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.
