I remember information.

  Furthermore, since the non-contact medium processing machine 30 records which parent medium 10 is used for processing when the child medium 20 is processed, the identification information of the parent medium 10 is displayed when the child medium 20 is processed. In addition to writing to the child medium 20, log information such as an entry / exit history written to the child medium 20 and processing contents are stored in the storage unit 33.

  Here, various processing functions executed by the control unit 32 of the non-contact medium processing machine 30 using the parent medium 10 and the child medium 20 will be specifically described. The processing functions described below can be used in appropriate combinations according to the application and usage environment of the system.

(Basic processing)
The non-contact medium processor 30 has a function of detecting all of these media when the parent medium 10 and the child medium 20 are close to each other in the communication area, and the detected parent medium 10 is a predetermined parent. When it is a medium, that is, when it is determined that the medium can be processed by the non-contact medium processor 30, information acquired from the parent medium 10 by non-contact communication (described in a predetermined memory area or file of the storage means 33) Information) is performed on the child medium 20.

(Program execution processing)
When the information described in a predetermined memory area or file of the parent medium 10 is a program code, the non-contact medium processor 30 is close to the parent medium 10 and the child medium 20 in the communication area. In doing so, a program based on the program code acquired from the parent medium 10 by non-contact communication is executed to perform processing on the child medium 20.

(Card issue processing)
The non-contact medium processor 30 is configured such that when the parent medium 10 describes information or a program for issuing the child medium 20 as a key card, the parent medium 10 and the child medium 20 are close to each other in the communication area. When present, a process of issuing the child medium 20 as a key card is performed based on information or a program acquired from the parent medium 10 by non-contact communication.

(Card issue restriction processing)
When the issuance restriction information of the child medium 20 is described in the parent medium 10, the non-contact medium processor 30 determines whether the parent medium 10 and the child medium 20 are close to each other in the communication area at the same time. The issuance restriction information of the child medium 20 stored in the medium 10 is read by non-contact communication, and processing for restricting the number of issuance of the child medium 20 and the types that can be issued is performed based on the read issuance restriction information.

(Data writing process)
The non-contact medium processing device 30 includes data for child media to be stored in the child medium 20 when the parent medium 10 and the child medium 20 are close to each other in the communication area, and the child medium 20 has a child medium. A processing program for writing data for use is read from the parent medium 10 by non-contact communication, and necessary child medium data is written to the child medium 20 based on the read medium processing information. In addition, when the card is issued, the non-contact medium processing device 30 transmits part or all of the information of the parent medium 10 or information generated from these information to the issued key card (child medium 20) by non-contact communication. Perform the writing process.

(Data reading process)
Information such as firmware codes to be stored in the non-contact medium processor 30 is divided in advance and stored in a plurality of child media 20. The non-contact medium processing machine 30 reads the medium processing information read from the parent medium 10 by non-contact communication when the parent medium 10 and the plurality of child media 20 storing the above codes are present close to each other in the communication area. Based on the above, the code stored in each child medium 20 is sequentially read by non-contact communication, and the read firmware code is sequentially written in a predetermined memory area of the storage means 33.

(Continuous data collection process)
The non-contact medium processing machine 30 reads the medium processing information stored in the parent medium 10 by non-contact communication when the parent medium 10 and the child medium 20 are close to each other in the communication area at the same time. Based on the medium processing information, the management information (for example, log information of the entry / exit history etc.) stored in its own storage means 33 is sequentially written into the parent medium 10 or the child medium 20. If the management information has a large data capacity, a process of dividing the management information into a predetermined capacity and writing it to the plurality of child media 20 is performed.

  In the non-contact medium processing system 1 configured as described above, when one parent medium 10 and a plurality of child media 20 are brought close to the communication area of the non-contact medium processing machine 30 and exist simultaneously, The medium processing information (for example, issue restriction information for limiting the number of issued sheets, various processing contents) is read from the parent medium 10 by non-contact communication, and processing for rewriting the contents of the child medium 20 is executed based on the contents of the read information ( Card issue). At this time, since the non-contact medium processing machine 30 reads the issue restriction information from one parent medium 10, the writing process is executed only for the child media 20 corresponding to the number of pieces corresponding to the issue restriction information. The

  By the way, the processing described above is executed by the non-contact medium processing machine 30 (control means 32). For example, the card-type electric lock provided at each door of the guest room in the hotel card lock system is used as the non-contact medium processing machine 30. It is possible to have the function of.

  In this case, the parent medium 10 is switched from the normal operation mode (the mode for locking and unlocking the lock using the key card) to the card issuing mode (the mode for issuing the child medium 20 as the key card). A processing program for issuing a card is described.

  When the parent medium 10 in which the processing program is described is present in the communication area in close proximity to the communication area, the card-type electric lock can be removed from the normal operation mode by the processing program acquired from the parent medium 10. The mode is switched to the issue mode, information on the child medium 20 is read, the type of the child medium 20 is determined from the read information, and a key card is issued according to the type of the child medium 20.

