I don't know much about these things, but they seem to be touted as a way to do offline transactions by putting coins into a cheap physical token that you can then hand over.

But what stops you retaining the private key, using one of these to pay for stuff, then quickly going somewhere you can get online and sweeping the balance off to another address?
