Is there a passive chip that can do this?

I’m trying to think of a technology that would allow me to communicate with a passive object (that is, doesn’t use electricity) no more than a meter away. I was thinking RFID or NFC but I don’t know enough about the two to say for sure. Any suggestions? Specifically I need to find a way to track a thin, passive device less than a meter from a powered device. Just so I know the position of the passive device relative to the powered one.
