An RFID book detection system for school children may comprise a plurality of book jackets, at least an assignment system, and a school bag. The book jackets respectively fit around different books, and each of the book jackets has a corresponding RFID tag on a surface thereof. The assignment system is provided for saving and managing input information including at least a curriculum and RFIDs on the RFID tags, and the school bag used for placing the books comprises a sensor which is connected to the assignment system to check whether the books in the school bag are exactly the same as the next day's course schedule on the input curriculum saved in the assignment system. Thus, the child can scan the RFIF tags on the book jackets one by one before putting the books into the school bag, which helps child to learn packing his/her school bag independently.
