Static and dynamic QR codes

Updated: 2026-10-11

Every QR code is a pattern of squares that holds some text. What matters is what that text is.

Static codes

A static code holds your details directly: your UPI payment link, your Wi-Fi password, or the full web address of your menu. When someone scans it, their phone reads the details from the pattern itself. Nothing in between can fail, track the scan, or be switched off. Every code on this site is static.

• Never expires and needs no account.
• Works even if the site that made it closes down.
• Nobody can quietly point it somewhere else.
• To change what it holds, you print a new one.

Dynamic codes

A dynamic code holds a short link to the QR company's own server, which then forwards the visitor to your real page. That lets the company count scans and lets you change the destination later. It also means your printed code depends on that company: many "free" QR sites stop forwarding after a trial and ask for a monthly fee, and the code on your shop board then opens an error or an advert.

Which is right for a shop?

For UPI payments, Wi-Fi, WhatsApp and contact cards, use a static code: the details rarely change, and a payment code should never pass through anyone else's server. For a menu or price list that changes every week, make a static code of a page you control (a Google Doc, your Instagram highlight, or your own website) and edit that page instead of the code.

Safety

Redirect links are popular with fraudsters because the code looks harmless while the destination can be changed after printing. A static code shows its real content when scanned: most phone cameras display the address or UPI name before opening it, so customers can see what they are about to open or pay.
