Short-range RFID does not need a power source. When you wave or touch it to a receiver, there is a magnetic field surrounding the receiver, which induces a current in the very small circuitry, enough to make it transmit a fixed code for a very short distance (inches generally at most).

What the battery appears to be for is where Disney mentioned that if you are close enough to some special sensors, it will pick up your band's transmission and be able to do things - whether this is some sort of custom experience trigger mechanism, or them sending you a "Hey, you're near Pecos Bill's - how about a rootin'-tootin' burger? $1 off" message, we don't know yet. But that needs to work over a longer distance, hence the battery for a stronger transmitter. It might even send a completely different code for security (supposition on my part).

There does not appear to be an on-off switch to turn that transmitter off, which is why I think it has limited life. And whether they will let you use just the RFID part without the transmitter part when the battery dies, I don't know.
