MIFARE DESFire EV1 Contactless Smart Card

MIFARE DESFire EV1 cards are ideal for customers who need secure multi-application smart cards for public transport schemes, access management or closed-loop e-payment applications. These smart cards fully comply with the requirements for fast and highly secure data transmission, flexible memory organization and interoperability with existing infrastructures.

The MF3ICD21 and MF3ICD41 chips in these cards use 128-bit AES hardware encryption to prevent side-channel attacks. They also feature a proximity check and key management system to prevent cloning of credentials.

EV1 is a contactless smart card

The EV1 contactless smart card allows you to add multiple applications to your existing system, while providing a high level of security. It is an ideal choice for organizations looking to enhance their credential-based security and increase value from their smart card investments. It offers the ability to combine a range of different applications, including access control, event ticketing and cashless vending. It also enables users to use their credentials with NFC-enabled devices, including mobile phones and tablets.

The MIFARE DESFire EV1 card uses an NXP MF3 IC, which provides a contactless transmission of data and energy between the card and reader. This technology complies with the ISO 14443 standard and operates at a maximum distance of up to 10 centimetres (3.9 in). It has a non-volatile 8Kbyte memory, a fast triple DES encryption coprocessor, and a flexible memory organization structure. Its on-chip backup management system protects the data in case of a power failure, and it uses an AES cryptographic protocol with mutual 3-pass authentication.

It is an excellent choice for public transport schemes and access management, as it supports multi-applications in a highly secure environment. Its byte-level layout makes it difficult for reloading attacks to be successful. MIFARE DESFire cards also have a transaction timer, which reduces the duration of message delays between the card and the reader. This helps to mitigate the threat of man-in-the-middle attacks.

EV1 is a contactless NFC smart card

The MIFARE DESFire EV1 contactless smart card is a high-security chip that works with the Near Field Communication (NFC) technology. It provides a perfect balance of speed, performance and cost efficiency. It is based on open global standards for air interface and cryptographic methods. The chip offers an excellent level of security by using a DES, 2K3DES or AES hardware encryption engine to encrypt transmission data.

The EV2 chip also has a more robust cryptographic architecture, providing superior protection against side-channel attacks that were known to affect the original MIFARE desfire ev1 DESFire. In addition, the EV2 chip has enhanced proximity control, which prevents relay attacks by putting stricter limits on the amount of time that can pass between sending a command from the reader and receiving an answer from the card.

MIFARE DESFire cards are ideal for use in applications that require high levels of security, including access control and biometric identification. They offer 8 Kbytes of dynamic memory, arranged into easy-to-define application folders and data files. The chips are also compatible with the HID MIFARE DESFire Card Printer, making it easier to produce cards for a variety of applications.

MIFARE DESFire cards can be produced with visual security and anti-counterfeiting features such as holograms, ultra-violet fluorescent inks or micro-printing. They can also be made with a customized logo, making them easier to identify and verify as genuine.

EV1 is a multi-application smart card

MIFARE DESFire EV1 is an advanced contactless chip designed for use in multi-application smart cards such as public transport schemes, access management and closed-loop e-payment applications. It supports all well-known commands and features from DESFire, but with additional enhancements such as secure dynamic messaging. Whenever a card, ticket or mobile is tapped with this feature enabled, it generates a tap-unique authentication message and crypto-secure URL.

This new technology offers increased security, data integrity and scalability while maintaining compatibility with existing systems. It also provides a high level of protection against relay attacks and has an automatic anti-tear mechanism for all file types.

The MIFARE DESFire EV1 chip has a capacity of 28 different files (called “applications”). Each application is a secured folder with a three-byte AID and one or two application keys assigned (APKs). Using an API the size of the file can be defined at the time of creation.

The MIFARE DESFire v2 is an enhanced version of the EV1. It has a memory size of 2K or 4K, and can hold a maximum of 28 applications with up to 8 desfire ev1 security keys. It meets global standards, including those on air interfaces and encryption methods, and anticipates future privacy protection requirements. Moreover, it can support MIFARE DESFire Plus credentials. This means that it can be used as a contactless key for a variety of applications, including access control and biometric identification, public transportation, cashless vending, ticketing and customer loyalty.

EV1 is a multi-application NFC smart card

The MIFARE DESFire EV1 chip provides excellent security performance and multi-application functionality for contactless smart cards. It uses a hardware cryptographic engine to encrypt transmission data. Its open concept provides room for future integration of alternate media. The card is based on the NFC standard and can support key fobs, mobile ticketing, smart paper tickets and IDs, as well as logical access and biometric ID systems. The chip is also compatible with most existing readers.

The DESFire EV1 card has good speed, memory capacity and performance, making it ideal for public transport schemes, access management and closed-loop micropayment applications. Its on-chip backup management system and mutual three pass authentication provide a high level of protection against security threats. It can hold up to 28 different applications and 32 files per application. It can also store an optional CMK for additional application keys.

This card has several advantages over previous generation chips, including longer read ranges and backward compatibility with MIFARE DESFire EV1. Institutions can purchase EV1 cards now and upgrade to EV2 when they become available from their system providers. However, it may be some time before EV2 is available in the market, so it makes sense to purchase a DESFire EV1 card now and use it until EV2 is ready for you.
