QR Codes Are Convenient, and Scammers Know It
QR codes became a normal part of daily life, especially after restaurants and businesses started using them for contactless menus and payments. Most people scan them without a second thought. Unfortunately, scammers have noticed this habit and are taking advantage of it.
How QR Code Scams Work
The most common trick is surprisingly simple: scammers print a fake QR code on a sticker and place it over a legitimate one. This has been reported on parking meters, restaurant tables, public bulletin boards, and even inside official-looking flyers.
When you scan the fake code, it takes you to a website that looks real but is designed to steal your payment information or login credentials. Some fake codes lead to downloads that install unwanted software on your phone.
Where to Be Cautious
Be extra careful with QR codes in these situations:
- Parking meters and public payment kiosks: Check whether the QR code looks like a sticker placed over something else.
- Unexpected emails or letters: If you receive a letter or email with a QR code asking you to verify your account or make a payment, go to the company's website directly instead.
- Flyers and posters in public places: Anyone can print and post a flyer with a malicious QR code.
How to Protect Yourself
A few simple habits can keep you safe:
- Preview the URL before opening it. Most phone cameras show the web address before you tap. Check that it matches what you would expect.
- Look for tampering. If a QR code looks like a sticker placed on top of another code, avoid scanning it.
- Go directly to the source. If a QR code is asking for payment or personal information, type the company's website address into your browser instead.
- Keep your phone updated. Software updates often improve your phone's ability to detect suspicious links.
Stay Curious, Not Fearful
QR codes are still a useful and generally safe technology. The key is to treat them the way you would treat a link in an email, with a moment of thought before you tap. A quick glance at the URL can save you a lot of trouble.
