Student laundry?
sdt: http://www.collegebellhop.com/College Bellhop does this, but with long-term pricing: you pay for a term, not for a load of laundry. There were a few people that used it where I went to school.It always seemed overpriced to me. I realized early on that the card-based laundry systems tended to have very simple control outputs, so all you had to do was pop the cover off and short the right connections--bam, free laundry. Errr, not that I ever did that.
