Transmitter ID	Each transmitter has a unique ID that can be assigned to individual students, or it can be used in a registration ID mode where students self-identify.	Each student’s response can be tied directly to him or her.
Low Cost and No Recurring Fees	Transmitters are owned by the student or purchasing institution. There are no online or registration fees assessed to activate the transmitter.	Saves significant money over multiple semesters and for students using the transmitters in multiple classes.
