🤖 CUID Black Card 13.56MHz IC Cards - Access Control NFC Smart Chip Badge
🤖 The CUID Black Card is a state-of-the-art access control solution designed for seamless integration with NFC technology. Operating at a frequency of 13.56MHz, this advanced smart chip badge is specifically engineered for versatility and security in various applications.
🔧 Key Features:
- Customizable UID: With a block 0 that can be arbitrarily modified, this card provides the flexibility to personalize the Unique Identifier (UID) according to your specific requirements.
- Default Password: The card comes with a preset default password of 12 F's (FFFFFFFFFFFF), ensuring a basic level of security for initial access and configuration.
- NFC Compatibility: The CUID card supports Android NFC applications, enabling users to utilize the MCT app for easy UID modification. This allows for straightforward updates and changes to the card's settings, making it an ideal choice for dynamic environments.
🌟 Understanding UID vs. CUID Cards:
The CUID card differentiates itself from traditional UID cards in several significant ways:
- UID Card: An ordinary copying card that facilitates the repeated erasure and rewriting of its 0 sector. This type of card is typically used in IC card duplication but is susceptible to failure when interfacing with card readers equipped with firewalls.
- CUID Card: A more advanced, rewritable anti-shielding card that also allows repeated erasure and writing of the 0 sector. It excels in scenarios where UID card copies are ineffective, able to bypass firewalls in approximately 90% of cases. Additionally, it supports modification via the Android MCT app, adding another layer of convenience and adaptability.
⚡ Important Note: Standard 13.56MHz RFID reader/writer devices are not compatible with CUID cards, emphasizing the need for specialized equipment when working with this innovative technology.
