Nice Sensortags.

The Sensormatic supertag II is the greatest of all sensortags. Other technologies have come and gone, but the Supertag has been on top for a long time and shows no sign of relinquishing its position. Why is the supertag so good? It has a patented locking mechanism that is not defeated by a magnet. The supertag pin is extremely difficult to cut off illegally. Most metal products will not affect the supertags functionality. Best of all, the supertag hand detacher is manufactured with built in security measures to prevent shoplifting.
