Financial transactional IC card reader (FINREAD) - Part 4: Architectural Overview

Scope

The goal of this document is to ensure that the design of a FINREAD card reader is capable of meeting the
requirements identified in the documents before. Further to this, to give the system a maintainable and flexible
structure that can easily incorporate changes in the demands and the necessary scalability to support a wide range
of applications.
This document is mainly based upon four main topics: a short introduction into the field of architecture for
IT devices; the physical architecture, which is more based on the different interfaces and hardware components
and the way they are connected ; the functional architecture, which mostly leads to a specific software
architecture ; and also to a specific information architecture and the necessary data structures that need to be
defined as part of an interoperable system design.
This document is an additional explanation for a potential developer - a guideline for how the defined functions
of the functional or security requirements should be implemented.
