However, the existing smart card can only display the information in the card on the POS machine. Thus, the user cannot determine the amount of money consumed and the balance in the card after the transaction. Once the wrong amount is swiped or the sum is not swiped, unnecessary trouble is brought to the user. For example, when a user uses a subway card to swipe the card through a gate, the user is not really successful in transaction. The user can not know the card by himself, and the user is mistakenly given the fact that the card swiping is finished due to the closing delay of the gate. When the user uses the card for the next time, the user needs to go to a manual window to swipe the card to complete the previous transaction, and the amount of money to be deducted is more.
This necessarily reduces the user experience. In addition, there is also a smart card that uses electronic paper to realize the display function, but because of the slow response speed, slow conversion speed, complex manufacturing process and higher cost, it has not been widely popularized in the smart card field.
Therefore, the visual smart card is provided, which can not only display the transaction balance, but also display the transaction process, and is convenient for the user to check whether the transaction is successful, and the technical problem to be solved by the application is solved.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Embodiment 1 of the utility model provides a visual smart card, specifically as shown in fig. 1, this visual smart card includes: the device comprises amain control module 10, a near field communication module 20, adisplay module 30 and apower supply module 40;
thepower module 40 is electrically connected with themain control module 10, the near field communication module 20 and thedisplay module 30, and is used for supplying power to themain control module 10, the near field communication module 20 and thedisplay module 30;
themain control module 10 is also electrically connected with the near field communication module 20 and thedisplay module 30;
the near field communication module 20 establishes communication connection with external electronic equipment and is used for transmitting transaction information;
themain control module 10 is used for executing a corresponding transaction process according to the transaction information;
and thedisplay module 30 is used for displaying the transaction process and the balance after the transaction.
Specifically, thepower module 40 is electrically connected to all other modules in the visible smart card, and is used for supplying power to the other modules, so that the other modules can work normally. Themain control module 10 is mainly electrically connected to the near field communication module 20 and thedisplay module 30. The near field communication module 20 is configured to perform a corresponding transaction process according to the transaction information after establishing a communication connection with an external electronic device and forming the transaction information. The main control module is actually an integrated chip with a processing function, such as a CPU. The near field communication module 20 is composed of a near field communication antenna and a card chip. The power supply module can be a conventional power supply circuit, or a power supply with a power supply function, and the like. The user can use the visual smart card to consume on the corresponding matched consumption device (external electronic device). In fact, the near field communication module 20 also needs to transfer identity information between themain control module 10 and the consumer device for authentication of rights and the like. The specific processes of verifying the authority and executing the transaction are prior art and will not be described herein. Thedisplay module 30 displays the transaction process and the balance after the transaction. The transaction process can comprise the current amount in the card and the transaction amount needing to be deducted; and may display whether the transaction was successful, etc.
Through the mode, the user can check the transaction process and the month after the transaction in the transaction process, the convenience of the user when using the intelligent card is greatly improved, and the user experience degree is improved. However, if the user does not wish to view the card balance more than just during the transaction. But rather wants to view the amount of money in the card at any time. Then, the visual smart card introduced in the present application may further include: atouch module 50. Specifically, as shown in fig. 2, fig. 2 shows another schematic diagram of a visual smart card structure.
Thetouch module 50 is electrically connected to themain control module 10 and thedisplay module 30, respectively. When thetouch module 50 detects an external touch pressure and the touch time is less than a preset time threshold, a first capacitance signal is generated. For example, the preset time threshold is 5 s. The first capacitance signal is understood to be a trigger signal. After receiving the first capacitance signal, themain control module 10 obtains the remaining amount in the card according to the first capacitance signal, and displays the remaining amount through thedisplay module 30.
Therefore, the user can check the balance in the card at any time and any place.
Further alternatively, considering that if the smart card includes the nfc module 20, the amount of money in the card may be illegally consumed as long as the information in the card is likely to be read within the sensing area of the card reading device, which may result in a loss to the user in terms of information security and finance. In view of this problem, thetouch module 50 and themain control module 10 of the present application may also perform another function. The method comprises the following specific steps:
when thetouch module 50 detects the external touch pressure and the touch time is greater than or equal to the preset time threshold, generating a second capacitance signal and sending the second capacitance signal to themain control module 10;
and themain control module 10 executes self-locking operation on the visual smart card according to the second capacitance signal.
The self-locking operation performed here includes two types, and in one case, if the visible smart card is in a locked state, the operation performed is an unlocking operation. Indicating that the user wishes to unlock the smart card and complete the transaction. In another situation, where the visual smart card is in an unlocked state, it is desirable to secure the information and property of the visual smart card, and the locking operation is performed.
Further alternatively, thetouch module 50 may be composed of a touch key sheet and conductive foam. The touch key sheet is mainly used for receiving external touch pressure, and a user of the conductive foam generates a capacitance signal according to the touch pressure.
Optionally, themain control module 10 is in a low power consumption state before receiving the transaction information sent by the near field communication module 20;
after receiving the transaction information sent by the near field communication module 20, switching from the low power consumption state to the normal working state; and executing corresponding transaction process according to the transaction information
Further optionally, when the visual smart card further includes atouch module 50, before receiving the first capacitance signal or the second capacitance signal sent by thetouch module 50, themain control module 10 is in a low power consumption state; until receiving the first capacitance signal or the second capacitance signal sent by thetouch module 50, switching from the low power consumption state to the normal working state; and acquiring the balance in the card according to the first capacitance signal, or executing self-locking operation on the visual smart card according to the second capacitance signal. In this application, themain control module 10 is actually in a low power consumption state all the time when no operation is performed. Thedisplay module 30 is in an inactive state. When themain control module 10 receives the transaction information sent by the near field communication module 20 or the capacitance signal sent by thetouch module 50, the low power consumption state is changed to the normal operating state. And when thedisplay module 30 is required to display, thedisplay module 30 is controlled by themain control module 10 to start the working state. The processing sections referred to in this application are conventional and will not be described in great detail. In this way, power consumption can be further reduced.
Further optionally, thedisplay module 30 may be one or more of the following according to actual needs: an organic light emitting diode OLED display screen, a liquid crystal display screen, a full-transmission type liquid crystal display screen, a reflection type liquid crystal display screen or a semi-transmission type liquid crystal display screen.
Further optionally, the visual smart card further comprises: a card housing (not shown). Themain control module 10, the near field communication module 20, thepower supply module 40 and thetouch control module 50 are all installed in the card shell; thedisplay module 30 is mounted at a predetermined position on the surface of the card housing, for example, at an intermediate position on the upper surface of the card housing, so as to facilitate the user to view the display information.
