Capacitance-type information identifying system

Abstract

The invention relates to a capacitance-type information identifying system which utilizes a capacitance induction principle to identify corresponding information in an information storage device. The system has a simple method, is rapider for a user to use by putting a memory card on a card reader, saves time to a certain extent and resists abrasion by arranging a conductive medium in the memory card to have stabler performance, thereby effectively prolonging the service life of the memory card, objectively saving materials and avoiding unnecessary waste. Moreover, the capacitance-type information identifying system is hardly interfered by external environment, thereby having higher confidential performance.

Description

Technical field [0001] The invention relates to an information recognition system, in particular to a capacitive information recognition system. Background technique [0002] At present, people’s common information identification systems use magnetic methods to store personal information and other prescribed password information in various cards such as credit cards and cash cards. Generally, the above information is stored in the magnetic strip of the card and then used The card reader scans the magnetic stripe on the card, and has read all kinds of information recorded on the card. Although this magnetic method also achieves the purpose of identifying information, some failures often occur in actual use, such as If the card is accidentally bent, the magnetic strip on it can no longer continue to work, or if the card is used for too long, the side strip on the card will gradually lose its magnetism. Therefore, in such cases, if the user puts the magnetic card on the card reader...

Problems solved by technology

[0002] At present, people's common information identification systems use magnetic methods to store specified password information related to personal information in various cards such as credit cards and cash cards. Generally, the above information is stored in the magnetic strip of the card, and then used The card reader scans the magnetic stripe on the card and has read all kinds of information recorded on the card. Although this magnetic method also achieves the purpose of identifying information, some failures often occur in actual use, such as If the card is accidentally bent, the magnetic strip on it will no longer work, or if the card is used for a long time, the side strip on the card will gradually lose its magnetism

So in this case, if the user puts the magnetic card on the card reader again, the card reader cannot read any data, and the magnetic card can only be invalidated at this time, which must waste materials and cause certain pollution. Or the user needs to try multiple times to get it to work, so time must be wasted

Of course, there is also a card that stores various password information in an ultra-small IC (integrated circuit) chip on the market. Since this radio wave method is susceptible to external interference, it has poor confidentiality performance and is not suitable for fields with high confidentiality, and it is not easy to apply this method to cards with user personal information recorded.
