The Multiple Antenna Reader System (MARS-1/-2/-4/-6) is an RFID reader-writer designed to operate up to 6 external antennas (MARS-6) and to meet the requirements to verify, inventory, monitor and control a large number of valuable items located in one position or moving on a conveyor at high speed.

The MARS is a high performance system for PJM StackTag® and PJM ItemTag® RFID tags. It provides fast and reliable operations with different external antenna types.

The MARS-1 operates with a single antenna. MARS-2, MARS-4 and MARS-6 operates with either a single antenna or multiple antennas (up to 2, 4 or 6 accordingly).
