Description

  The present invention relates to a technique for improving a flexible sheet in which an RFID tag is embedded.

Conventionally, as a technology that can record visual information such as characters and figures and digital data as one body, RFID tags are embedded in printing paper, and it is used for reader / writers for printing and printing paper in copiers with printer and facsimile functions. By providing a reader / writer, visual information is printed on printing paper based on character data or graphic data transmitted from an external device such as a personal computer, and data to be recorded as digital data is written in an RFID tag. Technology is known. (For example, refer to Patent Document 1.)

By the way, in the case of admission management with a vehicle permit in which the RFID tag is embedded as described above, for example, in order to convey information such as instructing the destination to the driver or instructing the visit time, a memo is given to the driver. When it is necessary to hand over the vehicle, it is inconvenient because the vehicle window has to be opened or the driver has to get off the vehicle.
In addition, it is not limited to vehicle operation management. Generally, it is convenient if the destination, visit time, and other necessary information can be displayed in a visible state on a permit permitting outsiders to enter. It was.

  Therefore, an object of the present invention is to enable various data of an IC tag to be displayed in a visible manner on an RFID sheet in which a readable / writable IC tag or the like is embedded.

  To achieve the above object, the present invention provides a flexible RFID sheet in which identification information and the like are recorded and read / write by non-contact wireless communication and a communication antenna is embedded. The display unit on which at least a part of the information written in is visibly displayed is formed integrally.

As described above, when the display unit is integrally formed on the RFID sheet in which the IC tag in which the identification information or the like is recorded is embedded, for example, when applied to a permit permitting entry of the vehicle, the driver Is convenient because there is no need to get out of the vehicle or open windows.
Here, by making the RFID sheet a flexible sheet, it is easy to handle, is not easily restricted by the place of placement, and can be manufactured at low cost. As such a flexible sheet, for example, a resin film or paper can be applied.
In addition, as a display portion that maintains flexibility, for example, an organic EL in which a light-emitting organic layer is sandwiched between a pair of electrodes, or an arbitrary display device such as a cholesteric liquid crystal material can be applied.

In the present invention, the RFID sheet is a printable paper.
By using paper that can be printed in this way, various types of information other than information recorded on the IC tag can be printed, which is more convenient.

By forming a display unit that displays at least part of the information written on the IC tag so as to be visible on a flexible RFID sheet in which an IC tag or the like on which identification information is recorded is embedded, This is convenient because necessary information can be displayed in a visually recognizable manner.
Further, by making the RFID sheet a printable paper, a more diverse information transmission medium can be obtained.

Embodiments of the present invention will be described with reference to the accompanying drawings.
Here, FIG. 1 is an explanatory view showing an example when the RFID sheet according to the present invention is applied to a vehicle entrance / exit management system, and FIG. 2 is an explanatory view explaining an example of the RFID sheet.

  The RFID sheet according to the present invention is configured such that various data written on the IC tag can be visually displayed on a flexible RFID sheet in which an IC tag or the like is embedded. The case where it is applied to a permit will be described as a representative example.

  A permit issued by a company or the like is granted to those permitted to enter or leave the company or the like. This permit is an IC tag in which identification information serving as an ID tag and an antenna for communication are embedded. In this embodiment, for example, two printable sheets having a size of about A4 or A5 are used. By sandwiching and integrating the IC tag and the antenna with paper, a form that can be bent with a thickness of about 0.1 to 0.5 mm is obtained.

  Such a permit is placed, for example, on the dashboard of the vehicle, and when an approach of the vehicle is detected, a radio wave is transmitted from the transmission antenna 11 via a controller (not shown) as shown in FIG. Then, the IC tag is electrically activated by the radio wave, the radio wave accompanied by the ID information sent from the IC tag is received by the receiving antenna 12, and collated with the ID information registered in advance by the controller, and the collation is confirmed. In such a case, the gate 13 is opened to allow passage.

  As shown in FIG. 2, the RFID sheet 1 has a display circuit 4 embedded between two sheets of paper in addition to an IC tag 2 and a communication antenna 3 on which identification information is recorded. Data such as character data and graphic data can be displayed on the display unit 5 by the circuit 4 so as to be visible.

The display device of the display unit 5 is, for example, an organic EL device having a structure in which a light-emitting organic layer is sandwiched between two electrodes, or a cholesteric liquid crystal material that can maintain display without applying power once it is displayed on the screen. In any case, display is controlled by the display circuit 4.
The display power may be power generated in the circuit of the IC tag 2 by radio waves transmitted from the controller side (not shown) through the transmission antenna 11, but a separate display power supply is provided integrally. You may do it.

The operation of the RFID sheet 1 as described above will be described.
When a company or the like that permits the operation of the vehicle issues a permit (RFID sheet), the driver places the RFID sheet 1 on the dashboard or the like of the vehicle. At this time, since it is a flexible paper, it can be easily handled, and since it can be bent to some extent, it is difficult to be restricted in the place where it is placed, and it can be produced at low cost. Then, when approaching the visiting company's gate, a command is issued from a controller (not shown) that senses the approach, and a radio signal is emitted from the transmitting antenna 11.

  When the communication antenna 3 of the RFID sheet 1 receives the radio wave, the IC tag 2 is activated and transmits the radio wave with ID information from the communication antenna 3. When the reception antenna 12 receives this radio wave, the controller collates the ID information. When the confirmation is confirmed, the gate 13 is opened and the destination, time, and other necessary data are transmitted wirelessly from the transmission antenna 11 through the controller.

  Then, those data are written into the IC tag 2 through the communication antenna 3, and necessary data are displayed on the display unit 5 through the display circuit 4 so as to be visible. For this reason, the driver or the like can enter the hall as it is and move to a necessary location based on the data displayed on the display unit 5.

The same goes for when leaving, but by providing the display portion 5 that can be visually confirmed on the RFID sheet 1 as described above, entry / exit can be smoothed even when security is maintained.
In addition, since the RFID sheet 1 can be printed, information such as other common items can be printed in advance, which is convenient.

  In the above embodiment, the case of an RFID sheet in vehicle operation management has been described as an example. However, the present invention can also be applied to other pedestrian visitors and on-site management according to the security level in the hall. It is.

  In addition, this invention is not limited to the above embodiment. What has substantially the same configuration as the matters described in the claims of the present invention and exhibits the same operational effects belongs to the technical scope of the present invention. For example, the arrangement of the IC tag 2, the communication antenna 3, and the display circuit 5 is an example, and the type of the display device of the display unit 5 is arbitrary.

  Since the display portion is integrally provided on the RFID sheet, it is convenient to apply it to, for example, a permit for entering / exiting a company or the like, or entering a restricted access area.
