Method and system for verifying authenticity of thermal transfer ribbon cartridge on thermal transfer printing device

Abstract

The invention provides a method and a system for verifying authenticity of a thermal transfer ribbon cartridge on a thermal transfer printing device, and is applied to the anti-counterfeiting technology of the thermal transfer printing device. The technical scheme is mainly that, sequence information in an RFID tag is read by a controller through a reader, a first encryption algorithm is used and the sequence information is used as an encryption key for performing calculation to obtain a first verification password, and the first verification password is outputted; then the RFID tag receives the first verification password and checking if the first verification password is consistent with a first password preset in the RFID tag, if yes, anti-counterfeiting verification is completed; and if not, the process goes through a verification failure processing mechanism. The method and the system are advantageous in that, the anti-counterfeiting function of the thermal transfer ribbon cartridge on a printing machine without an anti-counterfeiting function can be achieved via small modification, and therefore, a counterfeit producer does not easily crack the password, and defects of a wired anti-counterfeiting method in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting of printing equipment, in particular to a method and system for verifying the authenticity of a carbon ribbon cassette on thermal transfer printing equipment. Background technique [0002] Ribbon is a consumable that is often replaced when thermal transfer printers are in use. Generally, the printer manufacturer installs it in the ribbon box and provides it to the user for matching with the printer. Due to the huge demand for carbon ribbon cassettes, many unscrupulous producers counterfeit and counterfeit carbon ribbon cassettes, causing huge losses to the original manufacturers. At the same time, it is not easy to distinguish the authenticity of the counterfeit ribbon cassettes. These counterfeit ribbon cassettes cannot be well compatible with the printer, which can easily cause damage to the printer's hardware, and the printing quality is not up to standard, thereby affecting the rep...

AI Technical Summary

Problems solved by technology

Due to the huge demand for carbon ribbon cassettes, many unscrupulous producers counterfeit and counterfeit carbon ribbon cassettes, which caused huge losses to the original manufacturers.

At the same time, it is not easy to distinguish the authenticity of the counterfeit ribbon cassettes. These counterfeit ribbon cassettes cannot be well compatible with the printer, which can easily cause damage to the printer's hardware, and the printing quality is not up to standard, thus affecting the reputation of the original manufacturer.

[0003] Most of the existing anti-counterfeiting technologies use a wired connection to connect the anti-counterfeiting module on the ribbon cartridge. The realization of this method needs to leave a contact shrapnel on the printer core that communicates with the anti-counterfeiting module on the ribbon cartridge. This is to a certain extent Limit the structure of the printing core

In addition, due to the limitation of some printer cores, the contact shrapnel cannot be provided, so the anti-counterfeiting verification method of this wired connection cannot be adopted.
