All tags require more power, sometimes twice as much, to write data than to
read it. This reduces the tag’s write range. If you have configured the IZ using a
maximum read range, you will not be able to write to the tags at this distance.
You must design the IZ for writing to the tag differently than your design for
reading the tags. Interrogators also require more time to write data to a tag than
to read data froma tag.An interrogator may be able to read 1000 tags per second
but may write only 10 tags per second
