Handshake is a virtual roller deck that allows you to keep track of all the contacts you’ve exchanged business cards with and lets you share your business card with new contacts. But Handshake goes even further by adding every contact to your phone contacts and LinkedIn connections (provided both options are turned on).
The app is very simple to use. Open the Handshake app and place your phone together with the person(s) you want to share with and click the handshake button, the app will use Bluetooth to share your business card with the people you wish, no muss no fuss.
