QR code scanner
Scan a QR code with your camera, or upload a photo or screenshot. We show you exactly what is inside, check where links really go, and warn you about fake UPI payment codes. Nothing opens until you choose.
The camera is used only while you scan. Video and images stay on your device: the code is read in your browser.
How to scan a QR code online
- Tap “Scan with camera” and allow camera access, or upload a photo or screenshot.
- Hold the QR code inside the frame. It is read automatically.
- Check what the code contains. For links, read the safety check before you open them.
How to spot a QR code scam
- Scanning is only for paying. Nobody needs your PIN to send you money.
- Before entering your PIN, check the name your UPI app shows.
- Watch for QR stickers pasted over the real one at shops, parking and petrol pumps.
- A link that asks for an OTP, card details or a “KYC update” is almost always a scam.
Questions
Is this scanner free and private?
Yes. The code is read in your browser: camera video and images are never uploaded. Only when the code holds a link do we send that link to our server, to follow its redirects and check it for warning signs.
Why does the camera not open?
Your browser must allow the camera for hi4.in. If you blocked it, tap the lock icon next to the address, set Camera to Allow and reload. You can always upload a screenshot instead.
Can it read a QR code from a screenshot or WhatsApp image?
Yes. Upload the image, or paste it on a computer. If it fails, crop the image closer to the code and make sure it is sharp.
Does “No warning signs found” mean a link is safe?
Not always. It means our checks found nothing suspicious. Still never share an OTP, PIN or card details because a link or QR asked for them.
