Currently, notebook computer import / export automation technology can be divided into technology that automatically recognizes notebook computer information in real time and manages notebook computer import / export based on a database through a network. In the case of notebook recognition, conventionally, the bar code technology is mainly used.

The barcode technology uses a method of automatically recognizing a geometric bar line printed with ink on paper by using a one-dimensional infrared image sensor, and attaches a barcode sticker on which the notebook information is printed on the notebook in advance and recognizes the barcode by recognizing the barcode. The notebook computer import / export management is performed by interworking the recognized notebook computer information with a database.

Since the barcode is optical, the infrared sensor should be approached within a few tens of centimeters near the sticker on which the barcode is printed to recognize the barcode. Therefore, the barcode of the notebook in the bag has a disadvantage that it does not recognize. In order to recognize a notebook computer by barcode method, it is necessary to open the notebook bag, take out the notebook and bring a barcode reader to the notebook. This can be cumbersome for both entrants and security personnel.

The present invention has been made to solve the above problems, and the technical problem to be achieved by the present invention is to facilitate the attachment of the surface of the notebook computer for the notebook computer import and export management, the existing sponge or Schiropol An RFID tag having a thin spacer, which is thinner than a spacer, is provided.
