I'm currently building a site where, with one touch, you should be able to add a contact to your IPhone/Android Address book. The website is currently HTML5, but Javascript and/or PhP options could be implemented.
So is there a way that on the click of a link, the mobile device will open the Adress book already filled with the info I want it to have (Name, EMail Address, Street Address, Phone number).
I've looked everywhere to only find ways to program apps that would do the same thing. I want to make it from a webpage. Anywhere I can learn how to do this?
PS: Currently, I'm trying with everything in a .VCF file that could be downloaded on the click... this seems to lead me nowhere at the moment.
