ID CARDS AT WORK AND SCHOOL

My father and my mother are bankers and they work at the same bank. At the bank, they have to wear their ID cards all the time. On their cards, they have got their photos, their names, and their positions of work. They always leave the cards at the bank so they never forget them.

I heard that some schools have ID cards for their students, too. These cards are for the safety of the students. When students enter school, there is a machine that students use to scan their cards. When a student leaves school early or never comes to school, the principal can easily find it out and they call and inform parents about it.
