Embodiment one
The embodiment of the present invention one provides a kind of intelligent card data read method, and process is as shown in Figure 1, include following step
It is rapid:
Step S101: card-reading apparatus detects smart card.
User have information in reading smart card (electronic driving card, electronics driving license) (such as Pilot Name, driver license number,
License plate number, type of vehicle etc.) demand when, insert the smartcard into card-reading apparatus or close to card-reading apparatus, card-reading apparatus inspection
Measure smart card insertion or close to when, start follow-up data read operation.
Step S102: card-reading apparatus and smart card carry out file storage unit matching.
It include a certain number of file storage units in smart card, storing data information also includes certain in card-reading apparatus
The file storage unit of quantity stores corresponding decoded information.Each data information file storage unit is corresponding with corresponding solution
Code message file storage unit, corresponding relationship can be pre-set, and is stored in card-reading apparatus or smart card.
When carrying out file storage unit matching, card-reading apparatus obtains depositing for K file storage unit for including in smart card
L file storage unit decoded information item for including in storage item of information and card-reading apparatus；It is corresponding according to each storage item of information
Decoded information item determines the file storage unit in card-reading apparatus in the corresponding smart card of each file storage unit.
As shown in Fig. 2 be smartcard file storage unit schematic diagram, include in smart card 1A0,1A1,1A2 ..., 1A
(k-1), 1A (k), 1A (k+1), 1A (k+2) ..., the K file storage unit such as 1AK, store in each file storage unit
One storage item of information, storage item of information can be at least one in following message: Pilot Name, driver license number, license plate
Number, type of vehicle.Obtaining includes K file storage unit in smart card, and each file storage unit stores a motor vehicle and drives
The information (such as Pilot Name, driver license number, license plate number, type of vehicle) of person's of sailing (motor vehicle).With kth (k ∈ K) a file
For storage unit, this document storage unit includes M byte position, a certain item information in motor vehicle driving license (driving license)
It will be stored in the form of Serial No. in a byte position m to m+p (m+p≤M) of k-th of file storage unit.
