Description

  The present invention relates to a contactless IC card system in which a short-range wireless communication function is incorporated in a mobile terminal device.

  In recent years, as one of the short-range wireless communication, there is a case of contactless IC card (contactless IC tag, contactless IC, wireless IC tag, contactless data carrier, RFID, etc. In the claims, the term “non-contact IC card” is applied in various fields.

  One example is a non-contact IC card in which a non-contact IC card in which data of a printed home page address (URL) is written is pasted on a paper medium of a publication in a publication that introduces a company home page. Some readers read address (URL) data by holding a reader or a portable terminal with a built-in reader function over a predetermined part of a publication (for example, see Patent Document 1).

  Another is application to an entrance / exit management device that manages entrance / exit of a room. In some cases, a non-contact IC card reader is provided at the entrance of a room, and a non-contact IC card is held over the door to unlock, lock, and set to a warning mode (for example, Patent Document 2). reference.).

  However, in the above system, even if a function for supporting a non-contact IC card system is incorporated in the mobile terminal, it is troublesome to input a simple homepage address, etc., and it is easy to read data that is easy to input erroneously or to become a communication partner. It was applied only to simple uses such as mode switching operation on the device side. In addition, there has been no system utilizing the ergonomic and easy-to-understand operability of “holding” a non-contact IC card itself or a portable terminal corresponding to the system. Therefore, in a system in which a function for supporting a non-contact IC card system is incorporated in a portable terminal, an operation when tackling data necessary for the portable terminal is complicated.

  Further, even if the mobile terminal is expensive and a function for supporting a non-contact IC card system is incorporated, the convenience of the user cannot be dramatically improved. Furthermore, for this reason, the spread of these systems has been hindered, and as a result, the cost of the entire system has been expensive.

  An object of the present invention is to provide a technique for improving operability during non-contact communication in a communication device that performs non-contact communication, and to improve user convenience.

  The present invention is characterized in that the number of non-contact communication with another communication device within a predetermined time is confirmed, and data for non-contact communication is changed according to the confirmed number of times.

  When the mobile phone 101 is held over the non-contact IC card 104 attached in the vicinity of the printing location of the photo 103 (S501), the entire non-contact IC card 215 generates power by the power generation circuit 219 and enters an operating state. (S502). The control unit 216 of the non-contact IC card 215 transmits a signal notifying that it is in an operating state via the modem circuit 218 (S503). Upon receiving this signal, the control unit 203 of the non-contact IC card reader / writer unit 202 transmits time information and an authentication ID from the control unit 203 via the modulation / demodulation circuit 205 (S504). Here, the time information is obtained from a clock unit in the mobile phone main unit 208 (not shown).

  In order to check whether the received authentication ID is valid, the control unit 216 of the non-contact IC card 215 performs authentication processing by comparing with the authentication ID stored in the nonvolatile memory 217 (S505). If there is no problem with the authentication (S506), the control unit 216 stores the received time information and authentication ID in the terminal holding count management table in the nonvolatile memory 217 (S507).

  Next, the control unit 216 transmits the authentication ID to the non-contact IC card reader / writer 202 side (S508).

  Similarly, the control unit 203 on the contactless IC card reader / writer 202 side is stored in a non-volatile memory (not shown) in the mobile phone main unit 208 in order to check whether the received authentication ID is valid. Authentication processing is performed by collating with the authentication ID (S509). At this time, a non-volatile memory may be separately provided in the non-contact IC card reader / writer 202 for processing. If there is no problem with the authentication (S510), the control unit 203 transmits a data request signal to the non-contact IC card 215 (S511). When the non-contact IC card 215 receives this data request signal, the control unit 216 refers to the terminal holding count management table in the nonvolatile memory 217 (S512), and the same authentication ID as the latest authentication ID stored earlier is obtained. It is searched whether there is any (S513). If the same authentication ID does not exist, the thumbnail data stored in a predetermined area of the nonvolatile memory 217 is read and transmitted to the non-contact IC card reader / writer 202 (S514).

  If there is the same authentication ID, the number of receptions in a predetermined time, that is, the number of times the mobile phone 101 is held over the predetermined time is calculated from the time information of both (S515). In this case, if the time held in the past is calculated to be equal to or longer than the predetermined time (S516), the thumbnail data stored in the predetermined area of the non-volatile memory 217 is read and the non-contact IC card reader / writer is read. It transmits to 202 (S514).

  If it is calculated that the time held in the past is within the predetermined time, the original data stored in the predetermined area of the nonvolatile memory 217 is read and transmitted to the non-contact IC card reader / writer 202 (S517). ).

  In this way, by switching the data to be transmitted according to the number of times the cellular phone 101 is held over a predetermined time and transmitting it to the non-contact IC card reader / writer 202, data necessary for the cellular phone 101 can be obtained by a simple operation. Can work on.

  In addition, in order to improve a more friendly operability, the operator may be notified by the display unit 214, the speaker 212, or the like when mutual authentication confirmation is completed or when data reception is completed.

  In the first embodiment, a photo book is taken as an example, but a non-contact IC card may be attached to a single photo or poster instead of a book form such as a publication.

  A non-contact IC card may store data of a plurality of image sizes.
