Leveraging multiple APIs (Facebook, Twitter, Linkedin), we created Introduck, a mobile app that allows users to login via Facebook and input their various social networking credentials one-time.
This allows the personal information to be pulled without having them to type all their address and phone details manually. Once the user does this, he can exchange his contact details with multiple users within a radius of 10 metres via Bluetooth technology. All user information is also stored online securely, so that whenever there is a change in user contact information, it will be updated on other apps who had stored that user's information previously.
