Campus Cash is the easiest way to make purchases at UB because it's accepted by the best places on campus and many businesses off campus, too. Purchases made with Campus Cash are taxable. You can even use Campus Cash to buy Dining Points, and using Dining Points will save you money on your meal purchases because you don't have to pay tax.
There's only one way to spend your Campus Cash - by using your official University ID, the UB Card.
