With the implement that stores information in a matrix with a set of points, can set as a two-dimensional barcode. This works as follows, there are special QR code readers that end up deciphering the information contained in the code, this is achieved through a mobile device.
The link between the QR code and WhatsApp
Adapting to current modernity and the development of new technologies WhatsApp has managed to scale in the use of new tools that are wonderfully coupled to current smartphones, how it was being produced in physical stores or products, including power lines, have implemented the use of QR code to facilitate the arrival of information to a user through their mobile, achieving this that it can have information such as locations, contacts or page links through a digital code.
WhatsApp has applied this to its new interface to save the user, having to ask for the number or share it, simply scanning the code WhatsApp makes a contact automatically add to your contact list, This use of the code also extends to other WhatsApp functions such as WhatsApp Web when used in the browser., where it is also accessed through a QR Code.
