What is a Crypto debit card?

Could you please explain what a Crypto debit card actually is? I'm hearing more and more about this new trend, but I'm still not entirely sure how it works. How does it differ from traditional debit cards? Is it secure to use? Can I use it to make purchases anywhere that accepts cards? Also, how do I fund my Crypto debit card, and can I withdraw cash from it? Lastly, are there any fees or charges associated with using this type of card? Thank you for your assistance in clarifying this matter.
