Enjoy seamless logins and safeguard your data with the most advanced hardware security key today.
CRYPTNOX products are also available worldwide through our official Amazon stores.
With FIDO2 Card with MIFARE® DESFire®, you can now enjoy easy and secure authentication. It is the strongest form of protection against unauthorises access to your online accounts. Each time you want to access your account, all you need is the physical authentication device—the Cryptnox security key. This grants you passwordless authentication.
And now that Cryptnox FIDO2 Card can be encoded as an RFID MIFARE® DESFire® access badge, its functionality goes beyond online authentication. You can now use it as a smartcard or to facilitate access control to servers and facilities. With the Radio Frequency Identification (RFID) feature, the card can easily be identified by most access control readers. This delivers the next level of performance, enhanced security, multi-platform authentication and authorization.
Cryptnox FIDO2 Card with MIFARE® DESFire® technology is a security key based on the FIDO2 (CTAP2) & U2F (CTAP1) RFID MIFARE® DESFire® EV2 (Memory 4K) protocol. This means it has a smart card interface (contact and contactless/NFC), backed by FIDO2 standards.
The FIDO2 card offers a robust and convenient authentication solution for online platforms. It provides you with user-friendly security solutions in a wide range of environments, whether mobile or desktop.
Equipped with MIFARE® DESFire® EV2 (and 4K bytes of read/write memory), you can use the card for a variety of applications, including access control, transport management and payment solutions. The card also features a robust storage capacity with 4K memory, making it ideal for storing your personal data, cryptographic transaction keys and digital certificates securely.
Enjoy enhanced security against phishing and unauthorised access. Eliminate the inconvenience associated with passwords.
It features an advanced encryption system to secure your data and prevent common breach.
Our FIDO2 cards are compatible across various web-based platforms, whether you prefer USB-C or wireless NFC.
No need for software or complex configuration. Safeguard your login with a tap on NFC enabled device or use a smart card reader.
With MIFARE® DESFire® technology, the card is suited for applications, including public transportation, access management and many more.
With advanced encryption, the card ensures your data remains valid and accurate. Secure authentication prevents anyone from altering or changing your data.
You can purchase the FIDO2 card from our online store or Amazon. It is also available in respective Amazon stores in Germany, France, Italy, Belgium, Switzerland, Spain and other locations.
With a FIDO2 Card with MIFARE® DESFire® technology, you enjoy the best of both worlds, resulting in a secure and multi-functional solution ideal for various applications. Some benefits include:
The MIFARE DESFire access application and the FIDO2 authenticator share one secure element but never share data. Three mechanisms keep them apart:
The secure element is an NXP JCOP 4 P71 chip certified Common Criteria EAL 6+; the FIDO2 applet is FIDO Certified Level 1; the DESFire application is a licensed NXP implementation with no separate certification claimed. Losing the card therefore means revoking two credentials, the door credential and the FIDO2 registration, and neither reveals the other.
MIFARE® DESFire® technology powers contactless cards. It features secure memory RFID smart chips, resulting in superior performance and speed of transaction.
The card works with Windows, macOS and iOS. On Android it is supported for U2F/CTAP1 logins. Tap it to an NFC-capable phone, or use it with a USB card reader on a computer — on Windows the Cryptnox Click-to-Tap reader adds a virtual tap button, so the card never has to leave the slot.
Besides being equipped with FIDO2 (CTAP2) & U2F (CTAP1) RFID and MIFARE® DESFire® EV2 (Memory 4K), our FIDO 2 card features a Level 1 certification, and the secure chip comes with a Common Criteria EAL6+ certification. Both are independent, third-party certifications of the card and of its secure element.
1. Better security: Cryptnox FIDO2 card is a highly effective authentication method that protects you from cyber threats, including man-in-the-middle attacks, account takeovers and phishing. It utilizes key cryptography and possession factors.
2. Functional and Convenience: No need to worry about complicated passwords. FIDO2 gives you phishing-resistant two-factor sign-in wherever it is supported, and fully passwordless sign-in on the services that offer it, such as Microsoft Entra, Google and login.gov. This enhances security while lowering costs associated with service desks.
3. Easy to deploy: FIDO2 relies on open standards. It is known for its ease of integration into various systems and online platforms. For instance, you do not need a complex configuration or installation process to set up your Cryptnox security key.
4. Great for mobile authentication: For devices with NFC features (such as iPhones), you can easily authenticate your login by tapping your NFC reader.
You can check out our tutorial page and FIDO official website for more information.
We advise that you always have a backup method of authentication in a situation where you lose your FIDO 2 key. You can always get another FIDO key and authenticate it with online services to serve as a backup.
A lost card does not by itself give anyone access to your accounts. Each credential is unique to the service it was registered with, the card carries no personal identity information, and anyone who found it would still need your PIN.
You can also contact Cryptnox Support for any enquiries or issues.
FIDO 2 technology eliminates concerns about insecure logins and difficult-to-remember passwords. Presently, a large number of online platforms (including Bank of America and Google) now allow users to use FiDO 2 security keys to authenticate their login.
What’s best about FIDO2 cards such as Cryptnox is their ease of use. No complicated login process. All you need to do is tap the card to your device over NFC, or seat it in a USB card reader. On a Windows desktop the Cryptnox Click-to-Tap reader makes this markedly easier: when a service asks you to “tap your security key”, you press the reader’s Click-to-Tap virtual button instead of pulling the card out and reinserting it. The card never leaves the slot and the sign-in finishes in seconds. The virtual button works on Windows with Cryptnox FIDO2 cards; on macOS and Linux the same reader operates as a standard PC/SC contact reader for any ISO 7816 card. See the Click-to-Tap virtual button tutorial for the steps.
With FIDO2 technology, businesses and individuals can reap the benefits of enhanced security and authentication.
Cryptnox FIDO 2 cards are equipped with MIFARE® DESFire® technology, which helps streamline access management, enhance the user experience and lower the chances of security breaches occurring.
Our FIDO 2 cards can also serve as access control cards that can be tailored to your specific requirements. They can work as access cards for entry into secure facilities and multi-factor authenticators for your computers at the same time.
This will help you simply and seamlessly access security systems without the need for switching cards or devices.
The card operating system only delivers commands to the application a reader has selected, each application owns its own files and keys, and the secure element’s Java Card firewall and security domains prevent any applet from reading another’s memory. The FIDO2 private keys never leave the card and the DESFire keys are not readable by the FIDO2 applet.
Door access uses the building’s DESFire readers over the contactless interface. FIDO2 sign-in works over NFC with a phone or a USB contactless reader, and over the contact interface with a USB contact reader; on Windows the Cryptnox Click-to-Tap reader completes the user-presence check while the card stays in the slot.
