Abstract (en)
[origin: WO9106934A1] Electronic article surveillance (EAS) tags (20) are attached to articles of merchandise, not at the store (16) using EAS equipment (18), but in conjunction with the manufacture (10) of these articles. At that stage, the tags (20) are not detectable by the EAS equipment (18). They are made detectable upon receipt by an EAS-using store (16). For swept frequency RF EAS equipment (18), the tags (20) are initially provided with two capacitors (24, 25) which make the tags (20) resonant at a first frequency not detectable by the store's EAS equipment (18). To activate them, one capacitor (24, 25) is disabled, thereby making the tags (20) resonant at a different frequency which is detectable.
