Touch a Phone, Touch a Friend: Using RFID and Visual Tags With JSR 257 Contact
TS-3789

This session provides an introduction to the JSR 257 Contactless Communication API and to applications that can be developed with it. With the Contactless Communication API, Java Platform, Micro Edition (Java ME) application developers can write applications that enable users to share data, such as images and business cards, with a friend just by touching the other mobile phone. Near Field Communication (NFC) is used as the bearer to exchange data. JSR 257 also allows the development of applications that can read a URL on an RFID tag at the corner of a movie poster or write a phone number to a RFID tag on a business card. Application developers can also take advantage of JSR 257 when generating multiplayer games. In this context, the launch and possible Bluetooth pairing of the application on the other player's device can be done with the Contactless Communication API. Reading a visual tag (bar code) containing, for example, the URL of the magazine's web page, attached to an advertisement, is also possible with JSR 257. The Contactless Communication API also makes generation of visual tag images possible.

The use of RF identification technology is growing rapidly, and it brings new opportunities for application developers. Visual tags are already widely used in printed material. This session provides code examples and demonstrates how the JSR 257 Contactless Communication API can be used. No prior knowledge about RF identification or visual tags is needed to follow the presentation, because it covers the basics of these technologies.
