QR codes are everywhere—on cereal boxes, menus, store signs, and billboards. They offer quick access to websites, promotions, and payments, but do you know what’s behind those QR codes you’re scanning?
For most of us, the answer is no. And that’s a problem. QR codes can conceal significant security risks, leaving your device and sensitive data vulnerable to cyberattacks.
At Payments Guardian, we understand how external threats, including those hidden in QR codes, can impact your business and customers. That’s why our platform includes built-in safeguards to defend against potential client-side attacks, ensuring you and your customers are protected.
Here’s everything you need to know about QR codes, the associated risks, and how Payments Guardian’s innovative approach makes transactions safer.
What Are QR Codes?
A QR (Quick Response) code is a square, black-and-white pattern that can be scanned with a smartphone or camera to transfer data. Initially created in Japan to track public transportation, QR codes appear in nearly every aspect of daily life.
There are two types of QR codes:
Static codes: Pre-printed and unchangeable, often found on product labels or advertisements.
Dynamic codes: Editable codes allow businesses to update the linked information as needed.
While QR codes are incredibly versatile, this adaptability also makes them a target for cybercriminals.
Why Are QR Codes Risky?
Although QR codes themselves are not inherently dangerous, they can be misused in several ways:
Malware installation: Redirecting users to malicious websites or downloading harmful software.
Data theft: Capturing sensitive information like login credentials or credit card numbers.
Device hijacking: Exploiting access to your camera, microphone, or other functions.
Their ubiquity makes them particularly risky—people routinely scan them without questioning their origin or safety.
What Makes QR Codes Vulnerable?
Easy to counterfeit: Fraudsters can overlay malicious QR codes on legitimate ones.
Distance scanning: QR codes can be scanned from a distance, making them accessible to unintended users.
Untraceable links: Shortened URLs or hidden redirections make it hard to identify malicious intent.
How Payments Guardian Mitigates Risks
Payments Guardian defends against potential client-side attacks, including those facilitated by QR codes. Here’s how:
