Who is it for?

µFR Classic RFID NFC reader 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 Classic to an outstanding position in this industry sector.

Hardware

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 to 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),
• 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.

This RFID device also has a built-in Crypto1® algorithm and secure non-volatile internal key memory storage for better security. Communication with the host is provided by using the USB 2.0 Full Speed compatible interface. Data transfer rates are limited from 9600 baud to 1 Mbaud, for integrity and security reasons. This NFC RFID Reader can also act as a serial interface device using FTDI’s Virtual COM port (VCP) drivers.

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 global trends. 

Firmware

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 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.

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 GitLab repository.

Downloads: API Documentation, µFR COM Protocol, Software source code examples with SDK

The documentation contains a detailed explanation of API and communication protocol reference with actual byte-level examples for communication protocol implementation. Our API provides a very comfortable way of implementation, and we highly recommend it. When API implementation is not possible, a communication protocol is a very good alternative. We provide regular updates for all libraries, firmware, examples, tools, and documents. Updates are FREE and are available for download from the official Digital Logic GitLab repository. 

Our support team always provides prompt responses. Depending on the inquiry complexity, you can expect an answer in no more than 24 hours.
