WebSphere brand IBM WebSphere Sensor Events, Version 6.2

Writing tag IDs

This section describes how to use the Asset Inventory Management Services for WebSphere® Sensor Events client handheld application to write a tag ID to an existing RFID tag. You should take caution when performing this task because it is possible to write the new tag ID to multiple tags instead of just one.

Before you begin

Print out a set of barcode labels using Asset Inventory Management Services for WebSphere Sensor Events that will be attached to each RFID tag.

You can use any barcode symbology you would like, as long as it meets the following criteria:

Furthermore, the output of the barcode reader must be the unencoded data representing the EPC in hexadecimal. For example, any symbology with the following construction, where data represents the hexadecimal value of the EPC, should be acceptable:

start code
data
checksum
stop code

The Code-128 symbology should be acceptable for most cases.

Go through each barcode label, attach it to an RFID tag, and then write the value of the barcode to the RFID tag using the following procedure.

Procedure
  1. Select Program Tag from the main menu.
  2. Read the barcode with the handheld device. The system checks to make sure that the value of the read is of an allowed length for an EPC code.

    If the value is not a valid length, you cannot write the tag ID.

  3. Pull the trigger on the handheld device to program the RFID tag with the tag ID, or you can click Restart to start over.
