At present the file pouch that uses need on bag, print or adhesive label marking, of long duration the handwriting is blurred or fade and be beyond recognition, and archive content can not be accomplished tight secret; This class file is fixed together usually, can not take out use separately, and is more numerous and diverse in the arrangement of the archive of the big unit different size of portfolio, different model, neither portable band and losing easily, and the progress of work is slow, is unfavorable for lending, file and searching of file.
Summary of the invention
The purpose of this utility model is, a kind of e-portfolio is provided, and it is big to make it have memory capacity, can divide by the specification detail and classify, and intellectuality, safe and reliable, can not arbitrarily forge modification, volume is light and handy, is beneficial to carry and keeping.
The utility model provides following technical scheme to achieve these goals: electronic tag is installed on the bag, radio frequency read-write equipment, chip and antenna are installed in the electronic tag.Described bag is provided with and the bonding strip of bag along sealing.
Electronic tag described in the utility model also claims radio-frequency card, and it has intelligent read and encrypted communication function, and it has unique id number, simultaneously can enroll several data information, these information can be carried out Classification Management according to needs, also can forever preserve, and performance is high and safe and reliable.Electronic tag described in the utility model is being commonly called as of RFID, and its principle is to give receiver by the radio wave energy of scanner transmitted frequency, in order to drive acceptor circuit the code of inside is sent, and this moment, scanner just received this code.Receiver special be to exempt from battery, exempt from contact, exempt to swipe the card thus be not afraid of dirty, and the wafer password to be that the world is unique can't duplicate safe, the long-life.Electronic label technology is made up of chip and antenna, and thickness is 0.01 centimeter, has independently 2 64 power ISNs, the chip IS015693 that adopts international standards.
Owing to adopt technique scheme, the e-portfolio that the utility model provides, have the following advantages: owing to adopt contactless hand inspection, avoid the error checked, information extraction is accurately convenient, be easy to carry about with one, be convenient to computer input and storage and preserve, have the ability of intelligent read and coded communication, and memory space is big, can discern a plurality of Material evidence bag interior labels simultaneously at a high speed, increase work efficiency.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details, electronic tag 2 is installed on the bag 1, radio frequency read-write equipment, chip and antenna are installed in the electronic tag 2.Described bag 1 is provided with and the bonding strip 4 of bag along 3 sealings.When using e-portfolio of the present utility model, put into the radio system zone, by scanner information is sent to receiver, in order to drive acceptor circuit the code of inside is reached computer, computer can be discerned simultaneously a plurality of e-portfolio information rapidly, the managing detailed catalogue in the display file bag, lends and date of repayment etc.The utility model not detailed description is known technology.
