Are you happy with your contacts in your phone? Do you have all necessary details? Did you have fun typing them in a letter by letter? Did it feel good giving someone a missed call to share/exchange your number? Did you ask them to pose for your contact picture? How many contacts have a picture by the way? Are you sure that you have the most up to date contact details of a person?
Contacts Card solves these problems by simply reversing the origin of contact generation. i.e. You generate your contact card, share it with others and control what information you share. Updating your card will reflect the changes in all your contact card holders, hence automating the process of latest contact details.
