Frequently Asked Questions
Are QR codes safe?
QR code payments are generally very secure, as they use encryption and secure protocols. This protects sensitive data during transmission and prevents unauthorised access. However, users should avoid scanning QR codes from unknown sources, as they may contain malicious links or phishing attempts.
Why won’t the QR code scan?
It might be too dark. Make sure you’re in well-lit surroundings before you scan.
It might be dirty or damaged. Wipe it clean, or try a different QR code.
It’s too far away. Try zooming in on the QR code to make sure it’s in focus or aligned to the centre of your camera frame.
The QR code has expired. Dynamic QR codes can be set to expire, for example, when a limited offer has ended.
If you still have trouble scanning, then try asking the person or business who created it for a different QR code to scan.
How long do QR codes last?
Static QR codes can last forever, while dynamic QR codes may be set to expire, e.g. a train ticket valid for one day or a limited offer code.
Can I scan a QR code without an app?
Want to scan a QR code but don’t have a dedicated app? Both Android and iPhone offer built-in QR scanning. Open your Camera app. Aim the camera directly at the QR code, ensuring it’s centred and in focus. Wait a few seconds, and if your phone can scan the QR code, a notification will appear with options like “Open Website” or “Share link.” Tap the option you need.
How do I create a QR code myself?
Several apps, desktop tools, and online tools, such as QR Code Dynamic, can be used to create QR codes. Enter the information you want to store in the QR code, and then the tool will generate a scannable image to download and share.
How secure are QR codes?
QR codes are generally secure. However, it’s best to scan QR codes from trusted sources and avoid giving away personal information. Stay safe!
