  What kind of command ? How is the format ?Can you give me example from C Language or other, please..
  Thank you for your help.

  I have done with RFID Reader and PIC. I think it's easy, just read UART. See example c code #-Link-Snipped-#.

  I think your RFID reader can read automatically, but in my RFID can't read like that. Maybe need kind of command from Microcontroller, isn't it ?
  or maybe there are other solutions ? Can you explain your RFID reader how your RFID can read ?
  thank you for your answer.. -senyum-

  I see the RFID Kanda datasheet, not found any data protocol that need to send. Need to test the demo program provided. I never heard any protocol related to RFID like AT Command for GSM.
  
  My RFID I use is straight forward. Microcontroller not need to send anything, when I touch RFID tag, the RFID reader will send RS232 Packet. [0x01 10byte-unique-number 0x02]. I just read the 10byte array.
