Embodiment Construction

[0171] The application structure of the non-contact logical encryption card of the present invention comprises:

[0172] An electronic wallet, which has an original and a copy;

[0173] ●Historical transaction record area, which records the latest N transactions in the form of circular queue

[0174] transaction, and indicate the most recent transaction through the transaction pointer, which includes

[0175] Transaction balance, transaction amount, terminal card number, terminal transaction serial number, transaction date

[0176] period and other information;

[0177] ●Public information area, used to store transaction pointers, card transaction counts, etc., which can

[0178] Mutual back-up originals and copies;

[0179] The transaction record format of the present invention is provided with a transaction state identifier, which is used to describe the state of the electronic wallet when the transaction occurs.

[0180] The non-contact logical encryption card ...

Abstract

The ivnention relates to a processing method of non-contact typed logic encryption card with terminal against pulling out. The method includes following steps. First, identical indicator of dealing state is set for both of electric wallet account of the encryption card and account of dealing clearance system. Then, an indicator of dealing state is set on the electric wallet account of the encryption card in order to determine whether the dealing is successful or not, and undetermined flow of dealing process. Finally, an indicator of dealing state is set on the dealing clearance system in order to determine whether the dealing is successful or not, and undetermined flow of dealing process. Since the state of the electric wallet is directly used as the indicator of dealing state, thus the invention provides features of simple and clear flow, fast executing speed and dealing

Description

technical field [0001] The invention relates to a non-contact IC card terminal pull-out prevention processing method. Background technique [0002] Contactless IC card refers to a proximity card (PICC Proximity Integrated circuit(s) card) in compliance with the international standard ISO / IEC-14443, an ID-1 type card with integrated circuits and coupling tools on it, and integrated with The communication of the circuit is completed by inductive coupling with the adjacent coupling device); the non-contact IC card terminal refers to the proximity coupling device (PCD Proximity coupling device, which uses inductive coupling to the adjacent The card provides energy and controls the read / write device for data exchange with adjacent cards); the specific definitions of PICC and PCD refer to the ISO / IEC14443 standard text. [0003] The communication between the non-contact IC card and the non-contact IC card terminal adopts radio frequency, and the effective distance is about 10cm. ...
