Transporter credit
Transporter credits were a rationed unit of exchange that allowed for use of transporters at Starfleet Academy in the 24th century.

Within his first five days at the Academy, future Captain Benjamin Sisko beamed back to his home in New Orleans each day for dinner. By his son's estimate, he likely had used up nearly an entire month's worth of credits. ()
