Interesting. All these implementations seem to be limited to use
online though, which doesn't really solve the data security problems

For something like this to really have an impact, it would have to be
designed and officially supported by VISA and Mastercard, and would
have to work at Brick-And-Mortar merchants just as well as online
merchants. Without using some kind of token device, I don't see any
way that could be done today.
