What is a QR Code typically used for?

A QR Code (Quick Response Code) is primarily utilized to embed various types of data, most commonly URLs. This functionality allows users to scan the QR Code with their mobile devices, which can instantly redirect them to a specific webpage, retrieve product information, or access multimedia content. The versatility in data encoding is one of the key attributes of QR Codes, enabling them to link to websites, videos, contact information, and more, all of which facilitate a seamless experience for users in accessing information quickly and conveniently.

In contrast, while there are tools and practices for storing employee information or organizing digital files, these functions are not the primary purpose of QR Codes. Similarly, although tracking web traffic is a valuable component of online marketing, QR Codes themselves do not perform tracking; instead, they serve as a means of directing users to a point where tracking can then be monitored separately through analytics. Thus, choice C accurately represents the true essence and primary function of QR Codes.
