[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a plurality of different information (bank account number, airplane, etc.) on an IC chip in a non-contact RFID label that receives power from a dedicated reader / writer device using electromagnetic induction. A flight number, a passport number, a copy of an identification card, etc.) are recorded with several levels of security ranking (assignment of importance), and an LED and an approval button are provided on the RFID label. With this configuration, when information is read out by the dedicated reader device, the LED emits light in conjunction with the security rank of the information to be accessed. Therefore, the user can check which information in the IC chip the dedicated reader device is trying to access, and if the user does not press the approval button, the information to be accessed is not disclosed. For this reason, a high security environment was realized.
[0011]
The present invention also provides a common format (BMP image, XML, etc.) for information such as a copy of the passport, contact information of the local embassy, user's suitcase shape / photo, etc., in an RFID label that is always portable by the user. It is recorded with. For this reason, when trouble occurs at the travel destination, the information in the RFID label is read out by the reader device, so that it does not depend on the traveler's language skills and in the case of a suitcase transport error or loss of ID Enables quick troubleshooting.
[0012]
Furthermore, in the present invention, a user records travel information such as a country name, a travel destination, and a flight name to be used in advance in an IC chip of an RFID label with an approval function. RFID label readers installed at stations and airfields automatically access and read information on travel information in the IC chip when the RFID label approaches, and provide guidance on the display device according to the destination and flight name. indicate.
