Smart card information processing method and device

Abstract

The invention discloses a smart card information processing method and device. The method comprises the following steps: sending a signal for establishing communication connection every a first time period, and if successfully establishing connection with a second wireless communication module of mobile terminal equipment and determining that the mobile terminal equipment is pre-bound appointed mobile terminal equipment through authentication, writing an activation maintaining instruction into a standard chip; when detecting that a card reader performs a read-write operation on a smart card through a contact-type operation interface and / or a non-contact-type operation interface, detecting a time difference between the time for writing the activation maintaining instruction and current time; if determining that the time difference is greater than a preset time threshold value, sending a card locking request to the standard chip, so that the standard chip enters a card locking state. Through the smart card information processing method and device, information of the lost multi-interface smart card can be prevented from being stolen and swiped.

Description

technical field [0001] The present application relates to the technical field of smart card information processing, in particular to a smart card information processing method and device. Background technique [0002] In today's information age, smart cards play a very important role in people's lives, such as access control cards, bank cards, bus cards, etc. are closely related to people's daily life. [0003] Traditional smart cards are generally divided into two types: single-interface cards and dual-interface cards. The so-called single interface means that the way of information exchange between the smart card and the outside world is contact or non-contact. Among them, the contact smart card generally uses the ISO7816 standard, that is, an IC card with 8 metal contacts. Contactless smart cards generally use NFC or RFID standards, and use passive electromagnetic coils to communicate with the outside world. [0004] The so-called dual-interface card refers to a card w...

Problems solved by technology

[0007] However, while using the above-mentioned smart card to bring convenience to people's daily life, there may also be the following problems: in practical applications, the user's smart card may be lost and may be picked up by other users

At this time, regarding the wireless communication module on the smart card, because it needs to be read and written through the terminal device that has a binding relationship with the smart card, and a smart card can only be bound to one terminal device, therefore, as long as the user does not use the smart card Lost together with the terminal device to which it is bound, the person who finds it generally cannot read and write the smart card through this method

However, since the smart card also has other read and write operation interfaces, such as traditional contact and / or non-contact interfaces, at this time, the smart card will face the risk of being stolen.
