QR codes are not inherently dangerous. They’re effectively links we can click in the real world using the camera app on our phone. Like hyperlinks on a web page, QR code “links” can take you to good websites or bad websites. They can also disguise their ultimate destination by using URL shortening services like bitly or owly. But now “free” QR code generator websites – that is, sites that will let you create one of these QR codes by entering the HTTP link you want it to take people to – are using these redirects to basically hold your QR code for ransom. The QR codes they give you use the redirect links to insert themselves into the middle – and after some time, they will stop working until you subscribe and pay them money. If you’ve already printed these codes on hundreds of business cards or dozens of plaques for your restaurant, they they’ve really got you over a barrel. I’ll help you avoid these scams.
