That’s correct. It doesn’t really specify the location except within the designated perimeter.
I have a card that allows me to freely enter very large security area. They recently implemented a policy for visitors to sign at the exact location they are visiting. That means they have some problem with unauthorized wandering by visitors with the passes. They had the policy before but abandoned it. I suppose the problem is happening again.
For a school, the card entry data is important. It can be used as a roll. The calling of the roll becomes unnecessary. The computer knows who came and when and when they left. The numbers provide a record to be submitted for funds provided on a per capita basis. The data also are basis for truancy situations, for tardy problems and on and on.
For a manager, the principal, the auto collected data is a great tool. All the fear is ridiculous. The process is the way the world works now.
There are tens of millions of people using things like EZ-Pass that don’t require them to stop to pay the toll on a road. Of course, that means they could eventually be used to know where a lot of people are and where they have gone. And how far they drove. And how long it took them to get there. And what their average speed was. And so on.
Could be very useful info for some governments wishing to control people.
