What can you use a QR code for?

QR codes have moved far beyond restaurant menus. Businesses print them on packaging to link straight to product pages, event organizers use them for instant check-in, and freelancers add them to business cards so a single scan saves a contact or opens a portfolio. The Wi-Fi and Contact Card generators above skip manual typing entirely — a guest scans once and connects or saves your details automatically.

Common uses include linking to a website, sharing Wi-Fi credentials without reading out a password, sharing a digital business card at events, or verifying a code someone else printed using the scanner tab.

Tips for a QR code that scans reliably

Keep enough contrast between the code and background colors — dark code on a light background scans fastest, especially from a distance or under bad lighting. If you add a logo, keep it small relative to the code; a logo covering too much of the center can make the code unreadable. For print use, generate at 300px and avoid placing the code smaller than roughly 2×2 cm.

Frequently Asked Questions

Is this QR toolkit really free?
Yes — generating, adding a logo, and scanning are all free, with no sign-up and no limit on how many codes you create.
Is my Wi-Fi password or contact info sent anywhere?
No. Every code is generated locally in your browser using JavaScript. Nothing you type is uploaded to a server or stored by ShokokoTech.
Will the Wi-Fi QR code work on both Android and iPhone?
Yes. Both Android and iOS camera apps recognize the Wi-Fi QR format used here and will prompt to join the network directly after scanning.
How does the scanner read a QR code from an uploaded image?
The scanner analyzes the pixels of the image you upload directly in your browser to detect and decode the QR pattern — no image is sent to any server.
