Embodiment 1

[0023] figure 1 It is an implementation flowchart of the data reading method provided by the embodiment of the present invention, and is described in detail as follows:

[0024] In step S101, obtain the card reader program of IC card, ID card, CPU card;

[0025] In step S102, the card reading programs of the IC card, ID card, and CPU card are separated in a componentized manner;

[0026] Among them, the card reading programs of IC card, ID card and CPU card are separated by adopting componentization, so that the card reading programs of IC card, ID card and CPU card do not interact with each other. When the card reading program of the IC card and the card reading program of the ID card are shielded, the card reader can also read the CPU card.

[0027] In step S103, the pre-configured polling sequence is used to call the card reading programs of the IC card, ID card, and CPU card to poll for card reading.

[0028] Wherein, before step S103, a polling sequence is configured, ...

Embodiment 2

[0037] figure 2 It is the implementation flowchart of step S103 of the data reading method provided by the embodiment of the present invention, and is described in detail as follows:

[0038] In step S201, when the card reader or card issuer detects a card, a card reading event is triggered;

[0039] In step S202, according to the card reading event, the pre-configured polling sequence is used to call the card reading programs of the IC card, ID card, and CPU card, and poll the cards in turn.

[0040] Wherein, the card-reading event is used as a trigger condition, and the card-reading event is monitored at the card reader or card issuer. When a card-reading event occurs, the pre-configured polling sequence is used to call the card-reading of the IC card, ID card, and CPU card. Program, polling card reader in turn.

[0041] For example, when a card is placed on the card reader or card issuer, the card reading event is triggered, and the card reading program is started to run...

Embodiment 3

[0044] This embodiment describes the implementation process of turning on the identification lamp, which is described in detail as follows:

[0045] When reading the card, the card mark in the card is read, and the identification light corresponding to the card mark is turned on according to the card mark.

[0046] Wherein, the card type mark is a mark of a card type, and the card type mark includes IC, ID, and CPU.

[0047] Mark IC, ID and CPU in the card reader respectively. When the user swipes the card, when the type of the card is IC, the corresponding identification light of IC will be on; when the type of the card is ID, the corresponding identification light of ID will be on. When the type of the card is CPU, the indicator light corresponding to the CPU is on.

[0048] In this embodiment, lighting up the identification light corresponding to the card type mark not only facilitates the user to know the type of card he is using, but also facilitates the verification, an...

Abstract

The invention is applicable to the technical field of data reading and provides a data reading method and device. The data reading method comprises the steps that a card reading program of IC cards, a card reading program of ID cards and a card reading program of CPU cards are acquired; the card reading program of the IC cards, the card reading program of the ID cards and the card reading program of the CPU cards are divided in a modularization mode; according to a pre-configured polling sequence, the card reading program of the IC cards, the card reading program of the ID cards and the card reading program of the CPU cards are called for reading the cards in a polling mode. The data reading method and device have the advantages that on one hand, delay of program execution can be prevented; on the other hand, the robustness of the programs can be increased; therefore, the problems that data are misread and can not be read out due to the fact that the data reading speed and the data reading reliability are low through existing data reading methods of card readers or card senders are solved; on the condition that the card readers or the card senders are used normally, the data reading speed is increased, and the data reading reliability is also improved.

Description

technical field [0001] The invention belongs to the technical field of data reading, and in particular relates to a data reading method and device. Background technique [0002] At present, it is very common to hold cards in passages, parking lots, access control and other fields. Usually, the data reading method of a card reader is used to read the information in the card to pay for parking fees. According to the different packages selected by users and temporary use, the types of cards they hold are also different. At present, IC cards, ID cards, and CPU cards are more popular. [0003] However, the data reading method of the existing card reader or card issuer has slow data reading speed and low reliability of reading data, and it is easy to read wrong data or fail to read data. Its reason is that existing usually adopts compatible card issuer or card reader, promptly a card issuer or card reader can read the data in IC card and can read the data in ID card, CPU card, an...
