The QR code is something every passing day more is established in our lives, as we find in a lot of situations and with different objectives. But do you really know what they are or how they work? We are going to explain it to you right now.
Nowadays you can find QR codes in a moment of different situations, from advertising, to the elevator of your apartment or at the bar of the bar where you go to have coffee every day, since it is being standardized at forced marches in our society. QR codes are used to share WiFi password easily in mobile devices.
QR code – what exactly are we talking about?
The QR code (Quick Response code) is an evolution of the barcode that is still used in many products. It is a module where information is stored in a two-dimensional barcode or a dot matrix. This type of information can be read from our mobile device as long as we have a reader ready for it.
As soon as we read a QR code, the application takes us to the Internet to interpret everything that the code informs us that can be moved from a website, a map, an access to a social network or an email, among many other possibilities.
This type of system was created in 1994 by the Japanese company Denso Wave (owned by Toyota), although the patent of the barcode technology on which it is based as we’ve already told dates back to 1952 when Joseph Woodland him recorded in the shape of a target shooting target.
The Japanese standard for this type of code (JIS X 0510) was published in January 1998, while the international ISO standard version (ISO / IEC18004), the one we currently use for most QR codes, was approved in June 1998, year 2000.
How does it work
A QR code is a graphic pattern where information has been placed in the form of points and lines, both black and white so that an application specialized in this type of coding can read it and display the information it stores. QR codes can be of various types with a maximum of 177 x 177 elements and a size of up to half a DIN A4 page.
They consist of two elements such as:
- The three squares at the corners, which are the ones that guide the mobile reader’s scanner.
- The rest of the code, which is where the information to be transmitted is integrated.
What utilities do they have?
As we have already mentioned, QR codes are used to store information, so this concept is so broad that it could be anything. Anyway, there are certain topics that are the most used in relation to this type of systems:
- URL address : the most common is that a QR code opens a specific web page with the information that you want to show.
