What is a hashed credit card?

I'm curious, could you explain what a hashed credit card is? I've heard the term mentioned in the context of online security and transactions, but I'm not entirely clear on how it works. Is it a type of encryption method specifically designed for credit card information? How does it differ from other forms of data protection, and why is it considered to be a secure option for safeguarding credit card details? I'd appreciate it if you could provide a concise explanation that breaks down the key points and benefits of hashed credit cards.
