Identity Card Security

This article is an assessment of the security risks of MIT’ student cards which are used for identification, building access, charging meals, etc. This article was written a while ago but I would imagine that a lot of the problems still exist. The main problem is that such cards are easy to duplicate and hack. Also, using a single card for diverse requirements makes them even more vulnerable. MIT’s student card isn’t unique in this regard. It’s likely that any card using similar broadly-available technology is vulnerable to duplication and hacking.
