School Communication Pass, School Communication ID Card, School Communication IC Card

The School Communication Card is essentially a communication platform between parents and schools through communication technology, allowing real-time monitoring of students' movements! Anyone who can find the Xiaoxun Tong card must be well aware of its function. Today, on our professional card platform, we won't introduce the product's uses, but will provide a comprehensive parameter analysis of the card!

Once, a friend gave me a Xiaoxuntong ID card. Through technical analysis, I obtained the following parameters and posted them for everyone to understand!
