A projectile is provided having contained therein a passive electromagnetically responsive device such as a tuned inductive-capacitive circuit. The circuit is preferably detected by stimulating oscillations at the resonant frequency of the circuit by a pulsed electromagnetic field. The projectiles are desirably used to enable remote tagging and detection and/or identification of objects including livestock.

A projectile adapted to be shot toward and to threby be implanted into livestock such as cattle for thereafter enabling remote electromagnetic detection and identification of said livestock when they are in an interrogation zone, said projectile comprising a plastic body having outer dimensions including an external diameter of not greater than 0.3 inches (7.5 mm) and a length of not greater than 0.75 inches (19 mm), thereby enabling the non-lethal penetration of the projectile a short distance into said livestock and a passive electromagnetically responsive device sealed therewithin capable of providing an electromagnetic response to an external electromagnetic field to enable remote detection of said projectile.
