But what is a QR code?
Yes, we can get the most out of the camera on our mobile phone. More than anything because any mid-range mobile offers a photographic section that has nothing to envy professional models, as long as there are adequate light conditions. To this, add the large number of apps to edit videos on Android. And now, you can even scan QR codes.
It is true that QR codes have been with us for a long time. In addition, surely you have seen them on more than one occasion. That set of strange hieroglyphs without any meaning and that are made up of hundreds of points inside. But what are QR codes really? And what are they for?
Well, say that QR codes, or quick response (Quick Response in English), saw the light long before what you think. It was in 1994 when the Japanese company Denso Wave created this evolution of the traditional barcodes. We are talking about a module that allows store information and transmit it high speed, being represented in a matrix of points which are accompanied by three large squares at the ends.
The first sector in which they were used was in the automotive industry. Yes, in the vehicle manufacturing area it was used to carry out part inventories. You only had to scan the QR codes to have the corresponding information. Later on, the administrative areas of all kinds of sectors were transferred, up to telephony.
More than anything because, through the QR code readers for mobile phones, began to get even more out of this format. Yes, we can take advantage of these little stickers much more than you imagine. For example, one of the most common uses for users is to insert web links in QR codes.
Exactly, instead of giving a really long and difficult web link to write, all you have to do is scan the QR code and you can automatically access the address. Ideal to offer additional information to the user, or offer the possibility of downloading files. On the other hand, say that mobile applications like Snapchat, Line or Twitter use QR codes so that users can share their profile much more comfortable

Therefore, it is very important not to scan any QR code, especially those that are suspiciously on the street. Obviously, the invoice for the services you have contracted may have a code of this type and it is not malicious. Or in a store that invites you to connect to its WiFi network through this same tool. The only thing you have to have is a little head.
