This glue is used to prevent the card from falling off, which may cause the card to slip off and bring unnecessary trouble to the cardholder.

When making a card, the card sticker and the card number are attached quickly after passing through the high temperature on the card punching machine, and the card can only be forcibly taken out of the card insertion letter.

So, don't worry, it won't stick to it. Even if you put it on it, you can use it when you take it off.
