What Is A QR Code? The Following Is An Explanation And History

YOGYAKARTA - When we are in a luxury restaurant, usually we will be faced with cash payments, or non-cash, either via E-Banking or QR codes. So do you know what QR codes are? Let's discuss here!

QR Code stands for Quick Response Code. The QR code does look simple, but it turns out that this black-and-white small box can store various kinds of information.

The use is classified as practical, you just need to direct a smartphone or another scanner machine to a QR code. Within seconds, the data you need is in your hands. QR codes can also facilitate transaction processes and data collection.

QR code is a 2-dimensional matrix technology that is able to put various types of information in it. Information that can be accommodated by a QR code reaches 7089 digits and 4296 alphanumeric characters.

Alphanumeric are letters, numbers, and special symbols (former reading marks and mathematical symbols). Therefore, the description of goods, telephone numbers, to the URL of a web can be accommodated in it.

QR code can accommodate a lot of information because it uses 2-dimensional technology that can code information across and out.

Unlike barcodes that use one-dimensional technology and can only encode information in the transverse direction. So that the barcode can only accommodate very little information, which is a maximum of 20 characters.

History Of QR Code

The QR Code was first introduced by DENSO WAVE to the public in 1994. The development of this technology was led by Masahiro Hara and Atsushi Tano. The development of the QR code technology began with the transformation of the production system in Denso Wave.

In the 1980s, barcodes were used in many industries, including manufacturing, distribution, and retail. Now in 1990, there was a fairly large change from a mass manufacturing of one type of product to a more flexible production system.

Therefore, a more detailed production control system is needed in the position of product manufacture. In this regard, a barcode is needed that can put more data.

In 1992, Masahiro Hara was asked by the manufacturing department to increase the barcode scanner that could work faster. Unfortunately at that time the barcode could only accommodate a maximum of 20 alphabet personalities.

Thus, workers are required to scan around 1000 barcodes per day to obtain the necessary information. Instead of accelerating the work process, this matter is even very troublesome and ineffective. In response to what happened in the field, Hara took the initiative to improve the new code system.

At that time Hara said, 'We will improve the compact code which can put more data, listed the character kanji and kana at the same time can be read at high speed.'

In the process, Masahiro Hara and Atsushi Tano took 1 year until the conclusion was to create a stable QR code, able to put around 7000 characters and can be scanned 10 times faster than other barcode types.

In 2002, the QR code was used in lausa in Japan and in 2004 it received standardization from JIS (Industrial Standard Rate).

Even so, QR code popularity has decreased in 2013 because many people in the world do not understand what QR code is and how the technique uses it. Only in 2014 the QR code began to gain popularity again, because smartphone ownership is increasingly universal.

In addition, you also need to know how to scan the QR Code from images on your Laptop.
