The label attaching portion 14 is shown to include a label 40 is attached to the amount of money and various propaganda or pattern is formed.

According to the configuration as described above, when the radio recognition chip 110 embedded in the body 10 of the casino chip 100 is eccentrically positioned to one side, when stacking a predetermined amount of casino chips 100 of about 20 pieces. 6, the antenna 112 of the radio recognition chip 110, which is eccentrically positioned in the body 10, is partially overlapped and another is positioned at different positions.

As a result, there is no collision between the frequencies emitted from the antennas, and the communication with the reader is performed smoothly so that not only the exact quantity can be recognized, but also the condition for easily recognizing the exact total amount of the casino chips. .

Therefore, regardless of the number of the fixed amount, which is about 20 at the time of use or storage of casino chips, it is possible to grasp the exact amount as well as the total amount smoothly.

The label attaching portion 14 is to be partitioned by the protruding frame 14a protruding from the upper and lower surfaces of the body during molding, so as to cover the outer periphery of the body as well as the conditions that can be attached to the correct position when the label It will also have a role of partitioning the molded part and the label attachment portion molded to be. At this time, the height of the protruding frame is formed at the same height as the molded part.

According to the results obtained under the same conditions, when the wireless recognition chip in the casino chips is located at the center of the center, it can be seen that at least 1 to 4 and no more are recognized.

In addition, when the outer diameter of the radio recognition chip is larger than 1/2, even if it is located eccentrically to one side, as the part of the antenna portion overlaps, it can be seen that interference occurs and the recognition rate decreases.

On the other hand, when the outer diameter of the radio recognition chip is even smaller than 1/2, it can also be seen that the recognition rate is lowered due to insufficient induction of power for communicating with the antenna of the reader.

Accordingly, when the outer diameter of the wireless recognition chip is within the range of 1/2, it will have a condition that can be easily recognized up to about 20.

Therefore, it is preferable that the radio recognition chip to be applied to the present invention be formed within 1/2 of the outer diameter of the casino chips.

As described above, the present invention, by eccentrically positioning the radio recognition chip embedded in the body of the casino chips to one side, minimizing the collision between the frequencies emitted from the antenna of the radio recognition chip even when stacking a certain amount of about 20 As a result, not only the exact quantity but also the total amount of the casino chips can be accurately understood.

In addition, the protrusion formed on the outer periphery of the casino chips can be easily formed into a shape that requires a shape, as well as having an effect that can be appropriately manufactured according to the characteristics of the company.

In addition, by forming an insertion groove and a hole in the insertion plate on which the radio recognition chip is mounted, so that the thickness of the radio recognition chip embedded therein can be compensated, so that the thickness of the casino chips can also be manufactured in accordance with the standard.
