What is a Plutus Crypto debit card?

Could you elaborate on the concept of a Plutus Crypto debit card? I'm curious to know how it functions and how it differs from traditional debit cards. Specifically, I'm interested in understanding the role it plays in facilitating cryptocurrency transactions. Does it allow users to directly spend their digital currencies in the real world, or does it convert them to fiat currencies first? Additionally, I'd like to know about the security measures it employs to protect users' funds and transactions. Lastly, I'm wondering if there are any fees or limitations associated with using a Plutus Crypto debit card.
