There are many good ways to exchange your details with other like Microsoft’s tag and QR Code which we have talked about before but Bu.mp takes exchanging information to another level. This application allows you to exchange preconfigured data like Email, Phone Number, Photo, Address or the entire contact card by just bumping the phone together.
The application works on iPhone and Android and also has an API which can be used by other applications. Download your copy of Bump from here. Via TechSpikes
