we got these 900mhz band RFID tags available from mouser.com as part number SL3S1202AC0,118 they cost 8 cents each. http://www.mouser.com/ProductDetail/NXP-Semiconductors/SL3S1202AC0118/?qs=sGAEpiMZZMvQHWqrh58LgXtw8BZ1psdi%252bSfsWYs2XZg%3d

the picture on the mouser site is wrong for these parts, they do not look anything like a 1206 capacitor.

these tags do not have an antenna - they are a grain of sand in the middle of a 3mm x 9mm piece of plastic. On either side of the grain of sand is a copper contact that you can solder to if you're careful. don't melt the plastic backing! the whole thing will probably stick to whatever it was resting on when you soldered it, so prepare. Make your antenna (a loop of wire probably, we are trying to figure out what works best) and solder it to the two contacts and then protect the thing with some hard (hitemp) hotglue or epoxy or something.
