I take it they measure the spin of some particle and then automatically know the spin of an entangled particle a distance away (by the Pauli Principle).
They do transfer "information" by sending a particle somewhere, but the receiver has to know about the result of the measurement of the sender particle to know the spin of his own recieved entangled particle. And that information can only be distributed by the speed of light (at a max). However, the sender will think that information has been transmitted instantaneously, because his measurement concludes the result of a measurement any distance away, but noone can use that information unless the result of the measurement reaches them first.
The particle in itself is a transfer of information but the state-measurement isn't. It is probably impossible to transfer information instantaneously (at least if the theory of special relativity is correct and that seems to be the case).
