Interactive method and system for recording and playing data

An interactive system for recording and playing data, the system comprising:

• an RFID reader for RFID tag reading;
• a recording and playing unit for recording data so as to generate recorded data, and for playing the recorded data;
• a memory for storing the recorded data;
• and
• a processing unit coupled electrically to the RFID reader, the recording and playing unit, and the memory, the processing unit executing the steps of
• a) receiving a request signal that is one of a record/stop request signal and a play/stop request signal,
• b) after step a), determining whether to activate the RFID reader in response to receipt of the request signal,
• c) activating the RFID reader when it is determined to activate the RFID reader in step b),
• d) after step c), receiving an identification code corresponding to an RFID tag read by the RFID reader, and
• e) after step d), controlling the recording and playing unit to record data, to generate the recorded data which corresponds to the identification code, and to store the recorded data in the memory using the identification code as an index when the request signal is the record/stop request signal and the record/stop request signal is again received by the processing unit when the recording and playing unit is recording data, and controlling the recording and playing unit to search for the recorded data which corresponds to the identification code in the memory and to play the recorded data corresponding to the identification code after finding the recorded data corresponding to the identification code when the request signal is the play/stop request signal.
