<h2>Introduction to Mifare M1 Card</h2>

The <strong>Mifare M1 card</strong> is one of the most widely used contactless smart cards in the world, developed by NXP Semiconductors. Operating at 13.56 MHz under the ISO/IEC 14443 Type A standard, this card has become a fundamental component in various access control, payment, and identification systems. Its popularity stems from its reliability, security features, and ease of integration into existing infrastructures. The <strong>Mifare M1 card</strong> utilizes RFID (Radio Frequency Identification) technology, enabling wireless communication with readers over short distances, typically up to 10 centimeters. This makes it ideal for applications where quick, secure transactions are essential, such as in public transportation, corporate security, and event ticketing.



<h2>Technical Specifications and Structure</h2>
<h3>Memory Organization</h3>

The <strong>Mifare M1 card</strong> features a 1KB EEPROM memory, divided into 16 sectors, each containing 4 blocks. Each block consists of 16 bytes, resulting in a total of 64 blocks. The first block (Block 0) is reserved for manufacturer data, including the unique identifier (UID), which is crucial for card authentication. The remaining sectors can be configured for data storage, with each sector having its own set of access keys (Key A and Key B) and access conditions. This segmented memory structure allows for flexible application design, enabling multiple functions on a single card, such as storing value for e-purse applications or holding personal identification data.

<h3>Communication and Security</h3>

Communication between the <strong>Mifare M1 card</strong> and a reader occurs through RF signals, using a proprietary protocol that includes mutual authentication. The card employs a cryptographic algorithm (CRYPTO1) for securing data transmissions, though it has faced scrutiny over vulnerabilities discovered in rec The Use of RFID for Human Identity Verification
