If you run out of money, you can add more to your VCU card through Value Transfer Stations at various locations in campus or online on VCU Card website.
You can also use your VCU card as an ATM card at WellsFargo ATMs located on the campus. For this you need to take your VCU card to a Wachovia branch and tell them to activate it.
Access to buildings:
Some buildings require your VCU ID for after hours access if you want to work in your lab late night or on weekends. You need to contact your department to get access to the building that you are working.
