Greetings, lovely Medium readers! QR Codes have become increasingly ubiquitous in recent years, this rise in popularity is largely due to their versatility and ease of use in various applications, from marketing campaigns, and contactless payments, to digital menus in restaurants. However, safety concerns arise with the convenience of creating these codes using free online generators. In this post, we will explore whether free QR code generators are safe and what precautions you should take.
What Are QR Code Generators?
QR Code generators are online tools or software applications that allow users to create QR Codes tailored to specific needs.
