QR Code Scams: A Comprehensive Guide to Understanding and Protecting Yourself


QR codes have become an integral part of our digital lives, offering a convenient way to access information, websites, and even facilitate payments. However, the increasing prevalence of QR codes has also given rise to a new form of online fraud: QR code scams. This article aims to educate teachers, students, and researchers about what QR code scams are, how they work, and how to protect oneself from falling victim to them.

What is a QR Code Scam?


A QR code scam is a type of online fraud where scammers use Quick Response (QR) codes to deceive people into visiting malicious websites, downloading malware, or divulging personal information.

Mechanism of Action

Scammers strategically place these QR codes in public spaces like posters, flyers, or even on products. They may also distribute these codes via emails, text messages, or social media platforms. When scanned, these QR codes redirect the user to a website or application controlled by the scammer, designed to look legitimate but with the intent to steal information or money.

How Do QR Code Scams Work?

Placement and Distribution

Scammers often place QR codes in high-traffic public areas or send them through various digital channels. The more people they can get to scan the code, the higher their chances of successfully scamming someone.

Redirection to Malicious Sites

Once scanned, the QR code redirects the user to a malicious website. These websites often mimic legitimate sites to trick the user into entering sensitive information.

Data and Financial Theft

The end goal is usually financial gain, either by stealing directly from bank accounts or by selling the gathered personal information on the dark web.

How to Protect Yourself from QR Code Scams

Be Cautious

Always be cautious when scanning QR codes from unknown or unsolicited sources.

Use a Secure QR Code Scanner

Opt for a QR code scanner that previews the URL before opening it, allowing you to verify its legitimacy.

Be Skeptical of Too-Good-to-Be-True Offers

If a QR code promises an unbelievable deal or discount, it’s likely a scam.

Avoid Financial Transactions

Refrain from scanning QR codes that are directly linked to financial transactions or require personal information.

What to Do If You’ve Been Scammed

Immediate Actions

  1. Contact your bank or credit card company to report the fraudulent activity.
  2. Change all your passwords, focusing first on financial accounts.
  3. Run a virus scan on your device.

Long-Term Measures

Consider placing a fraud alert on your credit report if you’ve divulged sensitive personal information.

FBI Advisory on QR Code Scams

In 2022, the FBI issued an advisory warning about the risks of QR code scams. The advisory echoes many of the protective measures mentioned above and emphasizes the importance of being cautious when scanning QR codes, especially those from unfamiliar sources.


QR code scams are a growing concern in the digital age. However, by being cautious and informed, you can protect yourself from falling victim to these scams. Teachers, students, and researchers should be especially vigilant, given their frequent use of digital resources.

By following the guidelines and tips outlined in this article, you can navigate the digital world more safely and securely.
