The FTT Reader System has at least one of each of the following:
•
An FTT Reader that can connect to several external devices and
to other FTT Readers.
•
A computer to drive the system. The computer collects data from
the tags. The computer may also send commands via the
Readers to other devices that control doors, send alarms, turn on
lights, etc.
