The University of Calgary will stop accepting tuition payments by credit card, following in the footsteps of several other Canadian universities.  More than 600 uCalgary students have signed a petition, and about 60 marched last Friday to protest this decision.  Cutting credit cards will save the university up to $700,000 per year in transaction fees, which they say could be channeled to scholarships.  Students are frustrated that they were neither consulted, nor given notice of the decision.  The new policy goes into effect on July 1, and was announced in mid-March.  Many students say they will have no way to pay, if credit cards are cut. CBC
