Bar code false proof card

Abstract

A bar-code anti-counterfeiting card pertains to electric card technique field, which is characterized in that two or more than two anti-counterfeiting bar-codes are provided on the main body of the card, wherein, one bar-code is the anti-counterfeiting main bar-code, the others are anti-counterfeiting auxiliary bar-codes; the anti-counterfeiting main bar-code is a bar-code in which the data has been encrypted by the preset encryption algorithm; the anti-counterfeiting auxiliary bar-codes are bar-codes that encrypt data based on the anti-counterfeiting main bar-code enciphered data or raw data; at least one of the anti-counterfeiting main bar-code and the anti-counterfeiting auxiliary bar-codes is the invisible bar-code. Compared with the prior technique, the invention has the following advantages: multiple anti-counterfeiting and good anti-counterfeiting effect; effective reduced processing costs, ensured use universality of the anti-counterfeiting card; capability of dividing the enciphered data write-in process into a plurality of stages according to different requirements due to the peculiarity that the bar-code can be printed at any moment and the radio frequency label can be read and written. The invention can be extensively used into landscape and park entrance tickets, tickets, various member cards and electric debit cards, bank cards field.

Description

Technical field: [0001] The invention relates to a bar code anti-counterfeiting card, which belongs to the technical field of electronic cards. Background technique: [0002] In recent years, with the improvement of electronic and informatization, such as scenic spots and park tickets, bus tickets, various membership cards and electronic debit cards, the usage rate of bank cards is getting higher and higher, and such cards urgently need good anti-counterfeiting effects Anti-counterfeiting technology to improve the reliability of electronic cards. At present, the anti-counterfeiting of such electronic cards generally adopts separate magnetic card data encryption and barcode data encryption for anti-counterfeiting. However, independent magnetic card data encryption and barcode data encryption still have the disadvantage of being easy to counterfeit. In addition, the anti-counterfeiting method of combining magnetic cards and invisible barcodes, such as the CN27068048Y inventi...

However, the separate magnetic card data encryption and barcode data encryption still have the disadvantage of being easy to counterfeit.

In addition, the anti-counterfeiting method of combining magnetic cards and invisible barcodes, such as the CN27068048Y invention patent announced on June 29, 2005, can improve the anti-counterfeiting level, but because the processing cost of this type of electronic car
