What does QR stand for in QR code and how does it work? 

Before we jump into the basic works of a QR code, we must first learn the basic concepts of a QR code.

A ‘Quick Response Code’ also known as QR code is a two-dimensional type of barcode that Denso Wave develops, a Japanese barcode developer, in 1994.

Today, QR codes are generally used in advertising, business, health care, and education. 

However, business sectors, especially in the advertising and operations, most widely use QR codes. Aside from these sectors, the restaurant industry also employs an interactive restaurant menu QR code software and QR code generators to generate menu QR code for their business.

You can find QR codes in brochures, flyers, posters, billboards, items and products, business cards, and even online websites such as social media and shopping sites.

There are two types of QR codes: the static QR code and Dynamic QR code.

Brief History of QR codes

The use of technology alleviates people’s efforts in labor. Just like the creation of QR codes, it holds a specific job to alleviate. In the early 1960s, the economy of Japan entered high economic growth.

During this period, supermarkets and convenience stores thrive and are selling a wide range of commodities ranging from food to clothing. 

To keep up with the demand for checkout counters, the use of cash registers was implemented. Due to manual inputting in checkout and sales, cashiers on the checkout counters experience numbness on their wrists and developed carpal tunnel syndrome.

As a solution to the problem, the Point on sales (POS) system was developed and incorporated the use of barcodes. 

In the long run, developers noticed the problem barcodes hold. The limit of 20 alphanumeric characters was not enough in holding a product’s information and the position of how a barcode is scanned leads to scan failures. 

Denso Wave stepped in and devised a new type of barcode that could hold more information and can be scanned in any scanner orientation.

Thus, the rise of QR codes promulgated in 1994 and has made history up to today.
