Where can I use Coinbase card?

Excuse me, as a cryptocurrency enthusiast, I'm interested in exploring the usage of the Coinbase card. Could you please elaborate on where I can utilize this card? I've heard it's a convenient way to spend my crypto holdings, but I'm not entirely sure about the specific places where it's accepted. Are there any restrictions on its usage, such as specific merchants or locations? Additionally, is there a way to check if a merchant accepts the Coinbase card before making a purchase? I'd appreciate any information you can provide to help me navigate this new payment method.
