There is no charge for reader's card. Only when you want to join the lending function, you need to pay the deposit. Now it is free to run a regular reference book, and you can read it in all reading rooms (but you can't borrow it).

Secondary card? Magnetic card? The reader card is an IC card with a chip. If it is like a credit card, it is not available. One reader card per person.

If you want to do it, you must be 14 years old or older, 14- 16 years old, and you must bring your household registration book and notebook. 16 years old or above, just hold a valid certificate. Go to the lobby of the library 1 building, apply on the computer first, and then take the form to the registration counter. There are always staff around. Mace is afraid of injury.
