These can be used to get your student or staff discounts at the SU, get access to Columtreal only events, and if you can find the right person on campus, get yours doctored to show an incorrect date of birth giving your character a legit fake ID.
To get your legit cards show up to any CU orientation meeting on the calendar and provide a plain photo of your character with a white background.
To get a doctored card - RP around campus and with a bit of tenacity, you might find your guy - or girl and provide a doctored photo in an attempt to make your character look older. Again white background.
