What Stands Out
Changeable UID
The GEN2 CUID keyfob allows users to modify the UID easily, enhancing security and personalization compared to static tags, making it ideal for varied applications.
High Compatibility
Operates at 13.56MHz and supports NFC standards, ensuring seamless integration with most NFC readers, devices, and applications in both personal and professional settings.
Writable Memory
With Block 0 being writable, users can store custom data or commands directly on the tag, offering smarter access solutions and improving convenience for frequent users.
