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 — 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 — runs entirely in your browser.
