In this digital age, QR codes have become ubiquitous, seamlessly linking the physical and digital worlds. While most people are familiar with scanning QR codes using their smartphones, fewer know how to utilize them on a laptop. This article aims to provide a comprehensive guide on how to effectively use QR codes on your laptop, covering everything from generating codes to scanning them and understanding their application.

Risks of Unknown QR Codes
Scanners can be tricked into visiting malicious sites, so avoid scanning QR codes from dubious sources. Often, scammers use fake QR codes in public places. Always verify the source before scanning.
Securing Your QR Code Information
