SU I.D. cards are RFIDs that contain a proximity chip in the top left corner. There is also an antenna wire running around the entire edge of the card.
Please do not puncture or alter the card in any way.
Does your card have an RFID chip inside?
ID cards printed since 2014 have had an RFID chip inside. If your card is orange and has a picture of the dome on the front, you have an RFID card. If your card is orange and has a picture of the Hall of Languages on the front, please request a new card and you may select damaged card for the replacement. You will not be charged to replace your card to an RFID card.
