Electronic tag capable of being detected at long distance

Abstract

The invention belongs to the technical field of electronic tags, and particularly relates to an electronic tag capable of being detected at a long distance. A microchip and a directive antenna are arranged in the tag and the microchip is connected with the directive antenna. Paper packaging is adopted by the appearance of the tag. A breakage resistant line is arranged on the appearance of the tag. The surface of the tag is coated with an easy-to-stick adhesive. A fixed identification code is arranged in the microchip of the inner portion of the tag. The electronic tag capable of being detected at the long distance is high in sensitivity, strong in directivity, the unique identification code is fixed inside the electronic tag, the service life is long, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of electronic identification products, and in particular relates to an electronic label capable of remote detection. Background technique [0002] As early as 1700, Europe printed the first batch of labels used on medicines and cloth as commodity identification, so, strictly speaking: labels are used to mark the classification or content of your target, like giving your target Defined keywords, tools for yourself and others to find and locate your goals. [0003] Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, reading heads, communicators, and readers. The spatial coupling of the radio frequency signal is realized through the coupling element between the electronic tag and the reader; in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. Electronic tags are a...

Problems solved by technology

[0005] At present, everyone commonly uses some of the above-mentioned label detection methods, which need to be detected at a close distance. For example, when buying products in a supermarket, you need to take them out one by one and hand them to the scanner, and then put them back into the shopping cart one by one, such as In the parking lot, the car needs to be parked next to the card reader, and the car can only pass after the card is read. Sometimes the car is not parked in a proper position, which makes it inconvenient to read the card, and the driver has to get out of the car to read the card, which is very difficult. is trouble
