but the websites do not sale the chip , usually they sale the RFID tag or reader . for me i need just the chip

Alien itself sells Higgs-4 in two package-types: flip-chip and SOT. The former is more compact, however it requires ACP for bonding. The latter is more friendly for prototyping since it can be soldered. You can contact the Alien sales to buy the chips. But note that there is a MOQ (minimum order quantity) requirement for such purchases, usually on order of thousands at least. You may need to contact some local RFID distributor for chips of a small amount.
