Zusammenfassung:A method and system for preventing simultaneous deactivation of multiple electronic article surveillance ("EAS") tags. An RF pulse is transmitted within an EAS interrogation zone to induce a response from at least one EAS tag placed within the interrogation zone. The response of the at least one EAS tag is received. A presence of more than one EAS tag is determined by evaluating a frequency response curve corresponding to the response.
