Claim:
1. A communication apparatus comprising: a data generating unit for generating write data to be sent to another communication apparatus at an arbitrary timing; a communication unit for repeatedly sending a read request to the other communication apparatus until the write data is generated and, at the same time, for repeatedly receiving a read response sent from the other communication apparatus in response to the read request; and a data acquisition unit for acquiring read data, which is sent along with the read response by the other communication apparatus, when the read data is generated at an arbitrary timing by the other communication apparatus, in which only after the read data has been fully generated and after receipt of a respective read request after the read data has been fully generated, the other communication apparatus sends the read data for acquisition by the data acquisition unit of the communication apparatus, such that the other communication apparatus sends the fully generated read data to the communication apparatus without having to issue a notification communication to the communication apparatus indicating that the read data has been fully generated prior to sending the fully generated read data thereto, and in which communication between the communication apparatus and the other communication apparatus, including all of the sending of the read request by the communication unit, all of the sending and receiving of the read response, and all of the sending and receiving of the read data, is by way of a single type of communication technology with a single type of protocol which is passive communication in compliance with a near field communication (NFC) protocol for communication apparatuses spaced within approximately several tens of centimeters of each other.
