What is a QR code?

A QR code is a two-dimensional code a phone camera can read. It may contain a website address, plain text or structured contact information. After scanning, the phone offers the relevant link or action. Common business uses include opening a restaurant menu, sharing a product guide and saving a professional contact. Choose one clear purpose so visitors understand what happens after scanning.

Choose the right type and check your data

QRCode.az supports URL, text, email, phone, WiFi, SMS and location codes. Use a URL for a website and the WiFi format for network details. Open the destination in a browser before generating the code. A customer-facing link should be publicly accessible rather than restricted to your own account. A QR code does not encrypt the information inside it, so do not include private data in public print materials.

Understand static and dynamic codes

A static code stores its content directly. Changing that content after printing generally requires a new code. A dynamic approach uses a managed link whose destination or content can be updated where supported. Updating products on an existing digital menu is one example. Check the behaviour of the selected tool instead of assuming every QR type can be edited in the same way.

Select an export format and test

Use a dark code on a light background and preserve the clear border. PNG is convenient for sharing; SVG preserves sharp edges when resized for print. If you add a logo, avoid covering too much of the code and test again. Scan with different phones. For print, test a sample at its actual size, distance and lighting before ordering the full batch. Start with a QRCode.az account and select the appropriate QR type.
