3D glasses having an RFID tag (embedded in one or more temples) are rented to theater or other venue operators. The glasses are shipped to a venue for distribution to patrons and collected from patrons in the trays. Inventory and other measures are implemented by RFID scanning while the glasses are in the trays (e.g., upon delivery to a theater, on collection from the theater, upon inspection at the 3D rental company, etc). Data gathered from RFID scanning and inspections allows the rental company to properly allocate rental costs to various venues based on shrinkage which includes, for example, extraordinary wear of the glasses, breakage or theft, which is attributable and traceable to the specific venues. The theater or venue may also independently scan the trays upon delivery and pick-up to maintain their own records. The invention includes 3D glasses with RFID, a washing rack, and rental systems.
