MIFARE DESFire From NXP
MIFARE DESFire from NXP is the latest generation of contactless smart cards. Featuring high levels of security and NFC compatibility, it is suitable for a wide range of applications including access control, loyalty and micro-payments.
These chips use DES, 3K3DES and AES hardware encryption during communication with a reader. They also offer a secure memory organization structure.
EV2
The second evolution of MIFARE DESFire, the EV2 chips offer superior performance and state-of-the-art security. It features a transaction timer, configurable ATS information for card personalization and the new Secure Unique NFC (SUN) function which is mirrored as text into the NDEF message (compatible with NTAG DNA).
It operates at a distance of up to 100mm. Its robust microcontroller architecture offers a high number of read/write cycles and supports up to 28 nxp mifare desfire different applications using a flexible memory structure and mutual three-pass authentication techniques.
Using a programmable application directory and 128-bit AES encryption, the EV2 chip is compliant with ISO 14443A and has CC EAL 4+ card security rating. It has an on-chip backup management system and is able to load new applications after the product is deployed in the field for enhanced interoperability.
Gallagher offers a range of standard MIFARE DESFire EV2 cards, allowing you to choose the right solution for your application. All EV2 cards are encapsulated into PVC material and come with punch holes to enable them to be used in smartcard applications.
EV3
With a secure key encryption system, DESFire EV3 is the latest in MIFARE technology from NXP. This new chip provides a higher level of security for access control applications, including the ability to protect against spoofing and hacking attempts. It also provides a random UID, which helps ensure that no two cards ever share information that could identify the cardholder.
A reliable, high-speed chip for transport ticketing systems. It features an on-chip backup management system and triple DES data authentication. Its open concept allows for tailored integration into a variety of ticketing formats, including keyfobs, Combiwatches and mobile tickets.
The EV3 is designed to be compatible with older MIFARE EV2 and EV1 readers for an easy upgrade. It also has a higher number of read/write cycles than previous versions and supports NFC-enabled smartphones, including Samsung Pay. It is also designed to support the SUN Message protocol for secure dynamic messaging. This allows for a more secure and connected smart city environment. It also enables closed-loop payment solutions, as well as logical and physical access control applications.
Light
A secure contactless smart card with a built-in microprocessor that uses DESFire encryption to prevent the unauthorized copying of data from the card’s chip. The DESFire-based cards are ideal for access control, public transportation and event ticketing.
The IC (integrated circuit) includes an extensive set of security features that help protect against unauthorized data access and cloning. Its hardware and software are Common Criteria EAL 5+ certified, and it supports a wide range of open crypto algorithms. In addition, it has a transaction timer feature that helps mitigate man-in-the-middle attacks.
The POST /desfire/ev1/deleteApp API allows you to delete the applications on the card. This only works if the application uses AES for security and only the owner of the app holds the keys to decrypt the information stored in the file. If an application has not been encrypted, Fidesmo cannot remove it from the card. This is a security issue and it is not recommended to use unprotected applications on the card. We offer a large variety of DESFire cards that come preloaded with a number of different applications.
Classic
MIFARE Classic chips are the most widely used contactless chip in the world. They are incredibly versatile and can be used in a variety of different systems, including transport networks and university access control. They are also backwards compatible with older MIFARE DESFire generations, so that a system developed for one generation can be used with the next.
Unlike the MIFARE DESFire EV2 chip, Classic cards are preprogrammed with a fixed memory structure with sectors that contain three blocks of 16 bytes each. This structure makes them less flexible than the EV2 chip, which can hold multiple applications. Nevertheless, the chip can be reprogrammed in the field to add new features.
Despite this, NXP’s DESFire Light chip offers an impressive array of security features. It supports up to five customer-defined AES 128-bit keys, mutual 3-pass authentication and a transaction counter. It also includes a random ID and an elliptic-curve-based ‘originality signature’ to ensure data integrity during contactless transactions. The chip’s hardware and software are both certified to Common Criteria EAL4. The IC is able to clone cards in about 100 milliseconds, and its security mechanisms prevent spoofing.
Magstripe
The MIFARE DESFire chip is one of the most popular and versatile contactless chips available. It’s a small integrated circuit that can be used in a wide variety of systems including logical access control, loyalty and micropayments. These chips use a unique encoding system that provides high security and reliability.
The DESFire chip features a simple application directory structure and uses 128-bit AES hardware encryption to protect data transmission. Moreover, it offers a number of security options such as a transaction counter, an elliptic-curve-based “originality signature” and a secure messaging mode.
In addition, the DESFire chip has a longer read range mifare desfire than its predecessors. This means that you’ll be able to use it in places like Point-of-Sale, meal systems, libraries and transportation.
This latest product from NXP is the newest version of the MIFARE DESFire family. It was launched in June 2020 and has a few new features that make it more secure than its predecessors. Its key features include a card generated MAC, which helps prevent man-in-the-middle attacks and a new Transaction Timer feature that helps mitigate these attacks by setting a maximum time limit for transactions.
