Comparison / QR code vs barcode
QR code vs barcode
They solve different problems. A linear barcode is a machine identifier read by dedicated scanners. A QR code is a data carrier read by the phone in your customer's hand.
The short answer
If a product passes through a retail till, it needs a linear barcode — UPC-A or EAN-13. No QR code substitutes for that, because point-of-sale systems look up a GTIN.
If you want a customer to reach a page, join a network or save a contact, use a QR code. It holds thousands of characters, survives damage through error correction, and scans from any orientation.
Most packaging ends up carrying both: a GS1 linear symbol for checkout and a QR code for the consumer. Keep them clearly separated so the checkout scanner never grabs the wrong one.
Side by side
| Criterion | Linear barcode | QR code |

| Orientation | Must cross the bars | Any angle |
| Damage tolerance | Low | Up to ~30% with level H |
| Retail checkout | Required (UPC-A / EAN-13) | Not used for POS lookup |
| Footprint | Wide and short | Square |
| Typical use | Product ID, SKU, logistics | URLs, Wi-Fi, contacts, menus |
Choose Linear barcode when
- The product is sold through retail checkout
- A warehouse or POS system looks up a fixed identifier
- You need the smallest possible vertical footprint
Choose QR code when
- A customer with a phone is the reader
- You need to carry a URL or multiple fields
- The label may get scuffed, creased or partly covered
