Checking the authenticity of a QR code is essential to ensure your security and privacy. With the rise of digital transactions and information sharing, QR codes have become ubiquitous. However, not all QR codes are safe, making it crucial to verify them before use.
What is a QR Code?
QR codes, short for Quick Response codes, are two-dimensional barcodes that store data, accessible via a smartphone camera. They are widely used for various purposes, including payments, website links, and product information. Understanding their function helps in identifying potential security threats.

-
Avoid Scanning Unknown Codes: Be cautious with codes in public places or from unknown sources. If a code seems out of place or suspicious, avoid scanning it.

Research the Source: If a QR code is linked to a business or event, verify its legitimacy through their official website or customer service.
