[0017] In order to fully understand the objects, features and effects of the present invention, the present invention will be described in detail below with reference to specific embodiments and drawings.

[0018] As shown in FIGS. 1 to 3, the present invention provides an electronic money card that includes at least a card body 1, a sensing and transmitting unit 2, a transaction processing control unit 3, and a display unit 4 for displaying transaction data.

[0019] The sensing transmission unit 2 is provided on the card body 1, and obtains power by sensing at least one payment device (e.g., a sensing reader / writer), and receives at least one charge signal and a deduct signal from the payment device.

[0020] The transaction processing control unit 3 is provided in the card body 1 and electrically connected to the sensing and transmitting unit 2. The transaction processing control unit 3 receives power transmitted from the sensing and transmitting unit 2 to perform functions, such as performing integrated calculations based on the charge signal and the deduction signal, and generating balance data and deduction data. The transaction processing control unit 3 may also be a microcontroller, a central processing unit, an integrated circuit chip, or a logic circuit that stores various transaction data and account information.

[0021] The display unit 4 is provided on the surface of the card body 1 and is electrically connected to the transaction processing control unit 3. The display unit 4 has a balance data display area 41 and a deduction data display area 42. It receives the balance data and the deduction data sent from the transaction processing control unit 3 and displays the balance data in the balance data display area 41 and the deduction data in the deduction data display area 42. The display unit 4 may be square, rectangular, or oval, and may be an electrophoretic display, a liquid crystal display, a cholesteric liquid crystal display, a bistable liquid crystal display, a multistable liquid crystal display, a flexible organic light-emitting diode display, a flexible light-emitting diode display, a flexible liquid crystal display, or electronic paper. The display unit 4 may also be configured to have a monochrome or color display screen according to needs.

[0022] When using the electronic money card displaying transaction data according to the present invention, first, the card main body 1 is brought close to the payment device and the sensing / transmission unit 2 senses the payment device to obtain power and provide the power to the transaction processing control unit 3. Then, at the same time that power is supplied from the payment device to the transaction processing control unit 3, the charge signal and the deduction signal are also transmitted, and the transaction processing control unit 3 performs integrated calculations based on the charge signal and the deduction signal, generates the balance data and the deduction data, and transmits them to the display unit 4. Upon receiving the balance data and the deduction data from the transaction processing control unit 3, the display unit 4 displays the balance data in the balance data display area 41 and the deduction data in the deduction data display area 42.

[0023] For example, when loading 1,000 yen onto the payment device, first, the card main body 1 is brought close to the payment device, and the sensing / transmission unit 2 is sensed by the payment device to obtain power, which is then provided to the transaction processing control unit 3. At the same time that power is provided to the transaction processing control unit 3, a charge signal indicating that 1,000 yen has been loaded is transmitted to the transaction processing control unit 3. In this case, no deduction has been performed, so no deduction signal is transmitted. The transaction processing control unit 3 performs calculations based on the charge signal indicating that 1,000 yen has been loaded, generates balance data indicating that 1,000 yen has been loaded, and transmits this to the display unit 4. The display unit 4 then receives the charge signal indicating that 1,000 yen has been loaded from the transaction processing control unit 3, displays the balance data of "1,000 yen" in the balance data display area 41, and displays the deduction data of "0 yen" in the deduction data display area 42.

[0024] Furthermore, when a transaction of 100 yen is made with the payment device, the card main body 1 is brought close to the payment device and the sensing / transmission unit 2 is sensed by the payment device to obtain power and provide the power to the transaction processing control unit 3. At the same time that power is provided to the transaction processing control unit 3, a deduction signal indicating that 100 yen has been deducted is transmitted to the transaction processing control unit 3. The transaction processing control unit 3 performs calculations based on the deduction signal indicating that 100 yen has been deducted and a charge signal (balance signal) indicating that 1,000 yen has been charged previously, generates deduction data indicating that 100 yen has been deducted and balance data of "900 yen," and transmits them to the display unit 4. The display unit 4 then receives the deduction signal indicating that 100 yen has been deducted and the balance data of "900 yen" from the transaction processing control unit 3, displays the balance data of "900 yen" in the balance data display area 41, and displays the deduction data of "100 yen" in the deduction data display area 42.

