Is Dash a prepaid card?

Could you please clarify if Dash, the decentralized digital currency, is essentially a prepaid card? I'm aware that Dash aims to provide faster and more secure transactions, but I'm uncertain if it functions in a similar manner to a traditional prepaid card, where funds are loaded onto the card and can be used for purchases until the balance is depleted. Does Dash operate on a similar principle, or is it a fundamentally different type of financial instrument? I'm interested in understanding how Dash works and how it differs from other payment methods.
