QR codes have become one of the most popular ways to access information. However, this technology poses significant risks regarding security and privacy.
A QR code (or Quick Response Code) is a technology that allows users to access information without the need to enter a browser or use a search engine. Users simply need to point their phone camera at a pre-set matrix of squares to receive the information they need.
QR codes are fast and facilitate easy communication. However, the technology carries many security risks. Users should avoid scanning codes from unknown sources to prevent data breaches or falling victim to malware.
4 Potential Risks When Scanning QR Codes
While QR codes have many uses and are beneficial, Make Use Of points out that the very nature of QR codes makes this technology susceptible to exploitation. Scanning codes from unreliable sources exposes users to various security threats.

Fraudsters can easily create QR codes, add the logos of app stores, and place them in crowded areas. Scanning these codes can trigger automatic features on the phone, such as downloading an app from a spoofed website. This can easily introduce malware onto the device without the user’s knowledge.
Additionally, fraudulent QR codes can lead to the loss of personal information and assets. These codes are created by hackers and link to fake banking or e-commerce websites. They closely mimic real websites, enticing victims to enter their email and password, thereby stealing their assets.
In 2022, Coinbase created a QR code offering a $10 cryptocurrency reward for anyone who scanned it, promoting it during the Super Bowl. Many scammers generated a similar code, displayed in videos to trick people into sending money.
Moreover, location tracking features can also be compromised, turning user data into a commodity for third-party companies. Some QR codes are designed to collect GPS information when users scan them. Customers’ privacy can be violated when their location is exposed.
The phone’s calling and messaging functions can also be activated through the action of scanning a QR code. This critical data can be easily collected by third-party companies.
Protecting Yourself When Scanning QR Codes
To avoid becoming a victim, users should refrain from scanning QR codes from unreliable sources or unofficial content on social media platforms. Additionally, security features and antivirus software should be enabled on smartphones. These tools can alert users when their device attempts to access a fraudulent website or block downloads of malicious apps.

Furthermore, enabling two-factor authentication is essential for all accounts. This setting adds an extra layer of protection against unauthorized access. This way, users remain safe even if they accidentally expose their email or important passwords.
On the other hand, disabling direct location sharing can also help limit the ability for devices to be tracked remotely. Turning off this feature prevents hackers from tracing users when they accidentally scan a QR code containing malware. The latest software versions of Android and iOS both offer options to provide approximate location data instead of the exact location from the device.
QR Codes Remain a Useful Technology
While not perfect, QR codes continue to be widely used due to their convenience.
With their square matrix, QR codes have advantages over traditional barcodes. Additionally, this technology allows them to function even when part of the code is damaged. When 30% of the code is obscured, it can still be used. Moreover, QR codes are not picky about scanning direction. Users can rotate their devices at various angles and still accurately retrieve the information they need.
