Here's a new use for students ID cards that we haven't seen before - cashless payment for tanning services. Sounds silly, but in some sun-deprived states I suppose it's a pretty good idea. It's not unusual for universities to link their ID card programs with local area businesses so students can make purchases with their campus IDs. At many universities, students use their cards for on-campus purchases at bookstores, laundry facilities, copy machines, and snack bars, along with participating off-campus businesses such as movie theaters and restaurants. And now it's even possible for some college coeds to get a tan.
