Mifare Cards

Mifare Classic cards have either 1K or 4K of EEPROM memory. Each memory block can be configured with different access conditions, with two seperate authentication keys present in each block.

Mifare Classic cards are divided into section called sectors and blocks. Each “Sector” has individual access rights, and contains a fixed number of “Blocks” that are controlled by these access rights. Each block contains 16 bytes, and sectors contains either 4 blocks (1K/4K cards) for a total of 64 bytes per sector, or 16 blocks (4K cards only) for a total of 256 bytes per sector.

The Physical Characteristics of a Mifare card:

  • operating frequency: 13.56 MHz.
  • read range: from about 0cm up to 10 cm.
  • card size: approx. 85.7mm x 54.0mm x 0.8mm.
  • data capacity: a standard 1K Mifare card has 16 sectors each with 4 blocks of data that are 16 bytes. Other capacities are available.

Mifare card are a type of contactless smart card that have become increasingly popular in recent years due to their convenience and versatility. These cards are used in a wide range of applications, from public transportation systems to access control systems and more. In this essay, we will explore the technology behind Mifare cards, their benefits, and some of their common applications.

Mifare card are based on a technology called RFID, which stands for Radio Frequency Identification. This technology uses electromagnetic fields to automatically identify and track tags attached to objects. In the case of Mifare cards, the tag is a small chip embedded in the card that contains information such as the card’s unique identifier and any data that needs to be stored on the card.

One of the key benefits of Mifare card is their contactless nature. Unlike traditional smart cards that require physical contact with a reader, Mifare card can be read from a distance of several centimeters. This makes them ideal for use in situations where speed and convenience are important, such as in public transportation systems where passengers need to quickly board and exit vehicles.

Another benefit of Mifare card is their security. These cards use advanced encryption algorithms to protect the data stored on the card and ensure that only authorized individuals can access it. This makes them ideal for use in access control systems, where they can be used to control entry to restricted areas and prevent unauthorized access.
