It becomes a hard wallet after you pop the chip, so you can load all your data onto it then pop the chip and no more data can be loaded onto it.
Essentially the idea is once you load an amount onto it you can pop it and give it to someone or use as a self limiter (ie you only want to spend 100$ at DEF-CON but know you wont be able to resist the ATM's in Vegas)

Gotcha. That's really neat. It's refreshing to see some HQ posts here like this. Kudos!
