Reading Transponders
The IH21 UHF Reader can read and write to UHF RFID tran-
sponders when they are in range of the antenna. The antenna is
located on the front of the IH21 UHF Reader and the read zone
is in front of the antenna.
The range at which a transponder can be read depends on the
transponder type and size, and the number of transponders in
the field.
