What is QR code? 2024

About QR Code

If you’re not familiar with Quick Response Codes (QR-codes), you’ve probably noticed that they pop up everywhere—online, in newspapers and magazines, on store windows, and in weird, pixelated black-and-white squares and even on t-shirts. Here we will take a look at what these codes are, how they work and how they are used.

What is QR code?

A QR code is very similar to a barcode, but because it carries data in two dimensions (horizontal and vertical), it can hold much more information than a one-dimensional barcode.

What is QR code?

In fact, a QR-code can contain thousands of data, compared to a barcode’s 20 alphanumeric character limitations. As a result, a QR-code can be used to share multimedia content, a landing page, or an entire ebook. However, QR-codes can do more than that – they can direct a phone to perform specific actions. For example, a theater company might provide a QR code that adds not only the person who scans it for showtimes and ticket information but also information about the dates, times, and locations of upcoming shows to the phone’s calendar.

QR-code is unlimited. Unlimited information, messages, videos, and content can be transferred in limited areas with QR-codes. You can access all kinds of details about the product, from the promotional video of the product to the user manual, in a magazine advertisement, on a billboard, in the store, or on TV, just by scanning it. QR-Code arouses curiosity. One wonders what is in that QR-code, by the natural human structure. It becomes an indispensable element for guerrilla-style advertising campaigns. With the proper editing, it is possible to increase the level of curiosity and increase the feedback.

History of QR-codes

QR codes were designed by DENSO WAVE in Japan and first used in 1994. Although “QR-code” is a registered trademark, the technology itself is not patented and is therefore available to everyone. An essential benefit of these codes for Japanese is that they are one of the most efficient ways to encode Japanese characters. In addition, its high data capacities, small output sizes, and resistance to dirt and damage (QR-codes can still be read when 30 percent of the code is corrupted) have allowed this technology to expand into other applications. Also, unlike barcodes that can only be read by a dedicated scanner, many smartphones can scan QR-codes, making them an excellent way to provide a large amount of information in a tiny space.
