I would like to know that if like "tel:", "mailto:", "sms:", etc.. is there a URI Scheme to prompt the user to save a contact to his smartphone.
For example, the user is browsing on a web page and clicks a button, he is then prompted to save a contact on his phone.
I know there is vCard, but the user has to download it then open it, unlike "tel:" or "mailto:", is there an equivalent of those for saving a contact?