[0025] In this way, according to the above embodiment, the sensing and transmitting unit 2 can sense the payment device and obtain power, a charge signal, and a deduction signal. The transaction processing control unit 3 receives the power to perform functions, performs integrated calculations based on the charge signal and the deduction signal, generates the balance data and the deduction data, and displays them on the display unit 4. This allows data to be displayed in real time during a transaction, improving transaction convenience.

[0026] This embodiment of the present invention is similar to the above-described embodiment, but differs in that the card body 1 includes a first sheet 11, a second sheet 12, and a flexible electronic control board 13. The flexible electronic control board 13 is disposed between the first sheet 11 and the second sheet 12, and may have a circuit layout such that the sensing transmission unit 2, the transaction processing control unit 3, and the display unit 4 are located on the surface of the first sheet 11 and electrically connected to the flexible electronic control board 13. This allows the sensing transmission unit 2, the transaction processing control unit 3, and the display unit 4 to be easily integrated into the flexible electronic control board 13, and also allows the flexible electronic control board 13, including the sensing transmission unit 2, the transaction processing control unit 3, and the display unit 4, to be firmly coupled between the first sheet 11 and the second sheet 12, thereby improving the stability of the fastening.

[0027] In one embodiment of the present invention, which is similar to the above-described embodiment, the sensing-transmission unit 2 can be an induction coil or a high-frequency antenna. Therefore, the sensing-transmission unit 2 can sense the payment device without contact, and obtain current from the payment device, as well as power, charging signals, and debit signals, thereby eliminating the need for active power. This makes the present invention more practical.

[0028] In one embodiment of the present invention, which is similar to the above-described embodiment, there is a difference in that the transaction processing control unit 3 includes a transaction calculation unit 31, a transaction balance module 32 connected to the transaction calculation unit 31, and a transaction reconciliation module 33 connected to the transaction calculation unit 31. Upon receiving the charge signal and the reconciliation signal, the transaction calculation unit 31 performs decryption, encryption, and integration calculations to generate the balance data and temporarily store it in the transaction balance module 32, and generate the reconciliation data and temporarily store it in the transaction reconciliation module 33. Then, the transaction calculation unit 31 transmits the balance data in the transaction balance module 32 and the reconciliation data in the transaction reconciliation module 33 to the display unit 4.

[0029] According to the above embodiment, when loading 1,000 yen using the payment device, first, the card main body 1 is brought close to the payment device, and the sensing / transmission unit 2 is sensed by the payment device to obtain power, which is then provided to the transaction processing control unit 3. At the same time as power is provided to the transaction processing control unit 3, a charge signal indicating that 1,000 yen has been loaded is transmitted to the transaction processing control unit 3. In this case, no deduction has been performed, so no deduction signal is transmitted. The transaction calculation unit 31 of the transaction processing control unit 3 performs calculations based on the charge signal indicating that 1,000 yen has been loaded, generates balance data indicating that 1,000 yen has been loaded, temporarily stores the balance data in the transaction balance module 32, and transmits the balance data to the display unit 4. When the display unit 4 receives the charge signal indicating that 1,000 yen has been loaded from the transaction processing control unit 3, it displays the balance data of "1,000 yen" in the balance data display area 41 and the deduction data of "0 yen" in the deduction data display area 42.

