  • Long-range electronic identification system
    Patent number: 10757915
    Abstract: An identification system is provided employing tags which may be targeted by a coherent energy beam such as a laser emanating from a query device controlled by a user. The tags may be activated with great precision even when tightly grouped and at great distances from the user through the employment of the communicated beam to activate the tags to report an identifier and or data stored thereon. The tags may be enable to rebroadcast a signal intended for another tag or form another tag in response to a receiver. The emanating laser is also adjustable for cross sectional contact area to increase accuracy. Security may be provided through the requirement of a proper query code being communicated to the tag prior to generation of a wireless data or identifier response.
