Description

This UID card is a passive RFID transponder operating at the 13.56MHz high-frequency band. Its primary technical feature is a writable block 0 memory sector, enabling users to program a custom Unique Identifier. This functionality is critical for system integrators and developers needing to emulate specific card IDs for testing, access control system prototyping, or creating cloned credentials where permitted.

The card is constructed from white PVC, providing a standard form factor (85.5mm x 54mm) and a thickness of 0.86mm for durability and consistent performance in card readers. It is important to note that while block 0 is writable, the card’s factory UID is permanently locked and cannot be altered, a standard security feature of many IC chips.

Key Features

  • ISO14443A Protocol Compatible: Ensures interoperability with a wide range of standard 13.56MHz RFID readers and modules.
  • Writable Block 0: Enables customization of the card's UID for specific application requirements and testing.
  • Durable PVC Construction: Provides a robust, flexible, and long-lasting card body suitable for frequent use.
  • Standard Credit Card Dimensions: Guarantees compatibility with most card slots, readers, and wallets.
  • Cloning Utility: Facilitates the duplication of Mifare S50 card UIDs for authorized development and backup purposes.
  • Stable Data Transmission: Designed for reliable read/write operations at the standard communication distance.

Applications

  • Access Control System Prototyping and Testing
  • Creating Custom ID Cards for Inventory Management
  • Educational Projects for RFID and Embedded Systems
  • Cloning Authorized Mifare S50 Cards for Backup
  • IoT Device Identification and Authentication

Frequently Asked Questions

What does 'writable block 0' mean on this RFID card?

It means the memory sector containing the card's Unique Identifier (UID) can be programmed with a custom value. This allows you to set a specific ID for integration into access control systems or to clone the UID from another compatible card like a Mifare S50 for testing purposes. The card's original factory UID remains permanently locked.

Is this card compatible with Arduino and Raspberry Pi RFID readers?

Yes, this 13.56MHz card is compatible with common RFID reader modules like the RC522, PN532, or RDM6300 that support the ISO14443A protocol. These modules have libraries available for Arduino, ESP32, Raspberry Pi, and other microcontrollers, enabling you to read and write data to the card's memory blocks.

Can I change the UID of this card multiple times?

No, the UID in block 0 can typically be written once per card. After the initial custom UID is written, it becomes locked and cannot be rewritten. This is a standard security feature of the integrated circuit. Ensure your UID is correct before writing.

What are the physical dimensions and material of the card?

The card measures 85.5mm x 54mm, the standard credit card size, with a thickness of 0.86mm. It is made from white PVC, making it durable, flexible, and compatible with most card slot readers and wallets.