[0030] Furthermore, when a transaction of 100 yen is made with the payment device, the card main body 1 is brought close to the payment device and the sensing transmission unit 2 is sensed by the payment device to obtain power and provide the power to the transaction processing control unit 3. At the same time that power is provided to the transaction processing control unit 3, a deduction signal indicating that 100 yen has been deducted is transmitted to the transaction processing control unit 3. The transaction processing control unit 3 performs calculations based on the deduction signal indicating that 100 yen has been deducted and a charge signal (balance signal) indicating that 1,000 yen has been charged, which is temporarily stored in the transaction balance module 32, to generate deduction data indicating that 100 yen has been deducted and balance data of "900 yen," which are temporarily stored in the transaction deduction module 33. The transaction calculation unit 31 then transmits the balance data in the transaction balance module 32 and the deduction data in the transaction deduction module 33 to the display unit 4. When the display unit 4 receives the charge signal indicating that 100 yen has been deducted from the transaction processing control unit 3 and the balance data of "900 yen", it displays the balance data of "900 yen" in the balance data display area 41 and the deduction data of "100 yen" in the deduction data display area 42.

[0031] In this way, the sensing and transmitting unit 2 can sense the payment device and obtain power, a charging signal, and a debit signal. The transaction processing control unit 3 receives the power to perform functions, performs integrated calculations based on the charging signal and the debit signal, generates the balance data and the debit data, and displays them on the display unit 4. This allows data to be displayed in real time during a transaction, improving transaction convenience.

[0032] In addition to the above-mentioned embodiments, another embodiment of the present invention is similar to the above-mentioned embodiments, but differs in that the balance data display area 41 and the deduction data display area 42 are arranged vertically one above the other or horizontally side by side, so that the balance data display area 41 and the deduction data display area 42 can be arranged in different patterns according to the specifications and sizes of the display unit 4, thereby meeting the needs of practical application.

[0033] In addition to the above-described embodiment, as shown in Figures 4 to 6, one embodiment of the present invention is substantially the same as the above-described embodiment, but differs in that it further includes a connection unit 5 electrically connected to the transaction processing control unit 3, which is based on a short-range communication protocol or a Bluetooth (registered trademark) communication protocol and can be connected to a communication device. This allows the transaction calculation unit 31 to be connected to the communication device via the connection unit 5, and data in the transaction balance module 32 and the transaction withdrawal module 33 to be read by accessing the communication device. This improves convenience during use.

[0034] In addition to the above-described embodiments, another embodiment of the present invention is similar to the above-described embodiments except that it further includes a power storage unit 6 electrically connected to the transaction processing control unit 3. The power storage unit 6 may be a capacitor having a capacitance of 0.1 mF to 20 mF. The power storage unit 6 receives and stores power transmitted from the sensing and transmitting unit 2 to ensure power for the transaction processing control unit 3 to function. This allows the sensing and transmitting unit 2 to rapidly charge the power storage unit 6 in a short time when obtaining power by sensing the payment device. Therefore, power is provided quickly in real time so that the transaction processing control unit 3 can perform integrated calculations based on the charge signal and the deduction signal, and generate and transmit the balance data and the deduction data to the display unit 4, improving transaction convenience.

[0035] In addition to the above-described embodiments, another embodiment of the present invention is similar to the above-described embodiments except that it further includes a power unit 7 electrically connected to the transaction processing control unit 3 and directly providing power for the transaction processing control unit 3 to function. The power unit 7 may be a primary battery or a secondary battery. As a result, when the sensing and transmitting unit 2 obtains power by sensing the payment device, it can be quickly charged in a short time by the power unit 7 or by the power unit 7 working in cooperation with the storage unit 6. Therefore, power is provided quickly in real time so that the transaction processing control unit 3 can perform integrated calculations based on the charge signal and the deduction signal, and generate and transmit the balance data and the deduction data to the display unit 4, improving convenience during transactions.

[0036] The connection unit 5, the storage unit 6, and the power unit 7 in the above-described embodiments can be installed simultaneously or separately to meet the needs of practical application and correspond to different card uses and transaction methods.

[0037] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. Therefore, the scope of protection of the present invention is as specified in the claims. [Explanation of symbols]
