Problems solved by technology

[0006] The purpose of the present invention is to provide a dual-frequency electronic label with low frequency and high frequency, which solves the technical problem that the existing electronic label only has a relatively simple anti-counterfeiting identification function relying on its decoding circuit, and can only be applied to the 8.2MHz low frequency band The technical problem of the environment (decoding equipment), which not only has the ability to process more complex information, but also expands the storage capacity of information

Embodiment Construction

[0019] see Figure 1-2 , they are a dual-frequency electronic tag with low frequency and high frequency in the present invention. As shown in the figure: the base layer of the label is composed of an insulating film layer and a conductive layer attached to the insulating film layer. The conductive layer is composed of an 8.2MHz RF low-frequency tag line arranged in the middle and a 13.56MHz high-frequency RFID tag line arranged on the periphery of the low-frequency tag line; the low-frequency tag line consists of decoding points 4, 12, and a low-frequency coil 7 and capacitors 5, 13; the high-frequency label circuit is composed of high-frequency coil 6, high-frequency circuit connection points 1, 9, 2, 10, 3, 11 and a chip-binding circuit that binds an ultra-high-frequency chip 8 . The capacitor 5 in the low frequency label circuit is located in the low frequency coil. The insulating film layer is PET or PTN, and the thickness of the insulating film layer is 1-100 μm. The ...

Abstract

The invention relates to the technical field of security tags, in particular to a double-frequency tag with low frequency and high frequency. The base layer of the tag comprises an insulating film layer and a conducting layer attached to the insulating film layer. The invention is characterized in that the conducting layer comprises a 8.2MHz radio frequency (RF) tag circuit arranged in the middle and a 13.56MHz radio frequency identification (RFID) tag circuit arranged on the periphery of the low frequency tag circuit; the low frequency tag circuit comprises a decoding point, a low frequency coil and a capacitor; and the high frequency tag circuit comprises a high frequency coil, high-frequency circuit connection points and a chip binding circuit which binds ultrahigh frequency chips. The double-frequency tag solves the technical problem that the existing tags depend on own decoding circuits, only have simpler anti-counterfeit identification functions and are only suitable for the 8.2MHz low frequency environment (decoding equipment). The double-frequency tag not only has the capability of processing more complex information, but also increases the storage amount of the information.

Description

Technical field: [0001] The invention relates to the technical field of electronic safety labels, in particular to a dual-frequency electronic label with low frequency and high frequency. Background technique: [0002] With the development of electronic technology, electronic tags with security and anti-counterfeiting functions have gradually entered our lives. They also have the advantages of high sensitivity, small size, and low cost. [0003] For example, the Chinese invention patent specification (authorized announcement number: CN100423026C) discloses a high-precision radio frequency soft label. The base layer of the label is composed of an insulating film layer and conductive layers attached to the front and back of the insulating film layer respectively. The conductive layer has a decoding circuit composed of capacitors, wires and decoding points. The periphery of the coil is characterized in that: the width of the capacitor wire and the coil wire gradually decreases...
