with the instructions of the prescribed instructions set comprising the program module.
