What is Mifare Card?
Mifare technology has been shaping the security and access control landscape since its inception in the 1990s & their also have many types of mifare card. Today, it has become an integral part of modern intercom systems for homes, providing convenience, security, and a range of unique features. In this article, we will explore different types of Mifare, how it works and how companies like Vsh are incorporating this technology into their RFID access control products for an unparalleled user experience.
The Evolution of Mifare Technology
Mifare technology was developed by NXP Semiconductors (formerly Philips Semiconductors) in the early 1990s. It is a contactless smart card technology that uses Radio Frequency Identification (RFID) to transmit data between devices. This technology is have many types and widely used for various applications, such as intercoms, access control systems, ticketing, and identification, making it a versatile and powerful solution in today’s world.

How Mifare Works ?
Mifare operates on a 13.56 MHz frequency and relies on the principle of near-field communication (NFC). When a Mifare card or key fob is brought close to a compatible reader, the reader sends an electromagnetic field, which powers the card’s integrated circuit (IC) and establishes a secure communication channel. Data is then exchanged wirelessly between the reader and the card or key fob, granting or denying access based on the information provided.
Types of Mifare Cards and Key Fobs
Mifare technology offers various types of cards and key fobs, each with its unique features and capabilities. The main types include Mifare Classic, Mifare Ultralight, Mifare DESFire, and Mifare DESFire EV2.
1. Mifare Classic
Mifare Classic is the original and most basic version of the Mifare technology. It is available in two memory sizes: Mifare Classic 1K and Mifare Classic 4K. These cards and key fobs use Crypto-1 encryption and are designed for simple access control systems.
2. Mifare Ultralight
Mifare Ultralight is a cost-effective and lightweight solution for applications that require minimal data storage. These cards and key fobs are ideal for single-use or disposable purposes, such as event ticketing or limited-time access.
3. Mifare DESFire & ev2
Mifare DESFire offers enhanced security features and data storage capabilities. It uses Advanced Encryption Standard (AES) and Triple Data Encryption Standard (3DES) encryption algorithms for secure data communication. This type of card and key fob is suitable for more complex access control systems and applications. But for Mifare DESFire EV2 is the latest and most advanced version of the Mifare DESFire series. It offers even greater security, faster communication speeds, and additional features such as proximity checks and multiple application support.
4. Mifare Plus and Plus X
Mifare Plus X is a more advanced version of the Mifare Plus series, designed to provide an additional layer of security and flexibility compared to the standard Mifare Plus cards.
The primary goal of Mifare Plus and Plus X is to facilitate a smooth migration from Mifare Classic to a more secure and feature-rich card, while retaining compatibility with existing infrastructure. This means that organizations can upgrade their security systems without needing to replace all their hardware.

MIFARE vs. Proximity Cards – What’s the Difference?
There are four main differences between a MIFARE and a proximity card. They include:
- Frequency of Operation
A MIFARE card operates at 13.56 MHz, which is equivalent to a high-frequency RFID tag. On the other hand, a standard proximity card operates at 125 kHz. As such, a MIFARE card will have a relatively better read range than the prox cards.
- Memory/ Storage Capacity
A MIFARE comes with a memory to store data. It can store crucial information regarding the cardholder, thus making it ideal for inventory management. The storage capacity of the MIFARE cards differs with the type but averages 1-kilobyte data.
Proximity cards lack space to store data. As such, these cards are only useful when used with pre-programmed numbers to allow access to restricted areas.
- Configuration
A MIFARE card has a unique 32-bit serial number that is programmed from the factory. This number is random and does not have the facility code. On the contrary, 26-bit proximity cards must be configured with a facility code.
- Functionality
MIFARE cards have a wider range of uses than proximity cards. They can be used in different areas, including contactless/cashless payment, road tolling, identification, access control, and fare collection system.
Even better, you can program the MIFARE card with multiple data. This feature allows you to update the card’s details to include all the information that you need for various purposes. Also, the MIFARE memory can be used with pre-paid membership cards and cash cards.
On the contrary, the use of proximity cards is limited to access control. These cards have static numbers that must match those in a pre-programmed reader. After the match, the cardholder is allowed access. The cards do not hold any personalized data of authenticated personnel, which may compromise security.
Summary
In summary, Mifare Plus and Plux X are a versatile and secure solutions for organizations seeking to improve their access control systems. Its enhanced security features, flexible configuration options, and compatibility with existing Mifare Classic infrastructure make it a popular choice for those aiming to upgrade their security without a complete overhaul of their hardware.
