Hi,

I have a lot of applications done with RFID. See my web http://www.picshop.nl/rfid.html
Here connected to a AmiPIC18 board with the PIC18F25K20. The firmware is in PICBASIC Pro.

After reading a Tag, the reader give a Hex02. So, you have to wait for that character and store the next 10-byte in a string. Thats the Tag ID. If the first byte = 0, than you have a read only tag. (1 means read/write)
The OEM reader what I use, has a CP signal, this will be high after reading a Tag, then 210ms later, the reader wil send out (9600 baud) the TAG ID. I use in the firmware the CP signal to poll of a Tag is reading or not. The micro is run on 8 Mhz or faster to read 9600baud.

I will post tomorrow some firmware to show hows iets work if you want.

Regards,
