Abstract

The invention discloses an anti-theft electronic tag. The electronic tag comprises a power module, a radio frequency module, a tearing perceiving module, a main control module and a storing module, wherein the power module supplies power for the electronic tag, the tearing perceiving module is used for perceiving tearing state information of the electronic tag, the main control module receives the tearing state information sent by the tearing perceiving module and controls the radio frequency module to send tag identification information, the storing module stores the tag identification information to be sent when a reader is powered down, and the tearing perceiving module comprises a photosensitive detection unit or a broken line detection unit. The electronic tag can perceive and trigger the main control module to send corresponding tag identification information through the photosensitive detection unit or the broken line detection unit when the electronic tag is torn off, is far in reading distance, low in power consumption and long in service life of batteries per unit capacity.

Description

technical field [0001] The invention belongs to the field of radio frequency identification (RFID) electronic tags, and in particular relates to a low-power consumption RFID anti-theft electronic tag that can be sensed and give an alarm after it is installed on the surface of an article. Background technique [0002] RFID technology uses radio frequency signals as the carrier, through the reader to automatically identify the electronic tags pasted / installed on the item, so as to obtain the relevant data of the item, the identification and authentication process is carried out automatically, with non-contact, non-visual reading, With the advantages of fast reading speed and simultaneous reading of multiple electronic tags, it can be applied in various harsh environments such as oil, dust, and high temperature. [0003] RFID electronic tags made of wireless radio frequency chips are durable, have strong penetration in information reception and transmission, and have large stor...
