These are prepaid debit cards, so they can be used just like any
regular debit card. Online, in stores, ATMs, etc. are all valid
locations to use the cards. Do I have to hide my identity while using these cards? No, again these are prepaid debit cards that have no owner but you, which is what makes them risk free cards.
