Abstract
The utility model discloses an electronic paper smart card. The smart card comprises a microprocessor, a communication unit, a memory and an integrated circuit chip of a display control circuit, as well as an electronic paper display connected with the display control circuit, and is characterized in that the microprocessor is used for processing data from the integrated circuit chip and displaying the processed data on the electronic paper display. The smart card provided by the utility model is light and thin, and can display the balance and other information with low power consumption and maintain the displayed data after the power supply is cut off.
Description
Technical field
The utility model relates generally to a kind of smart card.
Background technology
Smart card comprises contact intelligent card, contact type intelligent card and double-interface card.Contact intelligent card contacts the read-write of laggard line data with the contact of smart card by the contact of read-write equipment for smart card.International standard ISO7816 has carried out strict regulation to the mechanical property of this type of card, opering characteristic of electric apparatus etc.Contact type intelligent card and smart card device do not have circuit contacts, but read and write (as light or wireless technology) by contactless read-write technology.Its embedded chip has increased RF transmit-receive circuit except CPU, logical block, storage unit.International standard ISO10536 series has been set forth the regulation to contact type intelligent card.Such card generally is used in and uses the occasion frequent, that quantity of information is less relatively, reliability requirement is higher.Double-interface card is combined to contact intelligent card and contact type intelligent card in the card, and operation is independent, but can shared CPU and storage space.But common smart card does not have information such as display, inconvenient user's reading balance amount.Therefore, need a kind of smart card that can show remaining sum in the art with very little electric weight.
Divergence form display devices such as LCD can be own luminous, so even also can normally use under the condition of dim light.But, increase along with ambient light intensity, the display effect of this display is just so not satisfactory, because stronger surround lighting has improved melanic brightness and reduced contrast, this also is we can't see literal on the display clearly under the situation of sunlight direct projection a reason.And Electronic Paper is come display image as a kind of reflective display by reflect ambient light, the brightness meeting of image changes according to the intensity of ambient light, and contrast also can change thereupon, so the advantage of reflective display is more obvious under intense light, is more suitable for human eye and reads.
The utility model content
The utility model discloses a kind of smart card, comprise have microprocessor, communication unit, storer and the integrated circuit (IC) chip of display control circuit and the electric paper display that is connected with described display control circuit, it is characterized in that: described microprocessor processes is from the data of described integrated circuit (IC) chip, and it is presented on the described electric paper display.This smart card not only quality is frivolous but also can show information such as remaining sum with very little power consumption ground, and still can keep shown data after power-off.
Integrated circuit (IC) chip can be the radio frequency discrimination RFID chip, wherein the radio frequency discrimination RFID chip be wrapped in the smart card and with the card reader wireless coupling, and communication unit is the RFID communication unit.Integrated circuit (IC) chip also can be a client identification module SIM card core, wherein client identification module SIM chip during one side is exposed on the smart card at least and with the card reader wired connection, and communication unit is the SIM card communication unit.Communication unit also can be the NFC communication unit.
Description of drawings
Fig. 1 shows the structural drawing with smart card of electric paper display of the present utility model.
Embodiment
Fig. 1 shows the structural drawing with smart card of electric paper display of the present utility model.Smart card shown in Figure 1 comprise have microprocessor, communication unit, storer and the integrated circuit (IC) chip of display control circuit and the electric paper display that is connected with described display control circuit.Microprocessor processes is from the data of integrated circuit (IC) chip, and is presented at it on electric paper display and is stored in the storer so that review.Smart card shown in Figure 1 also comprises operating unit, and this operating unit is at least one in button and the touch-screen.In other embodiments, smart card also comprises fingerprint Identification sensor and controller.Electric paper display can be decline in a glass electric paper display, the electric wetting electric paper display at least one of electrophoresis-type electric paper display, multistable state liquid srystal electric paper display, micro electronmechanical (MEMS) electric paper display, electrophoresis.
Smart card of the present utility model can also comprise power supply and power switch.After power switch was opened, display controller read the information in the integrated circuit (IC) chip, and it is presented on the electric paper display.In one embodiment, power supply is at least one in paper battery, lithium battery, solar cell, nickel-cadmium battery, the nickel iron cell.
In another embodiment, can not have power supply.Smart card can utilize card reader to read and write data by I/O interface and card reader coupling.And the power supply by card reader drive display control circuit in case with the data presentation of read-write on electric paper display.Can pass through wired I/O interface or wireless I/O interface, smart card is embodied as contact intelligent card or contact type intelligent card.
Can realize contact intelligent card with client identification module (SIM) the core of the card sheet.The SIM chip at least the one side be exposed on the smart card in and with the card reader wired connection.Exposure by the SIM card chip is connected external power source, to provide operation required electric energy to described smart card.
In one embodiment, radio-frequency (RF) identification (RFID) chip is wrapped in the smart card and with outside card reader wireless coupling.The RFID chip just can be finished Card Reader with a certain distance from card reader, this is because its card base is embedded with one group of special inductive coil, it finishes read-write operation by radiowave and between the card reader, communication between the two is frequently, for example, 13.56MHZ, this moment, card reader to the process that smart card carries out read-write operation was: at this card when the card reader, the special radio-frequency carrier (comprising control signal) that sends in the card reader forms an alternating magnetic field with certain intensity around the inductive coil of intelligent cards, make the inductive coil in the card base produce electromotive force by this alternating magnetic field just, and utilize the driving power of this electromotive force as the card circuit, and commander's chip is finished reading of data, revise, store etc., give read write line by the radiowave return signal then.
In one embodiment, electric paper display has flexible base, board.In one embodiment, electric paper display is color electric paper display or black and white display.
