🧩 Comparative Overview: UID Card vs. CUID Card

UID Card: Designed for ordinary copying, these cards allow users to erase and rewrite the 0 sector repeatedly. While they are effective in IC card duplication, they may not perform reliably with firewall-equipped card readers.

🧩 CUID Card: Engineered for enhanced functionality, CUID cards can also repeatedly erase and write to the 0 sector. They are designed to be more resilient, allowing usage even when traditional UID card duplication fails. Additionally, CUID cards have a 90% success rate at bypassing firewall restrictions, making them a superior choice for advanced access control systems.

⚡ Note: It is important to note that common 13.56MHz RFID reader/writer devices are not capable of writing on CUID cards. To ensure optimal performance, compatible NFC and Android apps such as MCT, 300CD, PM5/Pro, ACR122U, and iCopy3/5/8 are recommended.

Enhance your access control and identification processes with our reliable and innovative CUID cards, designed for flexibility, durability, and a range of applications.
