Example: Creating a UID reader

This example shows you how to create a simple Near Field Communication (NFC) MIDlet that reads data from contactless targets and displays the data on the screen. The data read is the unique identifier (UID) of the target, and it is read only from an NDEF target. UIDs are factory-programmed and can be used to distinguish between targets.

Note: The MIDlet does not read the actual NDEF message (payload) from the target.

Prerequisites

You need the following to develop and test this MIDlet:

Symbian^3 SDK 1.0 for Nokia devices or newer
NFC plug-in for the Symbian^3 SDK 1.0 for Nokia devices if you are using this SDK release
NFC-enabled Symbian device with Java Runtime 2.2 for Symbian or newer

For instructions on how to set up the Java ME development environment, see section Setting up the development environment.

Development
