Extended FAQ
When should I use a barcode vs a QR code?
Barcodes are better for short numeric IDs scanned by laser scanners (retail, warehouses). QR codes are better for arbitrary data, long URLs, and smartphone-based scanning.
Can I get a UPC for my product?
Yes β but you need to register with GS1 (the international body that issues product codes). EllyTools generates the visual barcode; the underlying number must be your registered UPC.
Are my codes stored?
No. The barcode is drawn in the page from the number you type, and the number is not sent anywhere.
