Currency label and anti-counterfeit method thereof

A currency and tag technology, which is applied in the authenticity inspection of banknotes, handling coins or valuable banknotes, instruments, etc., can solve the problems of reducing the reading and writing distance of tags, limiting the use, and low real part of antenna impedance, achieving radiation performance and Improved impedance conjugate matching performance, excellent impedance conjugate matching, and the effect of increasing the reading range

Problems solved by technology

[0005] (1) Since there are no two arms of the antenna, the real part of the antenna impedance is extremely low, and good impedance conjugate matching with the chip cannot be achieved; the reading and writing distance of the tag is severely reduced;
[0006] (2) Since there are no antenna arms, it can only work by means of electromagnetic field near-field coupling
The working method determines that the tag can only be read and written at a short distance, and the reading distance can only be within a range of less than 10cm, which greatly limits the application of this solution

Embodiment 1

[0032] Embodiment one: if figure 1 As shown, the present invention includes a currency 1, a metal strip 2 and a ring label 3, the metal strip 2 is arranged on the currency 1, and is parallel to the shorter side of the currency 1, the ring label 3 is arranged on one side of the metal strip 2, and the ring The central axis of the label 3 is on the same straight line as the center of the metal strip 2, the distance between the side of the ring label 3 close to the metal strip 2 and the side of the metal strip 2 close to the ring label 3 is 1.6mm, and the ring label 3 is rectangular , which is 18mm long and 16mm wide. The currency 1 anti-counterfeiting method includes the factory ID of the ring chip 3: the ID number of the ring chip 3 is written when the ring chip 3 leaves the factory, and each ring chip 3 has a unique factory ID number, which cannot be changed; Use the unique ID number owned by the currency to be written in the database; Encrypted database: Encrypted informatio...

Abstract

The invention discloses a currency label and an anti-counterfeit method thereof. The currency label comprises a currency, a metal strip and a circular label, wherein the metal strip is arranged on the currency and parallel to a shorter side of the currency, and the circular label is arranged on one side of the metal strip. According to the currency label and the anti-counterfeit method thereof, a circular chip is arranged on one side of the metal strip of the currency; the metal strip is taken as an antenna of the circular chip, so that information in the circular chip can be read in a longer distance; and counterfeit prevention for the currency is performed through the factory ID of the circular chip, the paper currency ID written in the circular chip and enciphered information, so that currency authenticity can be detected in large batches, and the detection is more accurate.

Description

technical field [0001] The invention relates to an anti-counterfeit currency, in particular to a currency label and an anti-counterfeit method thereof. Background technique [0002] Renminbi is the legal tender of my country. The fifth set of RMB in 1999 and 2005 is mainly circulated in the market. Compared with the previous versions of RMB, the main features are as follows: First, it highlights the "three major" features. That is, large portraits, large watermarks, and large denomination numbers are not only easy to identify, but also enhance the anti-counterfeiting function; the second is to cancel the traditional frame design of banknotes in the past, and the banknotes have an open structure, which increases the anti-counterfeiting design space; the third is the main scene on the back The method of combining landscapes reflects Chinese characteristics; fourth, the face is simple, with clear lines and bright colors; fifth, machine-reading technology is added to facilitate...
