In your judgement how common do you feel this exploit would be across other university IDs in the country, or just IDs in general? Did your research uncover any data in that regard one way or the other?

I'm just remembering my ID card...and my sister's...and my brother's. We used those for literally everything.

While my research was specific to OSU, I do know that this is a larger issue than just my alma mater. I collected student IDs from other colleges, but did not publish them as I didn't want to get into hot water.

The thing is though, a lot of these magstripe systems have problems. We brought up in the presentation that Walmart at the time was having a large problem with people encoding stolen credit card data onto gift cards. Cashiers at the time did not check driver licenses when paying with a gift card.

That is top-quality social engineering.
