![]() For example, if the QR code is 2” wide, the optimal scanning distance is 20” away. The optimal scanning distance from a QR code is a 10:1 ratio of distance to width. Test the QR code at different distances.Try to do so with as many devices and apps as possible. Scan and test your QR code in low-light, medium-light, and bright-light. Lighting is often inconsistent, whether that be due to the time of day or mood lighting. Test the QR code with various lighting levels.Do this with as many devices and apps as you can. Seek out any other popular third-party QR code scanner apps and scan your code with them. Download Google Lens and scan it with that. Use the built-in Camera apps on iPhone and Android devices. Scan the QR code with multiple devices and apps.If you test a QR code every way indicated below, you’ll remove a big portion of issues with scanning. Now let’s test a QR code online to account for the less-than-ideal circumstances. But what if nothing is showing up? What if the QR code doesn’t work? Here’s how to troubleshoot QR code scanning problems. Here’s far more in-depth instructions on how to scan a QR code. Asks you to choose a next step by giving you the option to visit the URL (if someone changed a URL to a QR code), copy or search text, or start a download.Redirects you to a URL (which can show a QR code PDF, text, images, or an HTML page).If your device does any of the following, it’s a valid QR code: Point your device at the QR code in question. Open up the built-in camera app or QR code scanner app on your device. The beauty of QR codes is that you’ll be able to automatically tell if it’s a valid code immediately upon scanning. Now let’s first test if the QR code actually has information encoded in it. How to Check If a QR Code WorksĬheck out our How Do QR Codes Work? post to familiarize yourself with their function. Then you need to test your QR code in different circumstances to account for any possible environmental problems. You need to know how to check if a QR code works in the first place. The first part of knowing how to run a QR test is knowing what success looks like. And finally, we have a QR code sample for testing at the bottom of the post. First we’ll test if the QR code works, then we’ll test that the QR code works in less-than-ideal conditions. So let’s go over how to run a QR code test. ![]() Knowing full well that when anyone scans it, it’ll run like a dream. Then, and only then, can you confidently blanket the world with your QR code. But, like any new feature or technology deployed, it must be rigorously tested to account for all possible points of failure. It’s much easier to scan a two-dimensional barcode like a QR code. What is a QR code? Well, QR codes are one of, if not the, easiest types of barcode to use. ![]()
