Key takeaways
- A QR code is a printed link any phone camera can open.
- Common business uses: Google reviews, menus, UPI payments, feedback, Wi-Fi and contact details.
- Dynamic codes can be repointed later; static codes can't.
- Print large enough, with strong contrast, and check codes regularly for tampering.
QR codes went from novelty to everyday tool — especially in India, where scanning a UPI QR code to pay is second nature. That familiarity makes QR codes one of the simplest ways to connect a physical space to something online: a review page, a menu, a payment or a feedback form.
What a QR code is
A QR (Quick Response) code is a square barcode that stores information — usually a web link. When someone points their phone camera at it, the phone offers to open that link. No app, no typing.
How businesses use QR codes
- Google reviews — open the review box directly, so happy customers can review in seconds.
- Menus and catalogues — share a menu or price list that you can update without reprinting.
- Payments — UPI QR codes let customers pay from any UPI app.
- Feedback — a short private survey for suggestions and complaints.
- Wi-Fi — join your guest network without typing a password.
- Contact details — save your phone, address and website in one scan.
- Social pages and WhatsApp — follow you or start a chat.
Static vs dynamic QR codes
A static code stores the final destination itself. It's free and permanent, but if the destination ever changes, every printed copy is wrong. A dynamic code stores a short link that forwards to the destination; you can change the destination later without reprinting, and most dynamic services show how many times each code is scanned. For anything printed in quantity — cards, stands, packaging — dynamic is usually worth it.
Designing and printing codes that scan
- Size: as a rough guide, at least 2–3 cm wide for close-up scanning; bigger for posters seen from a distance.
- Contrast: dark code on a light background. Light-on-dark and low-contrast colours fail more often.
- Quiet zone: keep a clear margin around the code.
- Keep the link short — shorter links make simpler, easier-to-scan codes.
- Add a clear call to action next to it: what will happen when they scan?
- Test the printed code on several phones before printing in bulk.
Where to put them
Put codes where people naturally pause: the counter, tables, waiting areas, receipts, packaging and doors. Avoid places people walk straight past or can't reach, and keep codes at a comfortable height.
Security: watch out for fake codes
QR codes themselves are safe, but criminals sometimes stick their own code over a genuine one — especially on payment codes — to send people to a fake page. Check your codes regularly, use tamper-evident placement (inside a stand or behind a laminate), and teach staff what your codes should open.
QR and NFC together
NFC lets people tap their phone instead of scanning. Putting both on the same card or stand means everyone has a way in — scanners and tappers alike.
The complete guide to NFC for businessFrequently asked questions
- Do customers need an app to scan a QR code?
- No. The built-in camera on modern Android phones and iPhones reads QR codes directly.
- What's the difference between a static and a dynamic QR code?
- A static code holds its destination permanently. A dynamic code points to a short link that forwards to the destination, so you can change where it goes — and usually see scan counts — without reprinting.
- Are QR codes safe?
- The code itself is harmless, but a scammer can stick a fake code over a real one. Check your printed codes regularly, and tell customers what the code should open.
uTapiT cards and stands combine a QR code with an NFC tap, and you can repoint them any time from your dashboard.
