History of QR CodeFirst designed in 1994
A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently; extensions may also be used.

Pros and ConsRaising costs of printing
Thus, many efforts were made to improve the barcode technology and how much information they could store. What was done? The amount of digits in the codes were increased, layout was modified to include multiple codes, etc. However, these modifications came with drawbacks as well. The size of the barcode and printing space it needed increased, thus raising costs of printing. Also, with the developments came some occasional complications while attempting to read/scan the new codes.

AchievementImprove storage capacity and functionality
In response to the increasing demands for storage capacity, functionality, accuracy, etc. in addition to the negative factors associated with the developments in bar code technology, came 2D (two-dimensional) QR codes. And as with the development of barcodes, since their creation QR codes have seen increasing population, developments in the technology to improve storage capacity and functionality, etc.

Usage?First in the manufacturing process of vehicles
QR codes have come a long way since their creation, having first been developed to help track parts in the manufacturing process of vehicles. Today they have a number of purposes, including transport ticketing, entertainment, commercial tracking, and product labeling/marketing, just to name a few. You can find QR codes being used to send audiences to a website for browsing, to bookmark a webpage, to initiate phone calls, send short messages, send emails, produce links to web URL’s, start chats with blackberry users, connect to WI-FI networks, access information, get coupons, view videos, purchase items, process orders, advertise products, etc.

FutureGrow in popularity and use
So, what is the future of QR codes? Only time will tell I suppose, but judging on what we have seen so far with the technology, it looks like they will continue to grow in popularity and use. However not all seem to think so. How about you? Will you be using them now that you know more about them? Or how about even contributing further, you could even make your own. After all, there are plenty of free QR code creation/generator sites out there.

Securitybe aware and precautious of those
Okay, so I know after everything you may have read so far you may be excited to go out and start using QR codes, and that is great! But I wouldn’t be a good educator here if I didn’t warn you about the potential risks associated with their use. Like other technology, it is possible to be corrupted. And although I like to believe the majority of people out there are inherently good and pure hearted, you still have to be aware and precautious of those that will try to take advantage or do you harm.

MarketingA huge potential for easily sharing information
Of all its uses and functionality, QR codes have been utilized extraordinarily in the world of marketing. Just think of how often you see them nowadays in your magazines, on the television, at the market, on the menu at the restaurant, etc. It is my belief that this trend is only going to increase, and why not? It brings such a convenience to the industry, a huge potential for easily sharing information between marketer and consumer, and in a user-friendly fashion. In fact a QR code can encompass every part of the transaction, from sales pitch to purchases

ChinaQR Code, why it works so well in China?
That’s quite surprising (to me). Coming from a country that QR code is literally everywhere, I used to scanning computer screens, posters in subway, restaurant tables, and goods in supermarket. The simple scan brings large convenience — making payment, joining social network, getting discounts, attaining information, and so forth.

AuthenticationWhy you shouldn’t scan two-factor authentication QR codes!
Here is a deal, most services that allow 2FA also include completely unnecessary data in their QR codes like domain name and your email address. But in order to log into your account, all you need is any TOTP-generator app and an appropriate secret key. That’s all. So all additional data becomes a security vulnerability that can be exploited.
