Funny. Good one!
(I don't want to sound rude, so I did not give numbers. But I meant a small amount of cash compared to what could be at risk of losing if the account behind the card was breached. For example, loosing $1,000 in cash compared to losing a lot of dollars if the account was breached. When the cards are backed by big accounts, it makes you handle the account differently.) "Small" can be seen as relative. Small to Elon Musk is different than small to Ms. Bibbidi.
