All RebelCards issued after May 2018 have One Card capabilities and door access can be added to them. You can check if your card has this ability by looking for the six digit number on the back (as pictured in the red circle). To have building access added to your card, you will need to contact Facilities Management and give them the six digit number on the back of your card. If there are no numbers on the back of your card, you will need to come to the RebelCard office to have an updated card issued to you.
