Special radio frequency identification tag for leather industry

Abstract

The invention relates to the electronic industry, in particular to a radio frequency identification tag special for the leather industry, which comprises a PET (polyethylene terephthalate) layer, an adhesive layer and release paper; the PET layer is internally provided with an antenna and a chip; the antenna is connected with the chip; the antenna comprises a coil and a loop antenna. One end of the loop antenna is connected with the coil, and the other end of the loop antenna is connected with the chip; the identification frequency of the antenna in the air is 890-950 MHz, and when the antennais arranged in the leather product, the identification frequency of the antenna is 920-925 MHz; the method has the beneficial effects that the identification frequency in the leather product production process is stabilized, and the reading distance is not increased due to deviation of a leather product; the radio frequency identification tag is high in wear resistance and long in service life, is widely applied to the industries of leatherware, cases and shoes, and provides better anti-counterfeiting and anti-channeling, supply chain management, store management, warehouse management and other solutions for the leatherware, the cases and the shoes.

Description

technical field [0001] The invention relates to the electronics industry, in particular to a special radio frequency identification tag for the leather goods industry. Background technique [0002] Antenna is a component used to transmit or receive electromagnetic waves in radio equipment. It converts the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or transforms an electromagnetic wave propagating in an unbounded medium into guided wave. [0003] Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets through radio signals and read and write related data without the need to establish mechanical or optical contact between the identification system and specific targets . RFID products in different frequency bands will have different characteristics. T...

AI Technical Summary

Problems solved by technology

[0004] After ordinary UHF passive products are attached to the interior of leather products, the frequency will shift, which is directly manifested as a decrease in the reading distance: the current RFID antenna of the same size on the market, the general reading distance in the air is 1 ~1.5m, the reading distance is reduced to 0.5~1m after being implanted into the leather product, which cannot meet the requirements of use; in the process of leather product production, due to insufficient welding strength of the chip and antenna, and lack of physical protection, resulting in the use of It is easy to be damaged by external force during the process; due to improper use of self-adhesive, it will lead to glue overflow, degumming, etc., resulting in defective leather products
