RFID NFC Reader Writer - µFR Nano

ISO14443 Type A & B, ISO18092 Card Programmer

RFID NFC contactless reader/writer – µFR Nano is an advanced development tool based on NFC and RFID technology. It operates at a frequency of 13.56 MHz, compliant with ISO14443 A&B and ISO18092 standards.

We also provide plug-and-play apps that make µFR Nano an excellent choice for end-users, as well.

This small but powerful device is fully featured and fully NFC compatible. It is available with USB, UART (TTL), or RS232 connectivity options. Followed by a well-documented API, software SDK, cross-platform libraries, firmware upgrades, and excellent technical support, it’s the No 1 tool for any RFID NFC custom project development.

Hardware features

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 standards.

Both hardware and software support MIFARE®, NTAG21x, NTAG 4xx DNA, and JCOP family cards/tags.


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, tablets, Smartphones, Embedded systems, Raspberry Pi and other compatible Single Board Computers, Beagleboard, MIPS boards, PLCs, and Arduino.

Frequent firmware updates include new features, improvements, and bug fixes while preserving backward compatibility with the previous versions. 

Accordingly, the 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.

SDK and source code software examples

This RFID NFC reader comes with a fully-featured Software Development Kit with external libraries, examples with source codes, documentation about API references, communication protocol, and many useful software tools.
