ZDCARD invents a new metal UHF RFID tag that can serve as both a visual and digital tag for heavy and challenging equipment, vehicles and other assets and inventory typically found in challenging environments. The tag is made of anodized aluminum, can be mounted on metal and can transmit a signal in response to interrogations at a distance of 2 to 7 meter. 

The tag, known as the Metal RFID Tag, can be attached to equipment at oil and gas drill sites, to vehicles in outdoor lots, or to returnable metal containers. Before this, companies have often found such environments out of reach for RFID technology use, because tags would not survive for 

The duration of a tracked item’s lifespan.
