What is QR Code?

QR Code Overview

Basically, a quick response (QR) code is a two-dimensional barcode, and it contains encrypted data such as URL or personal details. It consists of black modules arranged in a square pattern on a white background. The three big identical squares on the top left and right corners as well as the bottom left corner are called the position detection patterns. The QR code also has one or more smaller squares, called the alignment patterns. The black irregular patterns in the QR code contain the encrypted data. So when your phone’s QR code reader software scans this image, they will interpret the information from those tiny patterns.

QR Code Advantages

This code was developed and commonly used in Japan, but recently it has started to be used in other countries as well. The use of the code is becoming more and more popular due to the many advantages it has to offer.

Many small and big businesses use QR codes as a marketing tool. It is cost effective and is relatively easy to use. Businesses often use it to encrypt information about their company such as product reviews from client, corporate vision and business mission statement, or even details on their upcoming promotional events. They can easily encode this information into a code and distribute it to their clients/customers.

Thanks to this technology, companies can save a lot of money, especially on production of promotional brochures. It is not uncommon to see a big billboard with a QR code at the corner at the corner of the board. Passersby can scan the barcode using their mobile phone camera and retrieve additional information that the billboard might not have.

Printing out tons of brochures or catalogues can be very costly and time consuming, not to mention that people would end up throwing them away anyway. Websites are usually seen as an alternative to these, many companies or even public figures would write about the details of their business or upcoming events on their websites. However, people would have to remember the URL and very often has to rummage through the website to find a specific information.

Now, business owners or public figures can promote their websites or share specific information using QR codes.

For example, a restaurant owner can put a code image on the advertisement poster of his restaurant. Once scanned, potential customers will be able to retrieve information about the restaurant such as the menu served, its location, or even contact details.
