Do you mean using RF..
isf thats what you mean ,yes you can,say from PIC to PIC or PIC to PC and vice versa

you get OEM radio modules like Ming and Radiometrix.

You need to give serial data to the radios like the radiometrix.Some of them need to be given a Preamble at the beginning of a transmission ,so that the radios sync with each other.you can even include manchester encoding into your code.

I don't know if this is what you mean,... but I have been looking into a interface to read a contactless credit card. also known as smartcard, BLINK, or paypass.

Some banks are implimenting these, and I want to suck a user name and address out of it. (but I won't be doing the credit tranaction).
