    The person on IRC informs me that the SD standard supports things other than block devices. These may be real "smart cards" in a micro-SD form-factor.

    The protocol would seem to indicate that is the case.  The chip stores an irrevocable keypair.  The chip signs tx with private key which can be verified by other uses with the public key.  The chip decryments the value on spends and increases value on payments. 

    Still the underlying problem still exists.  The attack vector is to remove private key(s) from the chip.  Once you do that you can forget payment tx which can't be detected by the other party.  Essentially print money out of thin air.  All the profit of counterfeiting without all the physical printing overhead.
