The Roswell, the first tag of its kind, uses only its aluminum exterior as an antenna. The patent-pending tag is constructed of two cylindrical metal cases with a thin high temperature substrate between them. While existing products in the market may use a tag packaged inside a metal case, Roswell is completely different. Because there is no RFID tag packaged inside Roswell, the antenna-free design ensures reliability and durability by eliminating the risk of tag failure from high impact and vibration. Roswell also eliminates the need for a spacer between the tag and the mounting surface or the need for strict welding or attachment procedures. There is absolutely no transmission loss associated with the way the tag is attached.
