While it’s unlikely that fraudsters will have replaced all the QR codes on the menus at your local restaurant, a code randomly stuck to a wall in a public space is more likely to be risky. But it’s still worth being cautious when scanning QR codes in public places, especially when you’re not sure who’s behind them. As long as your device is running up-to-date software, it should be able to spot and block these malicious techniques. There is potential for abuse from shady operators, mainly through attempts to send you to websites designed to capture login details or install malware on your phone. This technology can be really useful, but don’t go down the street scanning every QR code you find. This means angles aren’t usually a problem, and you won’t need to get the framing exactly right or have a perfectly steady hand. The three black squares in the corners of the graphic tell your phone where the code is, before the actual scanning takes place. You might be surprised at how easily your phone can read QR codes. This means these patterns can contain significantly more information-just about any type of data, and up to about 4,000 characters of text. But your phone can read QR codes in two directions: top to bottom, and left to right. Scanners can only read standard barcodes in one direction, top to bottom. In the same way that a store checks barcodes to identify the prices of various goods, you can scan a QR code to launch a website, register at a doctor’s office, sign into a service, get a Wi-Fi password, or install an app. They’re essentially a type of code that holds information in a form that other hardware and software can understand. While you might have only heard about them recently, this technology has been around since the 1990s.
