Work with QR Codes QR codes initially were used in the automotive industry to track vehicles during the production process. Today, QR codes often are used in publications and advertisements to convey information, direct users to a website, suggest users download a file, or direct users to an app store or marketplace to download an app. Exercise caution when scanning QR codes, because they may direct your mobile computer or device to a malicious website or file. For example, it probably is wise to avoid scanning QR codes appearing on homemade flyers and other similar sources. Scanning QR Codes When you encounter a QR code that you want to scan, you should use an app capable of reading QR codes. The following steps guide you through the process of scanning QR codes.
a. Download and install an app that can read QR codes.
b. When you see a QR code you want to scan, run the app on your mobile computer or device. If necessary, select the option to scan a QR code.
c. Hold the device still and point its camera toward the QR code to scan it.
d. Once your device scans the QR code, it will display the associated information. If the QR code represents a web address, the app will run a browser and navigate to that address. Generating QR Codes If you want to generate a QR code to make it easier for others to navigate to a particular location or perform an action, you should use a QR code generator. The following steps describe how to generate QR codes:
a. Use a search engine to locate a website that contains a QR code generator and then navigate to it. b. Enter the information, such as a web address, phone number, word, or short phrase, that you want the QR code to contain, and then tap or click the button to generate the QR code.
c. Copy the generated QR code image and then paste it in the desired location.
d. Scan the QR code to make sure it displays the results you expect
