There's no way to find out how to find out the meal balance of the children in Tangxian No.1 Middle School on the mobile phone, because the meal card in the school cafeteria is not networked, but actually a card reader. Things that are not connected to the internet can only be read, and the balance cannot be checked by mobile phone.

For example, take a memory card, get an e-book, write a balance, and modify the balance every time you spend, but you can only read cards for things that are not connected to the internet. You can't read the contents of the meal card with NFC, because it is encrypted, otherwise you can modify the balance of the meal card yourself.
