Electronic seal

An electronic seal is like a special sticker that you can put on a piece of paper or a package. It is special because it has a computer chip inside that can be checked with a computer to make sure it is real and hasn't been tampered with. It's like having a secret code that only the computer can understand and check to make sure everything is okay. This helps make sure important papers or things that need to be kept safe are really safe and haven't been messed with.
