# NFC Magic This application allows you to check whether your NFC card is Magic, write data to Magic cards, and restore them to their original state. ## What's a "Magic" Card? A Magic card is a card that allows you to change its UID. Generally, NFC cards have a UID pre-programmed at the factory, and it cannot be changed. However, some cards have a special backdoor feature that allows you to change the UID. These cards are called Magic cards. ## Supported Cards Currently, not all Magic cards are supported.
