4) QR code reader

Answer 1

QR codes are the graphics that link mobile devices to various digital contents, and they are scanned using QR code readers.

Step-by-step explanation:

The graphics typically appearing as black and white boxes that automatically link mobile devices to a variety of content are called QR codes. QR stands for 'Quick Response', and these codes can be scanned using a QR code reader on smartphones or tablets. They have become a ubiquitous tool in connecting offline materials to online resources, whether that's to view text, play games, watch videos, or visit websites. As opposed to the other options provided like ISBN numbers which are unique identifiers for books, or barcodes which typically represent product information in a store, QR codes are designed to be a gateway to digital content. They're frequently used by graphic designers to add an interactive element to their designs, making them a modern symbol in corporate branding represented through logos.
