Chances are, you've never thought about what's between your food and the QR code many restaurants force customers to use for access to their menu.

So, should you be concerned about using them? QR code menus were hardly seen until the COVID-19 pandemic but that's all changed. These codes are handy, you don't have to wait for a menu anymore and you don't have to touch them, either.

They're convenient for sure, but are there privacy concerns about using them? You bet. QR codes are used to link us to sophisticated systems that also take our orders and charge bills. In fact, a QR code can be programmed to link to anything.
