WonderCard

WonderCard is a business card app used to swap contact info using smartphones.

WonderCard app generates a virtual business card that is stored on the smartphone and enables seamless contact exchange of contact information with 100% accuracy. If desired, the virtual business card can be printed on a card like a traditional business card and the app would work just as well when reading from it.

The best part of this app is that at some time later, if the person you met and used the app to exchange contact information relocates to a different address and updates his contact information, you will get that person's contact information updated in your address book automatically. And your contacts will never be out of date.
