The starting point of this template is this one provided by ShareLaTeX and originally made by Karol Koziol. Feel free to (re-)use, fork, modify and contribute to this project as long as you reference the original author(s) if you do so.

This template supports adding a QR Code that contains the MeCard format so adding a contact to your phone is very easy. The specifications for the MeCard format can be found here. Three examples are provided two of which have a QR Code. You can reuse these very easily if you replace the contact details with your own in within the command definitions.
I included three different examples in the pdf to show the potential of the template. Below I also included images of these examples:
Example with QR code instead of logo.
Original example with ShareLaTeX logo.
Example with QR code, twitter and different alignment.
