Embodiment Construction

[0045] The method provided by the present invention is mainly designed for the situation that the transaction time is relatively short and the card needs to return the transaction authentication code (TAC) and MAC (Message Authentication Code, message authentication code) 2 necessary for the PBOC specification. Utilizing the transaction process provided by the present invention can effectively shorten the consumption instruction time of dual-interface smart cards or pure non-contact smart cards or contact CPU cards, etc. Wait.

[0046] In the following, as shown in FIG. 3 , a detailed description will be given by taking the OBU scheme of the expressway non-stop toll collection system as an example.

[0047] As mentioned above, the key to shortening the smart card transaction time is to make the "time period II" meet the time requirements of the ETC system. The reasons for requiring the shortest possible time period II can be summed up in the following four points:

Abstract

This invention provides one method to contract electron currency consumption trade time, which comprises the following steps: dividing the consumption process into pre-consumption order and payoff order; after initiating consumption, first computing first message identification codes to execute one pre-consumption order; the order feeds back trade identification codes and second message identification codes and to put to payoff position; the payoff order fulfills the operations of user card pay and updating record according to label bit.

Description

technical field [0001] The invention relates to a method capable of effectively shortening the consumption and transaction time of electronic money based on carriers such as smart cards, and belongs to the technical field of financial electronics.
