Problems solved by technology

Similarly, the existing chip 23 also has a security problem similar to that of the ink cartridge chip, that is, the encryption function only uses the serial number data of the radio frequency chip as a parameter to calculate the password verification value. Once the serial number data is customized and the password verification value is copied, Will affect the safety of a range of products

[0037] The radio frequency chip of this embodiment has a substrate, and the antenna used for wireless communication with the laser printer is provided on the substrate, and a memory electrically connected with the antenna is provided, and the storage structure of the memory is as follows: Figure 4 shown.

[0038] The serial number data 31 of the radio frequency chip is stored in the memory 30, and the serial number data 31 is an identification code of each radio frequency chip, which cannot be modified and is not repeatedly set, and has uniqueness.

[0039] The memory 30 also stores a plurality of data related to the toner cartridge, including the number of pages 32 that can be printed on a standard page by the initial amount of toner in the toner cartridge, the applicable country code 33 for the toner cartridge, and the production date of the toner cartridge. Serial number 34, model number 35 of the toner cartridge, etc. These data can be fixed before the production of the t...

[0046] Same as the first embodiment, this embodiment has a substrate, and the substrate is provided with interconnected antennas and memory, and the storage structure of the memory is as follows: Figure 5 shown.

[0047] The memory 30 stores the serial number data 31 of the radio frequency chip, the remaining amount of toner 36, and a plurality of toner cartridge-related data, including the initial toner amount in the toner cartridge, the number of pages that can print standard pages 32, the country code 33, The serial number is 34 and the toner cartridge model is 35. A password verification storage area 37 is provided in the memory 30, and a first password verification value 38 is stored, which will not be repeated here.

[0048] Different from the first embodiment, the second password verification value 39 is also stored in the password verification storage area 37 of the present embodiment. The second password verification value 39 only uses the serial number data 31 (UID...

Abstract

The invention provides a radio frequency chip, a consumable material container, a data writing method and a verifying method. The radio frequency chip comprises a base plate, wherein the base plate is provided with an antenna and a memorizer connected with the antenna; the memorizer memorizes serial number data of the radio frequency chip and the consumable material-correlated data; the memorizer is provided with a password verifying and memorizing region; and the password verifying and memorizing region memorizes a first password verifying value which is computed by taking the serial number data and the consumable material-correlated data as parameters. The data writing method of the radio frequency chip comprises the following steps of: reading the serial number data of the radio frequency chip; writing the consumable material-correlated data into the memorizer; computing to obtain the first password verifying value though a first encrypting function by taking the read serial number data and the written consumable material-correlated data as the parameters; and writing the first password verifying value into the password verifying and memorizing region. The invention is convenient for a printer to identify the consumable material container, and improves the whole safety of the consumable material container.

Description

technical field [0001] The invention relates to a chip, in particular to a radio frequency chip mounted on a printing consumable container, a consumable material container equipped with the radio frequency chip, a data writing method and a verification method of the radio frequency chip. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to provide printers with printing ink to form characters or patterns that need to be printed on paper; The toner cartridge with toner is used as a consumable container to provide the printer with toner for printing to form text or patterns that need to be printed on the medium. [0003] see figure 1 , The existing ink cartridge has a housing 11, the housing 11 encloses a cavity 15, and the cavity 15 contains ink. One wall of the casi...
