Harvard Key Login:

We are experiencing intermittent issues with Harvard Key Login which may prevent you from adding value to your Harvard ID via Credit Card or Bank Account. If you experience this issue, please add funds using the Proceed as a Guest button which can be found by making a selection from the Add Value Now menu.

Welcome to Crimson Cash

Crimson Cash is a declining balance convenience account accessed through your Harvard ID card. Anyone may Add Value to your account but only you, with your Harvard ID, can make purchases.

Crimson Cash is the safest, fastest, easiest way to buy the things you need including at select Off-Campus merchants, on campus retail and dining locations, vending machines, laundry, copying and printing (see website for list). Using this website, you can quickly Add Value online, 24 hours a day, 7 days a week.

If you have a Harvard ID, then you already have a Crimson Cash account! No sign-up form is required. Your account is already open and ready for you to add value in one of these ways:

  1. (Credit Card)

  2. (Bank Account)


New ID Cardholders

You can Add Value to your Crimson Cash account after you receive your permanent photo ID card, but unfortunately, not beforehand since you need the 16-digit CC number which is found only on the BACK of your ID card. For security reasons, this number cannot be obtained thru any other means.