  Specifically, when information necessary for unlocking and unlocking the lock of the card type electric lock (for example, identification information such as an employee code in the employee card) is stored in the child medium 20 in advance, the child medium 20 Is stored in the storage means 33, and thereafter, the child medium 20 is validated as a key card (key).

  On the other hand, when the information necessary for locking / unlocking the lock of the card type electric lock is not stored in the child medium 20 (when the child medium 20 is a raw card), a new ID (for example, a random number) is used. (Identification information) is generated and the ID is written in the child medium 20, and thereafter the child medium 20 is validated as a key card (key).

  Thus, when the card-type electric lock has the processing function of the non-contact medium processing machine 30, the validity of the locking / unlocking information read from the key card (child medium 20) owned by the guest is determined. In addition to the lock / unlock control function as a normal card-type electric lock that locks and unlocks the lock, it also has the function of the non-contact medium processing machine 30 described above. The card can be issued with a simplified system configuration.

  And since the function of the non-contact medium processing machine 30 is provided in the card-type electric lock, even if the guest loses the key card (child medium 20), there is no need to go to the front desk for reissuance. An employee's master card (parent medium 10) and another key card (child medium 20) are simultaneously placed close to each other in the communication area of the card-type electric lock, so that a new key card (child medium 20) can be obtained. It can be issued easily.

  When a new key card is issued by the child medium 20, the identification information of the newly issued key card (child medium 20) is stored in the card-type electric lock, so that the lost key card (child medium 20) is stored. Even if it is used, it cannot be used because the identification information is different.

  As described above, the non-contact medium processing system 1 includes the parent medium 10 that stores issuance restriction information for restricting the issuance of the child medium 20 and medium processing information such as child medium data in the child medium 20, and the parent medium 10. The non-contact medium processing machine 30 is simultaneously present in the communication area of the non-contact medium processing machine 30, and the non-contact medium processing machine 30 reads information stored in each medium by non-contact communication. Then, the non-contact medium processing machine 30 issues the child medium 20 by limiting the types and the number of issues that can be issued based on the medium processing information read from the parent medium 10 by non-contact communication. This provides a highly reliable non-contact medium processing system 1 that can prevent inadvertently issuing an unauthorized child medium 20 or illegally issuing the child medium 20 and ensure sufficient security. be able to.

  Further, the non-contact medium processor 30 is configured such that when the information described in a predetermined memory area or file of the parent medium 10 is a program code and the parent medium 10 and the child medium 20 exist simultaneously in the communication area, An interpreter function that executes a program acquired from the medium 10 by non-contact communication and performs processing on the child medium 20 can be realized.

  Further, when the card-type electric lock has the function of the non-contact medium processor 30, if information or a program for issuing the child medium 20 is described in the parent medium 10 to be detected, the parent medium 10 and the child medium When the medium 20 is simultaneously present in the communication area, the child medium 20 can be issued as a key card. This makes it possible to issue a key card with only a card-type electric lock, eliminating the need for an issuing machine. For example, if the parent medium 10 and the child medium 20 held by the landlord of the rental house are simultaneously held over a card-type electric lock, the child medium 20 is issued as a new key card.

  Also, if the authority for each type of medium that can be issued is set in the parent medium 10 and the type of medium that can be issued is limited by the authority, the key card (child medium 20) that can be issued for each master card (parent medium 10) Can be restricted (authorization function).

  Furthermore, a part or all of the information of the parent medium 10 or information generated from these information can be written to the issued key card (child medium 20). For example, when a master card (parent medium 10) has a basic ID, information indicating which master card (parent medium 10) is simultaneously held when a key card (child medium 20) is issued is added to the basic ID as a serial number or If a branch number is assigned and written in the key card (child medium 20), the key card (child medium 20) can be managed by data having a basic ID and meaning.

  Also, when the firmware code of the non-contact medium processor 30 is divided and recorded for a plurality of child media 20, and the parent medium 10 and the plurality of child media 20 are simultaneously present in the communication area. The codes can be sequentially read from the plurality of child media 20 by non-contact communication, and the read codes can be written in a predetermined memory area of the non-contact medium processor 30. As a result, if the information cannot be stored in one parent medium 10, the subsequent information (data or program) is divided and recorded in a plurality of child media 20, and the parent medium 10 and the plurality of child media 20 are not recorded. Information acquired by contact communication can be written in a predetermined memory area of the non-contact medium processor 30.

  Further, when the parent medium 10 and the plurality of child media 20 exist in the communication area at the same time, information on the memory area of the storage means 33 of the non-contact medium processing machine 30 (for example, when used in a hotel card lock system, Log information of the entry / exit history), and the read information can be sequentially written in the child medium 20 by non-contact communication. At that time, even if the amount of information in the storage means 33 is large, it can be divided into a plurality of child media 20 and processed simultaneously. Thereby, the information of the non-contact medium processing machine 30 can be taken out using the parent medium 10 and the plurality of child media 20 and collected as continuous data.
