Recently, according to the Yucai Middle School of Shenzhen Shekou Yucai Education Group, the students of the school's science and technology innovation society invented a smart schoolbag called "zhianqi - RFID based smart schoolbag". The schoolbag will remind the students to carry the books they need for the day according to the schedule. When there are books missing or too many, the bag will make a "tick" sound, showing the books with less or more.

The invention won the first prize of the Shenzhen Special Prize in the eighth "Internet" College Students' innovation and entrepreneurship budding track project Shenzhen trials, and successfully entered the Guangdong Provincial semi-finals.

Zhianqi - Smart schoolbag based on RFID radio frequency, inspired by the small troubles of life that students often encounter - books are scattered, and the time to pack schoolbags is too long. In order to improve the efficiency of packing your schoolbags and help you form a good habit of whole books, 15 members of Yucai Middle School Science and Technology Innovation Club worked together to develop this unique intelligent product.

"Zhianqi" schoolbag has the advantages of accurate scanning, regular reminder, class schedule display, simple operation and long endurance. It uses radio frequency identification technology to realize non-contact two-way data communication, and uses radio frequency to input and identify the information of books with RFID tags, so as to achieve the purpose of identifying books.

Combined with their own needs and the results of the questionnaire survey, members of the science and technology innovation society created and developed this smart schoolbag, which was named "zhianqi" - smart, reassuring and complete. From the initial hand-painted drawings to the scanning hardware capture of version 1.0, and then to the function and appearance of version 2.0, "zhianqi" was finally perfectly presented in this competition after the time of these 15 students, which was inseparable from the hard work of every member.

After the product was formed, members of the science and innovation society also conducted a series of offline tests, such as inviting students from junior high schools and primary schools to experience this smart schoolbag. The experience activities have not only been highly praised by everyone, but also received many effective feedback, so that the product functions can be better improved and perfected in the subsequent research and development. One of the parents of the students who participated in the experience commented, "if our children can use this schoolbag when they are in kindergarten, it is really great and very worry free!"

The completion of "zhianqi" not only has an impact on students, but also provides a new idea for RFID major enterprises when developing products.
