📷 What is a QR Code?
A QR code is a two-dimensional barcode that consists of black squares arranged on a white background. It can store various types of data, such as URLs, contact information, Wi-Fi network details, and much more. QR codes were first invented in Japan in 1994 by Denso Wave, a subsidiary of Toyota, to track vehicle components during manufacturing. Since then, they have gained popularity worldwide and are commonly used in marketing, advertising, payment systems, and information sharing.

✅ Time-saving: Scanning a QR code eliminates the need to manually enter lengthy URLs or search for information online. It streamlines processes and saves valuable time, making it an ideal tool for businesses and consumers alike.
✅ Enhanced engagement: For businesses, QR codes offer an interactive way to engage with customers. By providing exclusive offers, discounts, or valuable content through QR codes, companies can enhance customer experience and build brand loyalty.

Disadvantages of Scanning QR Codes
⛔ Requires a smartphone and an app: To scan QR codes, you need a smartphone with a built-in camera and a QR code scanning app. While most modern smartphones have this functionality, it may pose a limitation for users with older devices or those who prefer not to install additional apps.
⛔ Dependence on internet connectivity: Scanning QR codes often requires an internet connection to access the encoded information. If you’re in an area with poor network coverage or no access to the internet, scanning QR codes may not be possible.
⛔ Security risks: As with any technology, there are potential security risks associated with QR codes. Malicious codes can redirect users to phishing websites or download harmful software onto their devices. It is essential to exercise caution and only scan codes from trusted sources.
⛔ Limited user familiarity: While QR codes have gained popularity, some users may still be unfamiliar with how to scan them or may not understand their benefits. Educating users about QR codes and their applications is crucial for successful adoption.
⛔ Design limitations: QR codes are functional but not aesthetically pleasing. They are typically black and white and may not blend well with certain design elements. However, creative customization options, such as adding logos or colors, can mitigate this drawback.
⛔ Content restrictions: Due to their limited storage capacity, QR codes may not be suitable for storing large amounts of data. If you need to convey extensive information, alternative methods like URLs or NFC (Near Field Communication) tags might be more appropriate.
