Followed by a well-documented API, software SDK, cross-platform libraries, firmware upgrades, and excellent technical support, it’s a No 1 tool for any RFID NFC custom project development.

In addition to the final product in an attractively designed and customizable case, µFR Nano RFID NFC reader/writer is also available as an OEM NFC module with a connector of the customers’ choice.

Who is it for?

µFR Nano RFID NFC Reader/Writer is primarily intended for development companies and individuals (professionals and hobbyists) for further applications and turnkey solutions development. For this reason, 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 available to download at our official website for FREE.

In addition to the facts mentioned above, our free, extensive, and fast-responsive support brings RFID NFC Reader Writer – µFR Nano to an outstanding position in this industry sector.


This RFID NFC readers’ RF communication is based on its robust, highly integrated NXP IC interface. 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.

With outstanding modulation and demodulation concepts, and many integrated 13.56 MHz contactless communication protocols, this device implementation becomes reliable and simple for every RFID NFC solution developer.

Both hardware and software, are fully developed, tested, 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 proprietary interoperable firmware runs on all MCU platform-based µFR Series hardware. The reader and the host establish communication through the high-speed FTDI chip direct access.

At the core, on the communication level, the device uses a Digital Logic unique proprietary communication protocol

µFR Series firmware contains many complex built-in functions that can be called via libraries explained in API docs.

Most of the functions are developed to make „ life easier” for developers and integrators by decreasing their development time, such as: 

  • 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.

The μFR Firmware key feature is the ability to call all its functions using our communication protocol.

Therefore, the μFR device implementation is possible on almost any platform with a serial interface by using the communication protocol.

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 preserving backward compatibility with the previous versions. 

Accordingly, project code and developed software are safe, so there is no need for any changes after a firmware upgrade.

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

Registered International Airmail - Serbian Post service. The average delivery time for registered international airmail is 15-30 working days.

DHL Express - Expedited international shipping service. The average delivery time for DHL Express is 3-7 business days.

All other seller-buyer relationships not defined in this ad are covered by our Shipping Policy.


When the order is shipped as registered international airmail, the parcel gets an international tracking number in a format consisting of 2 letters, followed by 5-9 numbers and ending with 2 letters.

Due to the different standards of the tracking number in some countries, the initial tracking number may be replaced with a new one when the package arrives in that country.

Changing the tracking number is common for U.S. shipping addresses due to the USPS standard for tracking mail numbers. If you have trouble tracking a package after it arrives in the U.S., we recommend that you contact your local USPS mail office and request a new tracking number.

* Business days include days from Monday to Friday. Saturday and Sunday are considered weekend days.
