About Guest TechCASH:
If you lose your guest TechCASH card it's like losing cash, unless you register it with the MIT Card Office. Unregistered cards cannot be replaced if lost or stolen.
Note: If you've added value to a Guest TechCASH with a credit card through the TechCASH web site, your card is already registered to you.
