Radio frequency identification technology has been widely used in the field of smart tag products.

In the current technology, the most common communication frequencies of smart tags include ultra high frequency (generally at 860-960MHz) and high frequency (13.56MHz), the high frequency smart tags are mainly used in application scenarios with short communication distance (such as clothing hangtag products), and the ultra high frequency smart tags are mainly used in application scenarios with long communication distance (such as transportation, warehousing, etc.). The intelligent label in the prior art can only select to adopt a high-frequency intelligent label with short communication distance or an ultrahigh-frequency intelligent label with long communication distance according to the scene applied as required, however, the intelligent label is found in practical application, along with the development of technologies such as storage logistics of various products and the like, people hope that the adopted intelligent label can realize short-distance communication, and can realize long-distance communication in logistics transportation and storage links, the use convenience is improved, the use cost of the intelligent label can be obviously reduced, but no intelligent label product capable of meeting the requirement exists in the prior art. Therefore, the prior patent application 201922045323.3 of the applicant discloses a dual-frequency intelligent label and a dual-frequency intelligent label tag thereof, wherein the high-frequency intelligent label is directly attached to a blank area, so that the dual-frequency intelligent label is obtained, short-distance reliable communication can be realized, long-distance sensitive communication in logistics transportation and storage links can be realized, the use convenience is improved, and the use cost of the intelligent label can be obviously reduced.

Specifically, the DR acousto-magnetic anti-theft label belongs to one of acousto-magnetic labels, the core structure of the DR acousto-magnetic anti-theft label is a DR amorphous wafer, and the DR amorphous wafer is molded after plastic package treatment, wherein DR is an abbreviation of Dual-Resonator and means a resonance piece. The DR acousto-magnetic anti-theft label belongs to an anti-theft label which can not be reused, can lose effect after demagnetization, and is mainly applied to small easily stolen goods in a shopping mall, such as clothes or various ornaments.
