Problems solved by technology
However, magnetic stripe cards are susceptible to surrounding electromagnetic interference
The contact integrated circuit card reads and writes data by contacting the contacts of the reading and writing equipment with the contacts of the card. It has the advantages of fast speed and low cost, but it is easy to be damaged.
The non-contact integrated circuit card communicates with the reader device by means of non-contact data reading. It is easy to operate and has high security. However, it needs to be equipped with a dedicated terminal reader, which makes the cost high and is easily affected by metal materials and Limitations of the surrounding metal environment

Embodiment Construction
[0021] The following description will be made in conjunction with the accompanying drawings and specific implementation manners.
[0022] refer to figure 1 , figure 1 It is a structural diagram of an embodiment of the audio card of the present invention. In this embodiment, the audio card includes a power supply module 110 , a control module 120 and a sound module 130 . Wherein, the control module 120 is coupled to the power supply module 110 and the sound module 130 respectively.
[0023] The power supply module 110 is used to supply power to the control module 120 . Specifically, the power supply module 110 is a battery, wherein the thickness of the battery is thin enough and the volume is small enough to be installed in the battery of the audio card. In an application embodiment, the power supply module 110 is a flexible lithium-manganese dioxide battery.
[0024] The control module 120 is configured to process the identification data when the power supply module 110 su...

The invention discloses a sound card. The sound card comprises a power supplying module, a control module and a sound module, wherein the power supplying module and the sound module are respectively coupled with the control module; the power supplying module is used for supplying power to the control module; the control module is used for processing identification data; the sound module is used for performing conversion between an electric signal and a sound signal; the power supplying module supplies power to the control module, so that the control module starts to work; the control module processes the identification data and controls the sound module to be in sound signal communication with the outside. In this way, the functions of counterfeiting prevention and identity recognition or identity identification can be achieved. Meanwhile, the sound card is easy to obtain, low in cost and capable of avoiding the limit by metal material and the ambient metal environment and avoiding ambient electromagnetic interference.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to an audio card. Background technique [0002] Currently, a smart card is widely used in various fields as an identification tool, for example, as a financial card, a traffic card, a social security card, and the like. [0003] In the prior art, smart cards can be classified into contact integrated circuit cards, non-contact integrated circuit cards and magnetic stripe cards. Among them, the magnetic stripe card is widely used because it uses a liquid magnetic material or a magnetic stripe as an information carrier, and its cost is relatively low. However, magnetic stripe cards are susceptible to surrounding electromagnetic interference. The contact IC card reads and writes data by contacting the contacts of the reading and writing device with the contacts of the card. It has the advantages of high speed and low cost, but it is easy to damage. The non-contact integr...
