4. Don’t trust a QR code that has been emailed by a friend (whose account may have been hacked) or appeared in a text, online post, or email. Instead, use a browser and visit a website using a domain name that you know is legitimate.
5. Avoid using a QR code to pay a bill. There are many other payment methods that are less susceptible to fraud.
6. QR codes may appear harmless, especially because the naked eye cannot detect what the codes are programmed for. So trust your instincts, advises Kitten. “If the code is stuck on the side of a towel dispenser and looks suspicious, don’t use it. Ask for a menu. “
7. Consider adding protection that checks for malicious or inappropriate content, advises Grant, who says many companies, including Sophos Mobile Security and Kaspersky, offer mobile products.
QR codes can be useful
The bottom line: QR codes can be created quickly and easily, but like other tech tools hijacked by scammers, they also serve a legitimate purpose in commerce and everyday life.
A few of his friends, Grant explains, use QR code generators to share their Wi-Fi passwords with guests, “because when their kids ‘friends come over to their house, they’re always like,’ Hey, what is your wi-fi? “
“So now when their children’s friends come they go to the refrigerator [where the QR code is placed] and now they’re on home Wi-Fi without having to disturb parents all the time. “
