What is a Crimson Cash card?

Crimson Cash is the university-wide service which allows you to store money on your id card and replenish your balance with a credit card. 

If you do not have a Harvard ID, you can often procure a Crimson Cash card at the Harvard library you are using.  Alternately, you can purchase cards at Value Transfer Stations.
