Embodiment Construction

[0027] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples.

[0028] The present invention proposes a logical encryption card offline transaction data processing method and device, which is a method for storing and processing offline transaction data by a logical encryption card in an offline transaction scene. Among them, offline transaction refers to the behavior that the transaction system consumes or recharges according to the balance information of the electronic wallet built in the card, and updates the balance in the card.

[0029] The embodiment of the present invention provides a logical encryption card offline transaction data processing method, ...

Abstract

The invention provides an off-line transaction data processing method of a logic encryption card, which comprises the steps that off-line balance information and recent off-line transaction detail information are read, wherein the off-line balance information and the recent off-line transaction detail information comprise check codes; whether the check codes of the off-line balance information and the recent off-line transaction detail information are correct is checked; and data recovery processing is performed according to a check result. The invention further provides an off-line transaction data processing device of the logic encryption card. With the adoption of the technical scheme, purposes of off-line historical transaction information query, balance backup and data damage prevention due to card extraction are achieved under the condition that a storage space of the logic encryption card is not required to be occupied additionally.
