Electronic tag

Abstract

The invention discloses an electronic tag, comprising a substrate, an antenna, a chip and a plurality of connection lines; wherein the substrate comprises a first part and a second part; the antenna and the chip are arranged on the first part of the substrate; a plurality of pins of the chip are respectively connected with the plurality of connection lines; one end of each of the connection lines, which is not connected with the chip, is connected to a grounding terminal or a power supply, or is connected with the plurality of connection lines in short-current manner to extend to the second part of the substrate. When the electronic tag is unpacked to subject to data reading operation by a reader, the quantity of the pins detected to change connection condition exceeds the preset threshold; and meanwhile, the stored data of the electronic tag are deleted, the electronic tag cancels permanently to respond to the reader, the security of the electronic tag is improved, and the application and arranging cost is reduced. Additionally, the electronic tag is simple in structure and is convenient to install, protected commodities do not need to have special structures, therefore, the electronic tag is used widely.

Description

technical field [0001] The invention belongs to the technical field of commodity identification and anti-counterfeiting, and in particular relates to an electronic label. Background technique [0002] Commodity identification marks are widely used in modern property management, commodity retailing and other fields. The traditional commodity identification mark is to print a barcode representing commodity information on the commodity packaging, and manually bring the commodity close to the photoelectric scanner for scanning and identification. Commodity identification based on barcodes has major defects, such as barcodes contain little information, can only identify one type of commodity, and the recognition distance is short, so they must be scanned and identified one by one. [0003] At present, electronic tags have been widely used as emerging commodity identification marks. The core technology of electronic tags is radio frequency identification (Radio Frequency Identif...

Problems solved by technology

However, there are defects in this method: only destroying the antenna of the electronic tag can only temporarily invalidate the electronic tag as a whole. Data, the electronic tag can be repaired by adding a new antenna

[0006] However, in the technical solution disclosed in the above-mentioned patent document, the chip must be destroyed by means of an additional mechanical device. Small
