What is Tag Info and what does it show?
Tag Info displays detailed technical information about any NFC tag you scan, including the tag type (e.g., NTAG213, NTAG215, MIFARE), UID, memory size, technology, and whether the tag is read-only or writable.
Can I erase or lock an NFC tag?
Yes. NFC Tool includes dedicated Erase and Format tools to wipe tag contents, and a Lock feature to make a tag permanently read-only. Locking is irreversible, so the app asks for confirmation before proceeding.
