First of all, find the thawing equipment or terminal designated by the school, which can generally be found in the school library, campus card service center and other places. Then, insert the campus card into the corresponding card slot and wait for the device to read the card information. Next, select the unfreeze function, and enter personal information such as name and student number according to the prompt of the device for identity verification. The system will verify the input information, and if it meets the thawing conditions, the system will automatically unfreeze the campus card. After thawing, retrieve the campus card, and make corresponding recharge or other operations, such as purchasing catering and borrowing books.
