Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 2, the tamper-resistant flexible anti-metal electronic tag provided in this embodiment includes a tag main body 100, a trapezoid recess groove 101 with a recess is formed in the front side central position and the rear side central position of the tag main body 100, the top and the bottom of the trapezoid recess groove 101 are both open, two symmetrically disposed knife-shaped perforations 102 are reserved at the top of the tag main body 100, the tag main body 100 includes a U-folded paper-based antenna 1, the U-shaped opening of the paper-based antenna 1 faces left, a metal absorption layer 2 formed by a fragile material is adhered to the top, the inner side bottom and the bottom of the paper-based antenna 1, a metal absorption layer 2 is adhered to the top, the inner side bottom and the bottom of the paper-based antenna 1, the metal absorption layer 2 can absorb electromagnetic waves reflected by the metal surface, thereby realizing the purpose of anti-metal reflection interference, a 3 formed by a metal absorption layer 2 is adhered to the top, two middle surface materials 2 are adhered to each other, a waterproof cotton-mounted layer 6 is adhered to the top surface material 2, a metal absorption layer 6 is adhered to the bottom surface material 2, and the same as a metal absorption layer is electrically connected to the bottom of the RFID chip 2, the RFID chip is electrically connected to the bottom 2 by the metal absorption layer 2, the bottom is electrically connected to the bottom surface material layer 2, and the RFID chip is electrically connected to the bottom layer 2 by the metal absorption layer 2, and the RFID chip is electrically connected to the bottom layer 2 by the bottom layer, and the metal absorption layer is electrically connected to the bottom layer 2 by the bottom layer 2, when the tag body 100 is illegally peeled or illegally transferred after being peeled, the metal absorption layer 2 is broken, so that the RFID chip 4 and the paper-based antenna 1 are disconnected, the whole electronic tag can not be used any more, and the phenomenon that the electronic tag is illegally peeled or transferred is prevented.
