Hello, I'm new in RFID and don't know how to make RFID reader read. Can you help me ? How to RFID reader read with freerunning mode from ATMega8's command through serial ?
Note: I use RFID Kanda Starter Kit.

I have done work on RFID Card Reader for that i was using MFRC Chip from NXP. that Chip reads the data from the card according to the command you give.

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.
