Who is it for?

µFR Nano RFID NFC Reader/Writer is primarily suitable for development companies and individuals (professionals and hobbyists) for further applications and turnkey solutions development. Hence, it comes with a fully-featured Software Development Kit, including firmware, libraries, source code examples, and documentation for various platforms, operating systems, and development environments. We launch upgrades frequently (including firmware, libraries, and API). All updates are available to download at our official website for FREE.
In addition to the above facts, our free, extensive and fast support makes RFID NFC Reader Writer – µFR Nano a high place in this industry sector.


The RF communication of this NFC RFID reader writer is based on its highly integrated robust NXP IC interface. Therefore, the device operates on HF 13.56 MHz and successfully communicates with cards, labels, wristbands, and tags of ISO/IEC 14443 A, ISO/IEC 14443 B, and ISO/IEC 18092 standard.

As a result of its outstanding modulation and demodulation concepts and many integrated 13.56 MHz contactless communication protocols, the implementation of this device is simple and reliable for any RFID NFC solution developer.

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. 


The OEM board is available in three versions:

  • USB – with standard micro-USB connector
  • UART TTL – with the 5-pin male header connector
  • RS-232 – via an adapter with a DB9 connector.


Digital Logic’s proprietary interoperable firmware runs on all µFR series hardware based on the MCU platform. The reader and host establish communication through the fast FTDI chip.

Basically, at the communication level, the device uses a unique proprietary Digital Logic communication protocol.
The µFR series 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.
