tritonplus is like a debit card (but its your id card) that you use on campus for things like laundry, anything at the bookstore, jamba, panda, all the other restraunts on campus, any coffee stands....you can also use it at certain stores off campus...i use it at the chipotle thats close by...you just add money on it online and the money thats on it transfers from year to year so it wont disappear, and you dont get charged for using it or anything..it makes the little things on campus easy to do...when youre not at the dining halls you dont really need a wallet just your id..and not dealing with quarters for the laundry is nice
