Abstract: A security tag that can be attached to an item or items that provides a zero or low impact to the item or items such as elegant or soft goods. The security tag includes a security element that is enclosed within a pliable material that is coupled to the item or items it is protecting by either a lanyard or by passing a portion of the unfinished garment through aperture(s) in the pliable material. The lanyard can take on various compositions and can couple to the pliable material using different latching mechanisms. No puncturing, piercing or adhesive attachment to the elegant or soft goods occurs, thereby making a “zero or low impact” on the item while also making a pleasant presentation to customers when the item (or items) is displayed.

Abstract: A resonant tag for use with a radio-wave detection system for the prevention of shoplifting or the like, which has a coil and capacitor circuit formed on opposite sides of an extremely thin substrate of a biaxially-oriented polypropylene, with one of the capacitor plates formed on one side of the substrate and the coil and other capacitor plate formed on the other side of the substrate, and paper layers on both sides of the tag, whereby the circuit is destroyed when the tag is washed in water or dry cleaned.

Abstract: A resonant circuit for use with a radio-wave detection system for the prevention of shoplifting or the like which has a coil and capacitor circuit whereby the circuit is permanently destroyed when the tag is exposed to a radio signal that causes a voltage across the capacitor that exceeds the breakdown voltage of the capacitor. The capacitor comprises a dielectric that does not exhibit self-healing. Such dielectrics include ceramics, metal oxides and minerals.

Abstract: A microwave-resistant and waterproof security tag for use with food products, especially meat products. The security tag includes a pair of single, open loop conductive traces in between which is disposed a similarly-shaped dielectric layer. This combination is encapsulated within plastic membranes or covers that are sealed at their common edges. The preferred embodiment includes rectangularly-shaped single, open loop conductive traces with rounded corners and with one end of each trace forming a capacitor plate. The width of each trace is at least 1/10 of the length of the security tag.
