Note
Note that in a metallic environment the values for the limit distance are reduced.
Operation in dynamic mode
When working in dynamic mode, the transponder moves past the reader. The transponder
can be used as soon as the intersection (SP) of the transponder enters the circle of the
transmission window. In dynamic mode, the operating distance (S

Dwell time of the transponder

The dwell time is the time in which the transponder remains within the transmission window
of a reader. The reader can exchange data with the transponder during this time.
The dwell time is calculated thus:
