Performance Specifications
Dependent upon operating conditions and demands expected. If
used in a normal office environment with good read conditions,
you could expect to read up to six tags per second. Tags located
too far away or in poor locations with respect to interfering
objects provides poor results. The Reader gets very warm
during continued use. In high ambient temperature (or high
temperature within host computer) conditions, the reader could
overheat.
