6.11 Tag Test
The tag test tool can be used to test the reliability of tags.
To access this tool, select Tools->System->Tag Test
This is of use to tag manufacturers only. All tags in the field will have already been through this process.
Each tag is sent 10 read commands and the number of replies is counted. If the tag passes a threshold,
then a write command is sent. There are also optional additional write commands to configure the tag's
behaviour. This tool is shown in Figure 35 and its controls described in Table 20.

Index Description
1
Shows tag messages as they are being tested. It is advisable to resize the window so that a complete test of a
single tag can be seen at once.
2
Turn off power between tests will keep reader power off, except when a tag is being tested. This is useful for
cases where the tag must be positioned before the test is performed. In this case, the Run Test button is
enabled. This must be clicked each time a test is to be run.
3
Fail double zero ID if ticked will reject tags with 00 for the lower byte of the specific ID. This was needed to
handle a batch of tags that accidentally included 2 tags with the same ID of 00 in every batch of 256 tags. This
is not needed for all tags other than those with this problem.
4
Write to group ID and conditional ID writes values to 2 common tag configuration areas. The values are in
hexadecimal.
5
Write to configuration word writes to the tag configuration. See 3.7 of Chip Logical Specification document
for details.
6 Lock to word sets the tags lock pointer.
7
Replies out of 10 to pass tag controls the pass/fail criteria. In most cases, the default 8/10 is a good value to
use.
8
The Number of successes field shows how many tags have been tested and passed successfully. This count can
be reset by the Reset Success Count button.
