Today I was thinking about how to simplify a rather familiar action: call the phone that is written on the site. And such an idea came to mind - why not make it so that when you hover the mouse cursor over a phone number, a pop-up hint with a QR code can be displayed, which you can immediately read using the phone and immediately call without rewriting the number manually.
Moreover, it is possible to record in such a QR code not only a number, but also various supporting information - such as an e-mail address, the name of a person, and so on - everything that allows you to record a vCard. Thus, the user can either call immediately or write the number to the address book in order to be able to call later. The contact will be immediately recorded in the address book with all the additional information that will be needed in order to find it later. ')
I think that such a pop-up hint with a QR code can be added in all basic cases: a user's phone in a social network (the name and so on can be taken from his own information for recording in vCard), a telephone for communication on the company's website (in the section “Contact with us ", either at the top or at the bottom of the page), phone numbers on reference sites (phone numbers of cafes, shops, other organizations) and so on.
The implementation of this will not take a lot of time (there are many ready-made libraries, for example, for Python there is pyqrnative and the pyqrcode QR code generator based on it), and this may well increase the usability of the site.
PS After the post was posted I wrote to me in the mail gorynych_zmey . It turns out that he is engaged in the implementation of this, so if there is a wish to join, then now you know who to contact.
