Converting serial data to Ethernet in a supermarket chain

A supermarket chain is remodeling all its stores. It is a good opportunity to do something with the problem of outdated barcode printers and scanners. This equipment cannot be connected to a network; as a consequence, the supermarket relies on printed receipts and scanned barcodes are not stored anywhere. To fix that, data from the serial line need to be transferred over the Ethernet.

Issues:

• Data on printed receipts only
• Further processing impossible
• Environmentally unfriendly solution
