right but it promises p2p micro transactions
Notice how the MintChip website defines "micro transactions" as anything below $10? Although the video does imply that a "nano transaction" of 1c would be possible.
Also we haven't heard anything yet about the fee structure: the fee per transaction, the fee to load/unload value onto a card, the cost to purchase a card, the cost for hosted iPhone services, etc.
The video and website make a big deal about anonymity, but it's only anonymous between purchaser and supplier. This is the least important kind of anonymity, because you are probably going to give the supplier your delivery address anyway. But you need to give the "trusted agent" your bank account details, because it seems that's the only way to get a card (although no doubt they'll be sold on SR for bitcoins in due course).
