Drones scope suspect flights

Drones could someday have a sort of invisible license plate that allows local authorities to determine who the unmanned aerial system (UAS) belongs too. Pitched by Chinese drone manufacturer DJI, the concept for an electronic identification system for small drones is just one of many ideas as the Federal Aviation Administration looks into potential ways of identifying drone users. DJI suggests drones should use the radio equipment already on board most systems to transmit a unique registration number. That number would identify the drone owner to law enforcement in the event of a complaint or flight through a restricted area. Areas with restricted drone flight, such as airports, could use radio equipment to read that number and report the ID number to the authorities.
