I have a small quantity of Chipco RFID chips made years ago when chipco was trying to develop rfid ceramic chips. Ive never seen these appear before however- I am not a collector of gaming chips so perhaps they have.
20.00 ea shipped ( usa sales)
we would prefer paypal to: palmimports@aol.com for payment as it's easy
PLEASE indicate FRID sample on your paypal remittance
...or make me an offer... assuming these dont sell quickly. We're pretty easy to deal with.
when theyre gone- theyre gone

Heres some history we found:
with our chipco asset purchase we also aquired a ton of rfid equipment used by chipco in developing rfid ceramics. we have some start -to-finish molding samples of chips- evidently the molding process was involved to make the tag inside the ceramic blank. The blanks are molded in one shot- not so with the rdif chips. It appears chipco was working with sensysnet as evidenced by the sample rfid ceramics we have.
These chips are chips that have a molded rfid tag. We will also post other chips using a different process as soon as time permits.
