Understanding QR Codes
QR codes are two-dimensional barcodes that encode information such as URLs, text, contact details, or other data. They consist of black squares arranged on a white background in a grid pattern, with a distinctive square pattern in three of the corners. Scanning a QR code using a smartphone camera or QR code scanning app allows the encoded information to be extracted and acted upon.

Potential Risks of Scanning QR Codes
While QR codes offer convenience and efficiency, they can also pose security risks if any malicious actor has altered the QR Code. A QR Code can open any application or even initiate a phone call. Scanning a malicious QR code can lead to the automatic download and installation of malware or malicious software onto your smartphone, compromising its security and privacy.
QR codes may redirect users to phishing websites or counterfeit pages designed to steal personal information, credentials, or financial details through deceptive means. QR codes can be abused to collect sensitive information such as contact details, location data, or payment credentials by landing to a fake website, which may be accessed by innocent parties if scanned without proper precautions.
As for monetary transactions, you may think to avoid scanning merchant’s QR Code sticker or advert, instead ask the account details of the merchant and manually type it.

Safety Considerations for Scanning QR Codes
To mitigate the risks associated with scanning QR codes, consider the following safety measures:

- Before scanning a QR code that redirects to a website, manually verify the URL by typing it into your web browser or using a URL scanning service to check for any signs of phishing or malicious activity.
- Exercise caution when scanning QR codes for payment transactions, especially from unfamiliar vendors or merchants. Verify the legitimacy of the payment platform and ensure that the transaction is secure before proceeding.
- Use reputable QR code scanning apps or built-in smartphone features that prioritize security and privacy. Look for apps with robust security features, such as QR code validation, URL scanning, and malware detection capabilities.
- Ensure that your smartphone operating system, QR code scanning apps, and security software are up-to-date with the latest patches and security updates to protect against known vulnerabilities and exploits.
