Key fobs with Mifare Desfire EV3 chips
(Product ID: 3643)

RFID key fobs with the Desfire EV3 chip are advanced contactless key fobs from the Mifare DESFire® family, used for various applications such as access control, payment systems, and user identification.

These key fobs operate at a frequency of 13.56 MHz and follow the ISO/IEC 14443-4A/B and NFC Type 4 protocol.

MIFARE DESFire® EV3 chips are compatible with previous versions of DESFire® EV2 and EV1 chips - which are used in various applications worldwide.

Desfire type chips contain a 7-byte long unique ID number (UID) and storage capacity that can be 2 kB, 4 kB, or 8 kB of data.

We can also print your logo or number the RFID key fobs and it is also possible to order key fobs with housings in different colors.

INFO

Mifare DESFire® EV3 RFID key fobs are most commonly used in advanced door opening systems, and user identification in applications requiring a higher level of security.

MIFARE DESFire EV3 RFID key fobs typically have a teardrop-shaped housing made of plastic material (ABS) and measure 40 x 32 x 3.5 mm. The key fob also includes a metal ring, making it easy to attach to keys or other keychains.

Options for Printing and Personalization

Key fobs from stock come without numbers or other printed elements, but if you need key fob printing, let us know, and we will send you an offer.

You can also order custom RFID key fobs with housings in different colors or shapes. We can print your company's logo, serial number, or chip ID code on the key fobs.

Since the chip ID code can be read in more than 50 different ways, we take special care to print the code in the correct format. Many NFC devices (including NFC phones and tablets) read the chip ID in a 14-digit hexadecimal number (known as the 14 HEX Reverse Byte format).

MIFARE DESFire® chips are manufactured by the renowned chip manufacturer NXP Semiconductors and are the most popular NFC type 4 chips (chips for secure transactions).

MIFARE DESFire EV3 is the successor to MIFARE DESFire EV2 and offers even more advanced hardware and software implementation.

MIFARE DESFire EV3 includes all known commands and functions from the MIFARE DESFire EV2 system and adds some new features, such as a transaction timer and secure dynamic messaging.

The technical comparison and compatibility between DESFire EV1, EV2, and EV3 versions are detailed in the document: https://www.nxp.com/docs/en/application-note/AN12752.pdf
