This document describes the software requirements for an Automated Teller Machine (ATM) network. It is intended for the designer, developer and maintainer of the ATM. These are intended mainly for reference by people involved with the projects on a day to day basis, rather than as a general overview. The hardware, software and protocols described in these documents are all under active development.
