QR code scams are a type of scam that involves the use of QR codes to trick people into giving away their personal information. Scammers create fake QR codes that look like legitimate ones and place them in public places such as bus stops, train stations, and shopping malls. When people scan the code with their smartphone, they are taken to a fake website that looks like the real one. The website then asks for personal information such as credit card numbers, social security numbers, and passwords. Once the scammers have this information, they can use it to steal money or commit identity theft.
