Yes, NFC tags typically have unique identifiers (UIDs) that are programmed into them during manufacturing. These UIDs can be used to differentiate one tag from another and are often utilized in applications like inventory management or access control to ensure each tag is distinct. However, it's important to note that while the UID is generally unique, it can be cloned with the right tools, so additional security measures may be needed for sensitive applications.
