What is the principle that students automatically send text messages to their parents when they enter and leave the school gate? Please elaborate and let me know what equipment to use. Thank you.

"Barrier-free" induction card attendance system adopts non-contact induction card attendance system. Compared with the traditional contact card attendance system, the "barrier-free" attendance system has unparalleled advantages and advancement.

As long as the card is swiped in and out of the campus, the system automatically recognizes and records it, which avoids the data loss caused by forgetting to swipe the card in the traditional card swiping mode and improves the accuracy of students' access information management.

The barrier-free attendance system adopts data interaction mode, which can automatically read cards remotely. This advantage is particularly prominent in the peak attendance period of students going to and from school, which effectively avoids the problems of school gate congestion and inefficient card swiping caused by students' centralized card swiping, and greatly facilitates teachers and students' travel and school management.

The system also supports swiping the card at the school newsletter terminal to make family calls, which provides convenience for children to keep in touch with their parents at any time. Simply put, after using the "barrier-free" attendance system, when students punch in and out of the school gate, the system will automatically send a text message to inform parents to let them know about their children's school situation. For students, the campus card is embedded with the attendance card chip, which is convenient to carry.

At the same time, it is also convenient for schools to keep abreast of the situation of students entering and leaving the school gate at any time to ensure safety. It is particularly worth mentioning that in Wuzhou Xinxing Second Road Primary School, the "barrier-free" induction card attendance system tailored by Guangxi Mobile for the school is also equipped with four snap devices. Once foreigners are found to have entered the school gate, they can check the photos taken by the snapshot equipment through the system to better ensure campus safety.
