No one wants to lose their MagicBand, but it does happenMany people worry about what will happen if they lose a MagicBand, especially if they are staying on property and have a debit or credit card linked to it. Relax, no one will be able to use your card. You will have already created a PIN in order to charge something. (If someone somehow does guess your PIN, remember that there are cameras everywhere!) Report the loss of your band right away, and Disney will cancel the number.
