Imagine you’re going to a music festival.
- KDC is like the Ticket Booth: It’s the place where you first show your ID to get a wristband (this wristband is like the Ticket Granting Ticket or TGT). This wristband proves you belong there.
- Getting to Concert Stages: After you have the wristband, you can visit different stages in the festival. But for each stage, you show your wristband and get a special sticker (like the service ticket) that allows you to enter and enjoy the show.
- Why use this system?: It’s safer! You show your ID only once, at the main entrance (Ticket Booth or KDC). After that, you use your wristband to get stickers for other stages. This way, you’re not taking out and risking your ID again and again.
