Final answer:
The black and white squares found in various types of media are called QR codes, which can be scanned with a smart device to access additional digital content like websites or videos. QR codes store more data than traditional barcodes by encoding information in both vertical and horizontal dimensions.
Step-by-step explanation:
The little black and white squares that you often see in magazines, posters, and store displays are known as QR codes (Quick Response Codes). A QR code is a two-dimensional barcode that can store information such as URLs, contact details, or texts. Unlike traditional barcodes that present data in the width and spacings of parallel lines, QR codes are read in two directions: top-bottom and right-left. This allows them to hold considerably more data.
When scanned with a smart device, these QR codes can direct the consumer to websites, videos, or images containing additional marketing information. This is particularly useful for businesses and events, as it provides an easy and interactive way for consumers to access more details. For instance, in a community event, a QR code may be used on a card for attendees to quickly access a website link, enhancing the event experience by offering additional resources or interactive elements, such as a word cloud projection.
Due to their storage capacity and convenience, QR codes have become an integral part of advertising, facilitating access to digital content in our visually saturated world. Retailers and marketers utilize these codes to bridge the gap between print media and digital content, thus creating a more engaging experience for users.
