Disadvantages of QR Codes

QR in QR codes[1403] stand for Quick Response. It is a two-dimensional code which consists of black modules that are shaped like a square on a white background. QR code is different from a bar code, although they have been compared numerous times. As the name suggests, bar codes are in the form of bar or lines grouped together.

QR code is used to encode with data such as numerical (binary, hexadecimal) or alphabetical and various other encoding languages. It was first used for the automotive industry but it is now applied into various other industries because it is capable of storing data in large amounts and is also easy to read.

Origin of QR Codes

QR codes were designed by a subsidiary of Toyota, Denso Wave, to whom the QR code trademark is registered under. It was designed to track vehicles during manufacturing the process. It can be decoded at lightning-fast speed which makes it highly efficient and helps increase work flow.

The use of QR code has developed a lot so you can now customize your very own QR code with different colors and other format. It doesn't have to be black modules anymore. It can be green, blue or red and so on.

Depending on what data you choose to store a QR code (numbers, alphanumeric, and kanji which is a Japanese language) with, the amount of data which can be stored varies. Kanji has the lowest storage capacity at a maximum of 1,817 characters only while decimal number has the highest storage capacity at a maximum of 7,089 characters.

With adverts printed on magazines and billboards etc., you cannot easily make changes. When you want to change the product you are advertising, you will need to print a replacement, which will cost you more money and take up most of your time. With QR codes, you don't have to reprint anything. All you have to do is change the redirected link to a new one. Thus, you can use the same QR code to advertise different products without additional costs.

QR code can be printed anywhere and on any type of materials, whether its paper or plastic or anything. So the possibilities of mobile marketing with the use of QR codes are limitless. Their form factor is small and compact so they won't take up much space, but they can act as a gateway to a website or data with countless information.

QR code is a registered ISO standard so it is free of any license and thus can be used by anyone without having to worry about copyright or intellectual theft issues.

Microsoft too has come up with its own version of QR codes named MS tags. QR codes can be read by a reader or a mobile phone with a camera but an MS tag can only be read by a Microsoft Tag Reader.

Bar Codes versus QR codes

You have probably heard about bar codes and bar code readers and how an app in your mobile lets you read bar codes. Well, it's going to do the same with QR codes but instead of displaying information about the product, it will do much more.

It will work in the same manner as a bar code reader app does. It will take the information from a product or an item - it can be a magazine, clothing, or an advert – and decipher the data right after. It’s similar to how QR code holds information about a company. Here, a business can store basic details about the company itself, its business locations around the country and the world, its new products, etc.

Advantage of QR codes over bar codes

The advantage of QR code over bar code is its large storage capacity. A QR code can store a higher volume of data compared to a bar code. But a QR code won't need a bar code for scanning the content.
