Here are some examples:
* Se requiere un pasaporte válido. (A valid passport is required.)
* Se requiere experiencia previa. (Prior experience is needed.)
* Se requiere la firma del cliente. (The customer's signature is required.)
It's important to note that "se" in this context is a reflexive pronoun, meaning that the action is being performed on or to itself. So, "se requiere" translates to "it is required," with the "it" referring to the object or action being required.
