Description

Card with radio RF identification label
Technical field
The invention relates to a kind of card with radio RF identification label, particularly a kind of can display message and the card of hardware switch with control radio RF identification label function arranged.
Background technology
Radio frequency identification (Radio Frequency Identification, RFID) be a kind of chip of built-in radiotelegraphy, also can note down a series of information in the chip, as product category, position, date etc., maximum benefit is to improve Item Management efficient, and Item Information is recorded on the bar code more at present, obtains information and scan bar code with scanner again, and RFID only needs induction within the specific limits, and can once read bulk information.The RFID technology can be applicable to gate inhibition's control, associating ticket, communications and transportation etc.
Rfid system mainly comprises label (Tag), reader (Reader) and main frame in forming.Label is the storage assembly for storing of data, reader then is from the label reading of data or with the instrument of deposit data in the label, reader is sent to data streams read in the computer system, uses different application programs to come unscrambling data, reaches correct decision-making rapidly to assist the user.Label can be divided into active (Active) and two kinds of passive types (Passive), and active tag includes battery, and transmission information is at any time given reader, and long communication distance is arranged, and can store bigger internal memory, but price is higher; The passive label power supply produces the little electric current of induction from electric wave that reader sends to label and supplies its power supply power, utilizes electric wave to pass its information back reader again, so communication distance is shorter.The passive label benefit do not need to be external battery, can reach that volume is little, low price, the life-span is long and advantage such as numerical data portability.The antenna of passive label is built-in, in order to induction and generation radiowave, with transceive data.
Because have the card of RFID label function at present, be to rely on the alternating magnetic field that reader produced to start the interior RFID label function of card, on card, do not have the gauge tap whether special design allows RFID label function in the card whether start, therefore have products such as the stored value card of RFID label function or gate inhibition at present, there is the card-reading system that meets this RFID label can in communication distance, read data and information in the card as long as anyone holds, therefore on safety, has doubt.When carrying out data transmission with RFID at present, the information that can not show data contact in the card on the card of this RFID label function, the holder can't be known and control receive and the information content of transmitting from the RFID tag card of holding, the stored value card that for example has the RFID label function, when concluding the business, and can't learn the amount of money of present exchange deduction and the remaining sum in the card, the user can't effectively control the information in the stored value card.
Summary of the invention
In view of above problem, the invention provides a kind of radio frequency identification (Radio FrequencyIdentification that has, RFID) card of label, in order to avoiding being read data in this label with the RFID reader that meets, and can make the holder of this electronic installation know that this RFID label is received from the information of RFID reader or the information that RFID sends the RFID reader to by other people.
A kind of card of the present invention with radio RF identification label, in order to receive first electric wave signal that the radio frequency identification reader is sent with first information, and behind this first electric wave signal of response, passback has second electric wave signal of second information and gives this radio frequency identification reader, and this card includes: coil, little process chip and switch.Coil is arranged in the card, and this coil has first marking current of the first information in order to respond to first electric wave signal with formation.Little process chip is arranged in the card and electrically connects coil, this little process chip is in order to resolve first marking current that coil transmitted, produce secondary signal electric current according to this and give coil, give the radio frequency identification reader according to the secondary signal electric current to form second electric wave signal and to return second electric wave signal by coil with second information.Switch is arranged between coil and the little process chip, and this switch is in order to the electric connection between control coil and little process chip.
Another kind of the present invention has the card of radio RF identification label, in order to receive first electric wave signal that the radio frequency identification reader is sent with first information, and behind this first electric wave signal of response, passback has second electric wave signal of second information and gives this radio frequency identification reader, and this card includes: coil, little process chip and Electronic Paper.Coil is arranged in the card, and this coil has first marking current of the first information in order to receive first electric wave signal with formation.Little process chip is arranged in the card and electrically connects coil, this little process chip is in order to resolve first marking current that coil transmitted, produce secondary signal electric current according to this and give coil, the secondary signal current resonance is formed second electric wave signal and return second electric wave signal by coil and give the radio frequency identification reader with second information.Electronic Paper is arranged at card, and Electronic Paper electrically connects little process chip, this Electronic Paper by little process chip control to show the first information or second information.
The present invention controls radio RF identification label by switch and whether starts, and by the information that display show to transmit or receives, and it is thief-proof and can effectively control the information that contact transmits to reach data.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
