Hello,

I would like to know is it possible to assign an id number to an xbee and use them as rfid chips. So every chip would be a coordinator and each "reader" would be an end point. Once an end point comes into range it receives the id from that coordinator is broadcasting continuously. Every XBee in the system would have the same PAN. Is it then possible to display the id on a pc connected to the endpoint via a terminal such as telnet when connected via USB or through an arduino.

Thanks

Every XBee module has a hard coded unique ID which is printed on its tag. This is it 64 bit address and could be used in an RFID like manner.
Read the XBee Document for more info on how to access this address.

I need to be able to set the id to a certain value though

That could be harder. How long of a ID code do you need?
If short then you could set the XBee's IO pin to inputs and tie resistors to Vdd or Vss to produce logic highs and lows. Then setup the XBee the send the pin's input values and read that as an ID.
If you need a longer code then you are probably stuck with adding a processor that sends the ID into the XBee's serial port.
