Hi again
I'm designing a database for students to sign in and out of school. It is based on a card scanner, which works for signing in, but I'm unsure about how to get them to sign out. I would like to know: How can I make it so that when the student swipes their card, a check is made to see if they are signed in. If they are not, it signs them in, but if they are, it enters the current time to the 'timeout' field.
Thanks for any help
