This is a fairly basic barcode scanner catalogger thing, probably the first of its kind here on Scratch, as not many people own barcode scanners. It isn't optimized either but its so simple it doesn't really need any optimization. The max limit of catalogged barcodes is 100,000. 1. Asks you if you want to reset your catalog. Do this if you're leaving the project or if its your first time. 2. You're given 3 options 2A. ADD a barcode with a description, category, and price. 2B. SCANLIST for a barcode, if you've already added the barcode to the catalog with the ADD function earlier. 2C REMOVE a barcode and its description, category, and price. 3. Follow the instructions given by the text bubble if necessary.
Please do not scan any barcodes that are on personal items. I trust Scratch but maintaining privacy is important.
