I went for an interview today. Is it appropriate to send information to the examiner?

From the personnel point of view, it is inappropriate.

Just send an email. There should be an e-mail address on his business card.

Mobile phones are more private. Generally speaking, email is a tool needed for normal work. It can be sent and received from time to time, which can ensure that he can receive and reply in time, and it feels more formal.
