A PIT tag reader generates a magnetic field from a loop antenna to inductively charge a tag.  The tag returns an 80 bit message that contains a unique identification number.

Our ORSR single and ORMR multiple antenna readers are standalone monitoring systems that are designed for long term unattended operation.

Two types of technology are used for low frequency RFID, Half Duplex (HDX) and Full Duplex (FDX).  Some readers read one or the other type while dual mode readers detect both

Our HDX reader will operate from 6 to 24 VDC.  Increasing the voltage can sometimes increase the read range.  A higher supply voltage (18-20 volts) is needed on very large antennas (30 meters or wider).  Smaller antennas do not usually benefit from more than 12 volts.
