Non-contact IC card and method capable of effectively marking, identifying and cancelling

Abstract

The invention discloses a non-contact IC card and a method capable of effectively marking, identifying and cancelling, and the method comprises the steps: setting a write-in frequency limiting regionin a memory of the non-contact IC card, and storing a state code which represents the state information of a card certificate in a background database or once the card certificate is in the backgrounddatabase; enabling a verification device to read, perform networking verification, compare the networking verification with a database, and automatically rewrite the state code in the card under a set rule; and enabling the database to store the latest state information of the card holder corresponding to the card certificate. The method effectively realizes marking, identification or logout ofthe card certificate in abnormal states such as failure, loss reporting and early warning, and solves the problems of troubles and potential loss of loss reporting and failure card certificates to lost people, certificate using units, public security departments, judicial departments and the like, timeliness of interception of the lost card certificate by the early warning card certificate and thelike. The method is suitable for non-contact IC cards such as resident identity cards, electronic passport, driving licenses, motor vehicle driving licenses, financial cards, campus cards, entrance guard cards and identity recognition cards.

Description

technical field [0001] The invention relates to a non-contact IC card and a method capable of effectively marking, identifying and canceling it, and belongs to the technical field of non-contact IC cards. Background technique [0002] Non-contact IC card (also known as radio frequency card, for the convenience of description, hereinafter also referred to as card card), is composed of integrated circuit chip including memory, induction antenna, packaging shell, etc., and the verification device is used to complete the data through radio waves. It is widely used in the identification of personnel, animals, equipment, devices, etc., or in fields such as finance, public transportation, medical care, campus card, access control, etc., such as resident ID card, electronic passport, driver's license , motor vehicle driving license, financial card, campus card, access control card, identification card, etc. [0003] However, due to the characteristics of near-field (generally 5-10c...

AI Technical Summary

Problems solved by technology

For example, some plans design a network query platform to query the card issuance date, and some plans assign unique codes to each card to distinguish reissued cards, etc., but the report of loss, invalidation, and early warning card itself It still cannot be marked or canceled, and it can still be illegally used again and again, and there are still difficulties in verification and management
