Safe double-frequency all-purpose card

Abstract

The invention discloses a safe double-frequency all-purpose card which comprises an encapsulation outer layer, a card base arranged in the encapsulation outer layer, a high-frequency electronic tag and an ultrahigh-frequency electronic tag. The high-frequency electronic tag and the ultrahigh-frequency electronic tag respectively comprise winding antennas and chips, and are arranged on the card base side by side at intervals. The safe double-frequency all-purpose card also comprises an isolated layer, and the isolated layer is arranged between the high-frequency electronic tag and the ultrahigh-frequency electronic tag which are arranged on the card base in an overlapping mode. The high-frequency electronic tag works in a high-frequency band and is an encrypted storage tag; a memory of the chip is provided with a plurality of sectors, each sector is divided into a data block and a cipher block, the data block is used for storing various data information, and the cipher block is used for storing cipher information. The ultrahigh-frequency electronic tag works in an ultrahigh frequency band. The invention has the advantages of accurate read with far and near distance, safety, multiple uses, and the like.

Description

Technical field [0001] The invention relates to an all-in-one card, in particular to a safe dual-frequency all-in-one card. Background technique [0002] In recent years, with the vigorous development of high technology, the market for cards has become larger and larger, and its application range has become wider and wider. There are also various forms of cards, such as barcode cards, magnetic stripe cards, and contact IC cards. The emergence of various cards depends on the development of modern information recognition technology. These various types of cards are replacing some traditional cash, keys, tickets, paper cards, etc. The appearance of these cards has indeed greatly facilitated people's work and life. [0003] At present, all-in-one cards in the prior art mainly manage personnel, objects, and vehicles through ID cards or simple logical memory cards. The cards themselves do not store any information, or store very little information, but store the main data in the backgr...

Problems solved by technology

[0004] The card has no password, once the card is lost, it is easy to cause economic loss, and the economic loss can only be borne by the user;

[0005] The card has no password, it is easy to read out the card ID for copying, and the system is extremely easy to enter;

[0006] When in use, the card reader must be connected to the Internet, and the data is called from the background, which limits the scope of use;

[0007] The card generally uses an ID card or a simple memory card, which can only store a small amount of data, and cannot realize multiple funct
