Barcode vs QR Code: Which Should You Use?
Published 9 October 2026
Barcodes and QR codes both turn information into a pattern a machine can read. They're not rivals though. Each is good at a different job. Here's how to pick.
| Barcode | QR code | |
|---|---|---|
| Shape | Lines of bars | Square grid |
| Holds | A short number or text | Links, contacts, Wi-Fi, long text |
| Read by | Shop and warehouse scanners | Any phone camera |
| Best for | Products, stock, shipping | Sending people online, sharing details |
The basic difference
A barcode is one-dimensional. The data runs along a single line of bars, so it holds a short number or a few characters. A QR code is two-dimensional. The data is in a square grid, so it can hold much more, such as a web address, a contact card or Wi-Fi details.
Side by side
- Capacity: a barcode holds a short number or text. A QR code holds hundreds or thousands of characters.
- Scanning: barcode scanners read bars from a line of sight. QR codes can be read from any angle, and by any phone camera.
- Who reads it: barcodes are read by shop and warehouse scanners built for the job. QR codes are read by ordinary phones.
- Size: a barcode is wide and short. A QR code is square, and handy where space is tight.
- What happens next: a barcode gives a number to a system, which looks up the details. A QR code can carry the details itself, or open a page.
When a barcode is the right choice
- Products sold in shops, which need an EAN-13 or UPC-A
- Stock control, shelves and warehouse locations, often with Code 128
- Cartons and cases, using ITF-14
- Anything where the person scanning has a dedicated scanner, and the system already expects a barcode
When a QR code is the right choice
- Sending people to a web page from print: flyers, menus, packaging, posters. Try a URL QR code.
- Sharing Wi-Fi, a contact card, an email or a WhatsApp chat
- Anything the public will scan with their own phone
Can you use both?
Yes, and many businesses do. A product might carry an EAN-13 for the till and a QR code that links to instructions or a support page. Just don't expect the till to read the QR code. Retail checkouts are set up for the barcode.
A simple way to decide
Ask who will scan it and what you want to happen. If a shop or warehouse system will scan it to look up a number, use a barcode. If a person will scan it with their phone to open something, use a QR code.
Make either one free: the barcode generator or the QR code generator.
A few real situations
- A market stall: put an EAN-13 on products only if a shop will stock them. For your own price tags, a Code 128 works. And a URL QR code on a sign sends people to your online shop.
- A café: a Wi-Fi QR code and a menu link. No barcodes needed.
- A warehouse: barcodes on shelves and cartons, because the staff use dedicated scanners.
- A freelancer: a vCard code on a business card.
Cost and tools
Both are free to make here. The difference is the equipment on the other end: a barcode needs a barcode scanner or a scanning app, while a QR code needs only a phone. If you want to try reading a code yourself, use the QR code scanner.

Frequently asked questions
Can a QR code replace a barcode on a product?
Not at the till. Shop scanners are set up for retail barcodes such as EAN-13 and UPC-A. A QR code can sit alongside it and link to extra information.
Which is easier to scan, a barcode or a QR code?
For phones, a QR code. For dedicated scanners in shops and warehouses, a barcode.
Can a barcode hold a web address?
Some formats can, but it's awkward and the code gets very wide. A QR code is the better tool for links.
Are barcodes or QR codes cheaper to print?
They cost the same to print. The deciding factor is who will scan them and what you want to happen.
