Honey. . Which school are you from? . Our school has a new all-in-one card ~ ~ The old one can only be used to fetch water and so on ~ Because it is an old card ~ But the small wallet is separated, so the money in the original small wallet has not been converted into a new card, so the new card can only be used with the small wallet, and the old card can not be used for other things, that is, the money in the original small wallet can be thrown away when it is used up. The library can only handle a new card.
