DETAILED DESCRIPTION OF THE PRESENT INVENTION
The present invention is adaptable to credit card transaction, financial transaction, such as web transaction, automated teller machine, card reader, point of sales and personal identify.
Turning to FIG. 1, it illustrates a transaction card 10 including a substrate 12 formed of such as plastic material. For example, the thickness of the substrate is about 0.08 mm to 0.12 mm. Preferably, the card is dimensioned as the size of the current transaction card. The magnetic strip is optional for the embodiment.
As shown in the illustration, the transaction card includes IC 12 coupled to a display 13. The display 13 is located at anywhere of the card. The display maybe an electronic paper, OLED, FED (field emission display). For transaction card, the user information, account number, code, card numbers are stored into the IC (or memory in the IC). The IC could be a single chip, integrated chip or multiple chips. The substrate could be flexible material, transparent or non-transparent material. The IC could include memory such as FLASH memory, ROM etc. in order to store information. For example, the IC (or the memory in the IC) 12 may store transaction security code generator 14 for verification or identify. The IC (or the memory in the IC) 12 may also include includes but is not limited to account number, user information or code. The IC 12 can be integrated with the memory. The IC card 10 may include the interface 16 for communicating with the ATM or card reader by contact. The card reader may communicate with the card with/or without the interface 16. It could be applied to the point of sales (POS), ATM. The IC card could be credit card, financial card, cash card. A piezoelectric material bottom 18 is provided to activate the transaction security code generator 14 to generate the security code and provide electricity to the IC 12. The piezoelectric material bottom 18 may generate electricity while press by external force, followed by displaying the security code on the display 13. Then, the user may input the security code to the webpage displayed on the display of a computer for web transaction or ATM for verification. It is because that the piezoelectric material button 18 is used, therefore, no battery is necessary. The battery may also be optionally used. Compared to the prior art, the user may omit to carry the separated security device with the user. The transaction security code may secure the safety of the transaction after logon to the business Internet banking.
Another embodiment is almost the same with the above example except the power or electricity is provided from the card reader when the card is inserted into the card reader. In one example, the power is provided from the interface 16 to activate the transaction security code generator 14 to generate the security code. Therefore, the button 18 is also a trigger, no piezoelectric material involved in the example. Based on the improvement of the IC technology, it allows enough capacity store the credit points or electronic money, even the security code generator.
In an alternative embodiment, the transaction card is NFC card as shown in FIG. 2. The interface 16 may be optional or is implanted with the antenna 20. As shown in the illustration, the transaction card includes IC 12 coupled to an antenna (or resonant coils) 20. The antenna or resonant coils 20 is located at any where of the card. For credit card, the user information, code, card numbers are stored into the IC or memory. The transaction card may remove the magnetic strip or physical contact interface such as the pins on the card. The power or electricity may be provided from the wireless card reader from the antenna or resonant coils 20 or the physical interface 16. Therefore, the battery is not necessary.
Alternatively, the present invention may be incorporated into the SIM for the portable phone. The card includes I/O interface 16 coupled to the phone. The antenna or resonant coils 20 is a near field transaction antenna rather than the RF antenna of the phone. Therefore, the phone can be used as the transaction tool. Based on the features, the SIM may identify the user of the phone, it can be used as the code to identify the one who deals with the transaction. Therefore, users may use the phone embedded with the contactless card as the transaction tool for near field transaction. It may through the service party for example, communication service company, credit card center or bank to charge the transaction. Otherwise, it may download the credit points from the communication network or internet, the card acts as the payment tool or virtual cash card. The related information may be displayed and processed by the software in the phone or IC, therefore, the transaction record or information could be stored or displayed. The user may add the credit value into the card through a POS system or download the coupon through the communication network or Internet if the phone has the wireless module such as WiFi. It may automatically add the electronic cash value when the electronic money is below the threshold.
During the operation, the contact-less reader or POS may be supplied by power and generate magnetic field or electronic current to drive the IC for fetching the information stored in the memory. The energy transmitted by wireless may be used to drive the security code generator to generate the security code for trading or web banking service. Similarly, the card may receive the signal from the reader by electronic-magnetic effect. The coils 52 of the contactless reader 50 may transmit or receive signal to read/write device 54. A control unit 60 coupled to the read/write device to process the received or delivered signal. The coils maybe replaced by antenna. The contactless card reader or POS maybe connected to the terminal server and coupled to the control unit 60 through the internet interface 56 for interchanging the information with the database. A printing unit 58 is optional coupled to the control unit 60 in order to print the transaction receipt. Typically, the contactless or contact card reader is coupled to a computer to engage with the banking service.
The invention may be applied to ATM as shown in FIG. 3. Therefore, it is a contact-less ATM 100 including cash drawing unit and/or depositing unit 102 for drawing or depositing money. A control unit 104 is provided to control the input signal and coupled to the main frame (not shown) for transaction identification and data query. A memory 105 may couple to the control unit 104. A cash storage 106 is used to store cash and coupled to the cash drawing unit and/or depositing unit 102 through cash delivery. The contact-less ATM 100 includes a contact-less read-writer 110 coupled to the contact-less signal transmitter 112 and the control unit for near field wireless transaction. The ATM 100 will couple to the terminal for identification while transaction. It may also include the contact reader 114 for conventional usage. It may couple to the terminal database for information exchange.
