What transponders and air-interface protocols should I use?
There are many different types of RFID transponders and many different air-interface protocols that control how data is written to a tag. There are also different readers that can be deployed, each of which might have a different way of executing air-interface protocol commands. I suggest that you check the reader manual for information about executing write commands for the specific model of interrogator that you are using, and that you call the manufacturer if you are unable to find that information in the manual.
