What is a TRC card?

Can you explain to me in simple terms what a TRC card is? I'm not too familiar with the intricacies of cryptocurrency and finance, so I'd appreciate it if you could break it down for me. Is it a type of physical card that's used for transactions, or is it more of a digital asset? And how does it fit into the broader cryptocurrency ecosystem? I'm curious to learn more about its purpose, benefits, and potential use cases.
