Abstract
A security system including a security tag for attachment to an article sold in a retail establishment, the security tag being formed with a coil having a tuned resonant frequency. The coil is formed of a composition of materials that includes a flake-like conductive metal that is intermixed with a resin, solvent and additives to define a paste-like composition that is adhered to a substrate in a coil configuration. A neutralizer device is formed as part of the security system and is operated to produce a high intensity magnetic field that emits eddy currents for melting the coil and thereby disabling the security tag when the tag is placed in close proximity thereto.
