What advantage does a 2D/QR code offer over traditional barcodes?

1. It stores data in a single dimension

2. It is less expensive to produce

3. It stores data horizontally and vertically

4. It can only be scanned from short distances

The correct answer is: It stores data horizontally and vertically

The advantage of a 2D/QR code lies in its ability to store data both horizontally and vertically, which significantly increases the amount of information that can be encoded within a single code. Traditional barcodes are one-dimensional and can only hold a limited amount of data, as they encode information in a linear format. This limitation means that more complex data, such as URLs, contact details, or even images, cannot be efficiently stored in a traditional barcode. In contrast, 2D codes like QR codes utilize a matrix format, allowing them to encode a much larger volume of information. This characteristic not only enhances data capacity but also contributes to improved scanning efficiency, as QR codes can be scanned from various angles, and they can still be interpreted by scanners even if damaged or partially obscured. The other options do not reflect the true strengths of 2D/QR codes. For example, while they may be more cost-effective depending on production variables, cost is not inherently a defining advantage over traditional barcodes. Furthermore, 2D codes do not have a restriction on scanning distance and actually allow for scanning from a distance of several meters if the code is large enough. Lastly, the nature of data storage in 2D codes contradicts the notion
