These days schools don't allow students to bring mobile phones to schools.Many parents are worried.How can they connect with their kids at school？Well，smart watches may be the answer to their worries.Smart watches are like small computers.They usually tell time and count a person's steps（步數(shù)）.Most smart watches connect with smartphones and they let the users make calls，and send and receive messages.Often smart watches have microphones and speakers.Some even have cameras.
    Many parents buy smart watches for their children because they are too young to have a mobile phone.They are less worried because they can call their children at any time through smart watches.Also，many smart watches have GPS trackers（追蹤器）.These trackers allow parents to know where their children are，so they know if everything is OK.
    But now some groups in Europe say many smart watches are not as safe as what we think.Some watches allow more than parents to track where the children are. They also allow anyone to send the children a message.People can also control the watches from far away to watch and listen to the children.To be safe，any time a smart watch makes a call or sends a message or GPS information-the information should be processed（數(shù)據(jù)處理） so no one else can get the information.
