uFR Series - Nano model by Digital Logic

µFR NANO NFC RFID reader and writer

µFR Nano is the latest model in Digital Logic’s µFR Series of NFC RFID readers writers.
It is NFC Forum & RFID compatible contactless reader/writer which successfully implements ISO14443 A & B and ISO18092 standards on HF working frequency of 13.56 MHz.
This device is genuine Digital Logic product, 100% designed, produced and programmed at company premises located in Serbia, Europe.
All models of µFR Series are using the same SDK API and are totally compatible and interoperable in common set of functions.


Device is primarily intended for developing companies and individuals (professionals and hobbyist) for further application and turnkey solutions development. For that reason it comes with fully featured SDK package, which includes firmware, libraries, software examples and documentation for various platforms, operating systems and developing environments. Regular SDK upgrades (including firmware, libraries and API) are launched often and can be obtained by company’s website for FREE. All products has extended „Three year” warranty.
All mentioned facts combined with free extensive and fast responsive support give this product an outstanding position in this industry sector.

Reader’s RF communication is based on NXP’s powerful, highly integrated reader IC for contactless communication at 13.56 MHz, which supports all protocol layers of the ISO/IEC 14443 A, ISO/IEC 14443 B and ISO/IEC 18092 communication standards.
It utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz.
All variants of the Mifare® cards family (MIFARE Mini, MIFARE 1K, MIFARE 4K, MIFARE Ultralight, MIFARE DESFire EV1 and MIFARE Plus) RF identification protocols are supported. Additionally, NFC Forum specification for „Type 2 Tag” is supported, which adds NTAG2xx chip family to above list.
Reader has possibility to support all NFC Forum Tag Types, but currently implemented is Type 2. Since DESFire can be used as NFC Tag type 4, it will be added soon as capability in firmware. Additional features like other Tag types (1 and 3) and Pear 2 Pear functionality are on R&D roadmap.
Bottom line is that reader’s hardware is fully compliant with NFC Forum specification.
Reader has built-in anti-collision mechanism for detecting multiple cards at time.
Built-in well-tuned antenna provides proximity operating distance up to 80 mm (depending on card’s antenna geometry) and contactless communication speed at higher baud rates (up to 424 kBd).
Device also has built in Crypto1® algorithm and non-volatile internal key memory storage for better security.
Reader can also act as a serial interface device using FTDI’s Virtual COM port (VCP) drivers.
Audible (speaker) and 2 LEDs visible indicators are built in and absolutely user controllable.


OEM board comes in two versions: with standard micro-USB connector or with RS232 pins on TTL levels, with additional cable device for true RS232 voltage levels.


Since hardware is based on MCU platform, it runs on company developed custom firmware. Communication between host and reader is provided through high speed direct access FTDI chip features.
At core communication level device uses company developed, proprietary communication protocol, which is well documented in SDK API reference.
Firmware has a lot of built-in complex functions which can be called via libraries provided in SDK API. Most of functions are written to make „life easier”, like:
  • Multiple readers on same host support
  • Whole set of commands for Mifare card manipulation according to manufacturer’s specification
  • Different addressing schemes (Block, BlockInSector)
  • Key storage manipulation (one way, write only, no reading of stored keys)
  • Different key applying modes (by index or scheme)
  • Value block manipulation
  • Treating whole card memory structure as linear space (very convenient for Mifare Classic cards)
  • NFC tags manipulation, NDEF format parsing in firmware
  • AES128 “on fly” hardware encryption built-in, which is the most important when working with complex DESFire security keys and cards
  • AES128 encryption of files and keys in DESFire cards
  • Asynchronous sending of card UID from reader to host COM port when card is present; feature is user programmable and many more…
Main point about firmware is that all firmware functions can be called via communication protocol, too.
That fact moves usage of this device into other dimension, meaning that this reader can be used on almost any platform which has serial interface, by simply using communication protocol. So it can be freely used on PC, tablet, smart phone, embedded systems, Raspberry Pi, Beagle Board, MIPS boards, PLCs and other platforms.
When using OEM RS232 board, device can be connected on any platform which has “real” serial interface, which is seen as a great benefi t.Firmware is regularly updated with new versions which include new features, improvements and bug-fi xes, while preserving backward compatibility with older versions.
That means your code is safe, there is no need for changes when new fi rmware comes out. All fi rmware upgrades are totally FREE and can be obtained through download section of company’s website.

 Software Development Kit (SDK) package

Reader comes with fully featured SDK which consist of external libraries, software examples with source codes, documentation about API reference and communication protocol and some useful software tools.
Libraries are cross-compiled for various platforms and regularly supported are Windows x86/x64, Linux x86/x64, Mac OSX x64, ARM and ARM HF. Other platforms can be supported as custom release, on customers demand, depending on existence of project or partnership relation.
Software examples are divided in three stages according to complexity, with some new additions of NFC examples.

 All examples are written for all major developing platforms and languages, like:

  • Java (and Java Applet example),
  • JavaScript (unique feature, convenient for PHP usage),
  • Lazarus,
  • Borland Delphi,
  • C++ Borland Builder,
  • Microsoft® Visual .NET family: C++, C#, VB
Other programming languages examples can be obtained on customer demand, depending on existence of project or partnership relation.

 Software package includes set of very useful applications intended for everyday use, like:

  • Application for programming and manipulation of NFC compliant cards like NTAG and Mifare Ultralight, with source code included.
  • Android NFC phone App - Android NFC phone Application for Mifare card reading. Write a card with uFR, read it with NFC phone!
  • Card formatter - application for card/tag formatting and programming
  • µFR2FileSystem - keyboard simulation, card data reading, card data parsing into several formats and sending data to MySQL database via HTTP.
  • Application for NTAG and Mifare Ultralight card programming and manipulation.
  • Application for creating and writing common NDEF messages into NFC tags and cards
  • Reader Keys application – for easy manipulation of keys stored in reader
  • Application for managing of DESFire cards
Documentation contains fully explained API reference and communication protocol reference with real “hands-on” byte level examples for implementing communication protocol. However, API is much more comfortable and recommended way of implementation. Where not possible, implementation of communication protocol is very good alternative.
All libraries, software examples, tools and documents are regularly updated. They are totally FREE and can be obtained through download section of company’s website.
Our support team always provides quick response, usually not more than 24 hours, which also depends of complexity and question itself.
We can also provide custom solutions based on each customer's needs, so please free to contact us for any question or further help regarding your projects and implementation.
