The document discusses using remote point-of-sale (POS) technology to integrate self-checkout (SCO) solutions into existing retail systems. It describes how a "Remote POS" component can control the transaction workflow for a SCO lane while leveraging the existing retail POS for the rest of the functionality. The integration would allow retailers to offer complete SCO solutions using their current POS systems. It also mentions tools used for the application development including Eclipse, RAD, and Rational Software Architect.
