If your old campus card is still valid for your current enrollment status, you may activate it on the campus card self-service machine. Please note that only one campus card is valid for use at the same time. If you have already obtained a new campus card and activate the old one, the new card will immediately become invalid. The specific steps for "Old Card Activation" are as follows:
1. Click the "Old Card Activate" option on the self-service machine interface.
2. Log in by entering your campus card account number / student ID / employee ID and campus card password, or by using the "Scan" feature in the "My SJTU" app for identity verification.
3. After logging in, place your campus card on the card reader area of the self-service machine as prompted on the screen, then click "Activate". Then complete activation of the old card.
