A mifare classic 4k card

The Mifare Classic 4K card is a type of contactless smart card developed by NXP. It uses RFID radio frequency identification technology to communicate with a reader device wirelessly.

Key Features:

  • Storage Capacity: The storage capacity of this card is 4 Kilobytes (4K) of data. It is larger than the standard Mifare classic card 1kb. The “4k” in the name refers to the card’s significantly higher memory capacity of 4 kilobytes compared to the standard 1kB memory of mifare classic cards. This allows for storing more data on the card, such as additional access control information, user profiles, or even small amounts of financial data for low-value contactless payments.
  • Security: It uses a basic security mechanism to divide the memory into sections. Whereas the most sophisticated security system, it makes suitable for applications where data privacy is very not critical.
  • Applications: It is commonly used in high volume transactions where data storage is important. Most commonly include transport ticketing, access control systems, loyalty programs, and contactless payments.
  • Some additional details:
    • Operating Frequency: 13.56 MHz.
    • Read/Write Speed: 106 kbit/s.
    • Durability: Made from non volatile memory (EEPROM) that retains data even without power.
  • Summary:  The mifare Classic 4K card offers a larger data storage capacity than the standard Mifare Classic card, making it suitable for applications requiring more information storage. However, its security features are relatively basic.
