Ok, I am intrigued by this. Will this work like the old Casascius physical bitcoins, where you have the private keys stored on the physical coin or card or will this be administered by a third party and this card will just link you to their internal database via the Semiconductor’s S3D350A chips?

So will the manufacturer of the cards be in control of the private keys or would the private keys be stored on the chip? The ownership of the private key is the most important factor in this technology.
