I want a system to award online currency for client loyalty while I need a system for giving clients store credit when they sell their items to me. I think both can be served by giving clients barcodes on both plastic cards and .jpg attachments sent to their email addresses. These barcodes can be scanned by the clerk, who can then enter either the total sale for computing loyalty rewards or change in credit available as the client sells or buys an item. The barcodes are assigned randomly as then they can be given away immediately. When the card is given to the client, the client writes down their name, email address, and birthday. This data is later entered into the graph by a store employee next to each barcode. All other data is entered at the register. When the clerk scans the barcode, inputs the total sale or change in store credit and hits enter, the program displays either total loyalty points and loyalty points gained with current transaction or total store credit and store credit change with current transaction.
Specs are attached.
