We expect that most cellular phones and notebook computers will have Bluetooth in the near future. Many convenient applications will flourish. An example is exchanging multi-media electronic name cards using cellular phones. Today, most people carry a cellular phone. If the user interface can be made as simple as handing out a printed business card, the electronic cards exchanged over Bluetooth would make printed ones obsolete. However the current Bluetooth specification is not adquate to support short peer-to-peer transactions requiring symmectric user interface and fast response time. Connection establishment can take more than 10 s and two devices must start in an asymmetric manner. In this paper, we propose a random inquiry procedure tailored for name card exchange. It allows a symmectric user interface, and device discovery completes within 280 ms with probability 0.999. With this performance, it then becomes practical to provide a hot button on cellular phones that users will simply press to exchange electronic name cards.
