I paid an ordinary debit card deposit of 100. Now I don't know if I need to pay 30 yuan. At the end of last year, it was said that there was an activity that didn't need to be handed in.

This card is valid for two years. For example, if you apply on 20 10-5- 1, you have to re-verify it on 20 12-4-30, free of charge.

The deposit can be refunded with ID card, library card and his invoice.

Borrowing books/kloc-free within 0/month. If it is overdue, the money will be deducted according to 1 gross/day before 10, and 2 gross/day will be deducted after 1 1 day.
