Description

The present invention relates to an RFID information medium, and more particularly to an RFID information medium for reading and reading information without contact.

Conventionally, various RFID information media for reading and reading information without contact using RFID (Radio Frequency Identification) technology have a predetermined surface area, for example, a planar medium body, It has a planar antenna located on the back side and an IC chip connected to this antenna and storing predetermined information, and the information can be read and written by an external reader / writer.
Such RFID information media are used as admission tickets and other RFID tags in amusement parks and exhibition halls, RFID labels for specific management of various drugs in hospitals, wristbands for patient identification, etc. .

However, there is a problem that the frequency of reading information greatly varies depending on the distance and tilt angle between the RFID information medium and the reader / writer, that is, the relative position and the relative attitude.
In addition, since the antenna is hidden behind the back side of the medium body, the antenna mounting position is difficult to understand from the front side, and the reading efficiency and reading / writing efficiency of the reader / writer are reduced. is there.
In particular, when the reader / writer is portable, there is a problem that the relative position or relative posture between the reader / writer and the antenna is difficult to be determined depending on the operator.
Even if the reader / writer is fixed, when the RFID information medium held by an unspecified number of personnel is handled and applied to the reader / writer, the relative position or relative position between the reader / writer and the antenna When it is difficult to determine, there is a problem that it is difficult to avoid a decrease in reading efficiency and reading / writing efficiency.

    Moreover, depending on the type of tag, label, wristband, or other RFID information medium, or depending on the display content or form of printing on the front side, the position of the antenna on the back side may also change, When a small antenna is attached to the medium main body, there is a problem that it is difficult to read and write information with various RFID information media, such as confirming the position of the antenna.

Next, an RFID information medium 1 according to a first embodiment of the present invention will be described with reference to FIGS.
1 is a plan view of the RFID information medium 1, FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1, and FIG. However, in FIG. 2, the thickness direction is exaggerated in order to clarify the structure.
The RFID information medium 1 is created, for example, as an amusement park admission ticket, and has a medium body 2 having a predetermined surface area and an RFID inlet 3 (see particularly FIG. 2).

    The medium body 2 is made of any paper material or resin material, for example, in a flat shape, and has a necessary print (for example, “... amusement park, admission ticket”) on its surface side, The RFID inlet 3 is fixedly attached to the back side by gluing or the like.

The RFID inlet 3 includes a protective sheet 4 made of resin, and an antenna 5 and an IC chip 6 accommodated in the protective sheet 4.
The antenna 5 and the IC chip 6 are formed on the resin film 7 that can be accommodated in the protective sheet 4 by various preparation methods.
The antenna 5 is located on the back side of the medium main body 2 and has a planar shape covering a predetermined area, and receives a read / write control radio wave of a predetermined frequency from an external reader / writer 8 (FIG. 4).
A region of a predetermined area where the antenna 5 extends is a rectangular antenna region 9, for example.
The IC chip 6 is connected to the antenna 5 and stores necessary information as an admission ticket, for example.
Therefore, the RFID information medium 1 receives the control radio wave emitted by the external reader / writer 8 from the front surface side by the RFID inlet 3 located on the back surface side thereof, reads information from the IC chip 6 and reads the information to the IC chip 6. Writing is possible.

In particular, as shown in FIG. 1, in the RFID information medium 1 according to the present invention, an antenna position display unit 10 is provided on the surface side of the medium body 2.
This antenna position display unit 10 indicates the position of the antenna 5 located on the back side of the medium body 2, that is, the antenna area 9 where the antenna 5 spreads on the front side, so that the reader / writer 8 can read information at maximum efficiency. This is provided in the position to be.
The antenna position display unit 10 can be a perforation region having a rectangular shape, for example, having a contour line so as to substantially overlap the antenna region 9.
Here, “substantially overlap” means that the antenna position display unit 10 has substantially the same area and shape as the antenna region 9 on the front and back surfaces of the medium body 2 and is in an almost overlapping state, as a matter of course. It is assumed that the state where the part 10 is included inside the antenna region 9 or, conversely, the antenna region 9 is included inside the antenna position display unit 10 is also included.
Note that an auxiliary instruction for operation such as “Please put a reader / writer on the inside of this perforation” can be printed in advance on the antenna position display unit 10 as necessary.

An operation of reading information on the RFID information medium 1 (IC chip 6) by the reader / writer 8 in the RFID information medium 1 having such a configuration will be described with reference to FIG.
FIG. 4 is a perspective view for explaining an operation of reading information on the RFID information medium 1 by the reader / writer 8. The operator of the reader / writer 8 looks at the antenna position display unit 10 that appears on the surface side of the RFID information medium 1. The reader / writer 8 is aligned with the portion of the antenna position display unit 10 so as to be parallel to each other as much as possible.
Since the antenna region 9, that is, the antenna 5 is located on the back side of the antenna position display unit 10, the reader / writer 8 can be assigned to the position where the reading of information is maximized, and the reading efficiency of information and further writing Efficiency can be maintained at a predetermined level.
Therefore, particularly when the reader / writer 8 is portable, the operator accurately recognizes the position of the antenna 5 hidden behind the RFID information medium 1 by the antenna position display unit 10 (perforation region), and Can be reliably read or written.

    In the present invention, instead of the perforated antenna position display unit 10, the outline that substantially overlaps the antenna region 9 in which the antenna 5 extends is shallowly cut (that is, the antenna position display unit 10 is not separated from the medium body 2). It is also possible to make a cut area from a shallow cut.
