Beam it to me

Yoshiko and Megumi exchange telephone numbers first day in class after sudoku.

Yoshiko: What’s your phone number?

Megumi: I’ll call you and then you’ll know.

Yoshiko: But you’d have to enter my number. It’s just quicker if I beam you mine and you beam me yours.

Megumi: Okay. Beam me, now, go.
