Families can add values ranging from enough for one single ride to a month’s worth of usage. When students use the card, each ride is deducted from the card at the reduced student rate. Switching to this type of card reduces the cost for students who use the MBTA sporadically and does not significantly increase the cost for unlimited monthly use. The main difference is that once a student has the registered card, families put whatever funds they want on the card themselves rather than going through the school.
