Your phone’s built-in camera can make scanning a QR code straightforward, but decoding it quickly does not make its destination safe. Check the URL or action before proceeding, and treat requests for sign-in, payment, or access as decisions that need verification.
How do I scan a QR code with my iPhone or iPad?
Apple’s documented iPhone and iPad workflow uses the Camera app or Code Scanner. Point the device at the code, then review and tap the link that appears to open its content. Apple’s instruction is to “Hold your device so that the QR code appears, then tap the link to open the content.” Apple Support also describes adding Scan Code to Control Center and using the flashlight when the code is hard to see.

The camera recognizes the symbol and presents decoded content or an action. That can feel convenient because a separate scanner app may not be needed. It is not evidence that one phone scans faster than another: the cited guidance provides no controlled speed comparison, and the 2027 title should not be read as a claim about a new feature or measured improvement.
Is it safe to scan QR codes?
Scanning is not the same as trusting. A QR code can lead to a website, prompt an app download, or direct a payment. The FBI’s Internet Crime Complaint Center warns that criminals can tamper with physical or digital codes, redirect people to malicious sites, steal data, expose devices to malware, or divert payments. The Canadian Centre for Cyber Security also describes risks including cloned codes, malicious links, QR phishing (“quishing”), and unsafe third-party scanner apps.

These are risks to manage, not proof that every scan infects a device. The FBI/IC3 notes that most phones have a scanner built into the camera app and advises against downloading a scanner app prompted by a QR code. The Canadian Centre similarly recommends using the device’s camera or a secure code reader and avoiding unknown apps. Keep your device updated, and do not install an app simply because a scanned page tells you to.
How can I tell if a QR code is fake?
- Review the destination first. Check the URL displayed by your device before opening it. Look for misspellings or a domain that does not match the organization you expected. Do not enter credentials, personal information, or payment details on a page just because a QR code led there.
- Inspect the physical code. On a poster, menu, parking meter, or payment terminal, check for a sticker placed over the original code or other signs that it has been replaced. A code’s familiar placement or appearance does not verify its destination.
- Be cautious with unexpected codes. A code in an unsolicited message or an unexpected public placement may be part of a phishing attempt. If it requests a payment, verify the request through a trusted contact method rather than relying on the code or the message that delivered it.
- Confirm before proceeding. Where your scanner offers a setting to prevent automatic website opening, use it so you can review and confirm the destination first. Hong Kong’s government information-security guidance recommends this behavior for scanner apps; it is not a setting available in every built-in camera.
What if the QR code asks me to sign in or authorize a device?
Treat a sign-in or cross-device QR code as an authorization request, not just a link. RFC 10027, a 2026 best-current-practice document on cross-device flows, notes that a QR code or PIN may be transferred over an unauthenticated channel and that users can be manipulated about the context in which access is requested.

Before approving, verify which service is asking, which device or session is involved, and what access will be granted. If those details do not match the action you intended to take, stop. The QR image itself does not authenticate the request.
