Prepay credit card for Amazon AWS to limit liability?

[jago25_98]

 I figured you guys would actually be some of the best to ask.

What card can I use with limited liability to verify my AWS Amazon account? I want to use Glacier for backup but I don't want my credit card on the hook for an unlimited bill if my account gets breached.

Mixed reports on entropay. Since it's possible to buy gift vouchers and AWS credits (against T&C's btw) actual paying shouldn't be a problem - it's just verification.

 Not looking for privacy, just some liability limit.
