Abstract
Various embodiments of object tracking systems and related methods and devices are disclosed. One enclosure for object tracking comprises an interior space that is designed to contain radio frequency identification (RFID) tag. The enclosure further includes top, bottom and side walls that form the interior space. The walls are designed to prevent very little or no radio frequency (RF) signals leakage outside of the enclosure. The side walls include a front wall that includes at least one slot to facilitate accessing the interior space. The enclosure further includes at least one access member that is designed to move in and out of the enclosure via the at least one slot. The access member includes extending members that are designed to cover the openings between the access member and slot, thus preventing very little or no RF signals leakage outside of the enclosure.
