Mae,

If I understand your question correctly, you want to send data to or receive data from an RFID transponder situated in a field in which there is electromagnetic interference (EMI). I believe whether or not this would be possible would depend on the nature of that interference.

If you were using a battery-assisted passive UHF RFID transponder with a temperature sensor in an area with interference in the 915 MHz spectrum, it is unlikely you would be able to communicate with the tag. If, on the other hand, the interference was in a much higher or lower area of the spectrum, you might. Active RFID transponders with sensors also broadcast a signal, much like a cell phone, and are more likely to have their signal picked up, even when there is some interference in the area.

Your best bet would be to hire a skilled systems integrator who could conduct a site survey, determine the nature of the EMI and assess the viability of the system you are attempting to use in that particular environment.
