Method for tagging articles used in conjunction with an electronic article surveillance system, and tags or labels useful in connection therewith
First Claim
1. A method for providing a facility with articles to which devices have been attached which are capable of being detected by article surveillance equipment located at said facility, said method comprising:
- attaching to said articles, before they reach said facility, devices which are not capable of being detected by said equipment, but which are capable of being activated to become capable of being so detected;
supplying said articles to said facility; and
activating said devices upon receipt at said facility.

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

17. A device for interacting with an electronic article surveillance system, said device including a resonant circuit for interacting with an applied radio-frequency field produced by said electronic article surveillance system;
-
wherein said resonant circuit is configured to resonate at a first frequency corresponding to an operative frequency of said electronic article surveillance system in a first mode of operation; wherein in a second mode of operation said resonant circuit is configured to resonate at a second frequency different from the operative frequency of said electronic article surveillance system, and is capable of activation for interacting with said electronic article surveillance system; and wherein said resonant circuit includes means for modification from said second mode of operation to said first mode of operation, which is operative at said second frequency. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
