Designed with IT companies and individual developers in mind, µFR Zero NFC devices serve as professional tools for those involved in RFID NFC solution development. Featuring free NFC SDK with source code examples, cross-platform libraries, upgradeable firmware, and comprehensive API and communication protocol, the µFR Zero NFC devices ensure seamless NFC software integration.

The availability of plug-and-play applications effectively expands the user base of the µFR Zero NFC readers to end-users as well.

ufr zero series modular nfc readers

µFR Zero NFC devices are available with USB CCID, UART (TTL), or RS232 connectivity options. They are fully NFC compliant and feature Dynamic Power Control and Low Power Card Detection, which ensure the best possible card reading distance and functionality even while in Low Power mode.

The addition of well-documented API, software SDK, cross-platform libraries, firmware upgrades, and excellent technical support, makes µFR Zero devices exemplary tools for any RFID NFC project development.

Thanks to their modular design, the functionality of the µFR Zero NFC readers can be further expanded by stacking additional modules. Available modules include Access Control with integrated solid-state relays, SAM card slots, RGB displays, OLED displays, and the PIN pad. Custom development of µFR Zero modules is also possible upon customer request.

Hardware

NFC RFID readers’ RF communication is based on its robust, highly integrated PN7462 NXP IC interface. The uFR Zero devices operate on HF 13.56 MHz and communicate with cards, labels, wristbands, and ISO/IEC 15693, ISO/IEC 14443 A, and ISO/IEC 14443 B tags standard. With outstanding modulation and demodulation concepts, and many integrated 13.56 MHz contactless communication protocols, device implementation becomes reliable and simple for every RFID NFC solution developer.

Enhanced Security

One of the significant upgrades compared to the previous generation of devices is the introduction of a secure element with an integrated cryptographic co-processor and accelerator. It integrates ECDH (Elliptic Curve Diffie Hellman) security protocol along with ECDSA (EllipticCurve Digital Signature Algorithm). Apart from secure key storage, this cryptographic accelerator provides secure and quick authentication in a wide range of applications such as

Add-ons and upgrades

Thanks to its modular design, the functionality of the μFR Zero Series can be further expanded by adding various modules. Available modules include Access Control with integrated solid state relays, RGB LEDs, OLED displays, PIN pad, Wiegand interface, RS485 interface, SAM card slots, RTC (Real-Time Clock), and more. Custom development of μFR Zero modules is also possible upon customer request.

Supported technologies

Both hardware and software have been fully featured and successfully implemented with MIFARE®, NTAG21x, NTAG 4xx DNA, and JCOP family cards/tags:

  • MIFARE Mini®,
  • MIFARE Classic® (1K, 4K, EV1),
  • MIFARE Ultralight®,
  • MIFARE Ultralight C®,
  • MIFARE Plus® (2K, 4K, S, X, EV1),
  • MIFARE DESFire® (Light, 2K, 4K, 8K, EV1, EV2),
  • NXP NTAG® 21x (210, 213, 215, 216, Tag Tamper),
  • NXP NTAG® 4xx DNA (413, 424),
  • NXP JCOP® Java Card (J3A040, J3A081, J3H145, JC30M48CR).

Besides, this tool supports all other tags compatible with the listed above.

Even though the supported technologies list is already wide, our development team constantly works on product improvements and upgrades, staying in line with this technology’s global trends. 

Connectivity options

The OEM board is available in three versions:

  • USB CCID
  • UART TT
  • RS-232 

ALL µFR ZERO NFC READERS ARE ALSO AVAILABLE AS OEM NFC MODULES.

Firmware

Digital Logic proprietary interoperable firmware runs on all MCU platform-based µFR Series hardware. The reader and the host establish communication directly via the PN7462 CCID USB stack.

Basically, at the communication level, the device uses a unique proprietary Digital Logic communication protocol.
The µFR firmware contains many complex built-in functions available for calling via libraries explained in the API docs.

Finally, many functions implementation examples have been developed to make life easier for developers and integrators by reducing development time.
For instance, the following projects:

  • Support for multiple RFID NFC readers on a single host.
  • The whole set of commands for MIFARE Classic® manipulation according to the manufacturer’s specification
  • Various addressing schemes (Block, BlockInSector)
  • The key storage handling(one way, write only, no reading of stored keys)
  • Various key applying modes (by index or scheme)
  • Value block manipulation
  • Using the entire memory structure as linear space ( convenient for most card types)
  • NFC tags handling, NDEF format parsing in firmware
  • AES128 “on the fly” built-in hardware encryption, which is extremely important for working with complex DESFire security keys
  • AES128 encryption of files and keys in DESFire cards
  • MIFARE Plus support
  • MIFARE Ultralight C support
  • APDU command structure support, where applicable (ISO 14443-4 layer)
  • Asynchronous UID sending from reader to host COM port when a card is present – the feature is user-programmable.

Specifically, the μFR Firmware key feature is the ability to call all its functions using our communication protocol.
For this reason, it is possible to implement the μFR device on almost any platform with a serial interface.

Supported platforms include:

  • PC
  • Tablet
  • Smartphone
  • Embedded systems
  • Raspberry Pi and other compatible Single Board Computers
  • BeagleBoard 
  • MIPS boards
  • PLCs
  • Arduino.

Frequent firmware updates include new features, improvements, and bug fixes while maintaining compatibility with previous versions.
Accordingly, the project code and developed software are secure, so there is no need to make any changes after the firmware upgrade.

All firmware updates and upgrades are FREE and available at the Digital Logic official GitLab repository.
