Question How Do I Use a QR Code? Answer How do I scan QR codes? Most smartphones have built-in QR scanners, which are sometimes built in the camera. A QR scanner is simply a way to scan QR codes. Some tablets, such as the Apple iPad, have QR readers built into their cameras. Some older devices may require a particular app to read QR codes – these apps are readily available on the Apple App Store and Google Play. Scanning a QR code using your device is straightforward: Open the QR reader application or the camera on your smartphone. Point it at the QR code – you should be able to point your camera from any angle and still receive the necessary information. The data will be instantly shown on screen – for instance, if the QR code contains contact details, your phone should instantly download these.
