Abstract
An identification device for removable mounting on a hooked member. The identification device includes a small cylindrically shaped member dimensioned to receive a free end of a hooked member. A cloth patch is adhered to an outside surface of the cylinder. The patch includes optically coded laser threads. When the threads are exposed to light, the threads lase, and emit identification signals (signal codes). Each thread's signal code may provide, for example, a unique identification number.
