Digital Logic Ltd. is one of the first companies in the world to implement digital signing solution with contactless RFID cards.
We expect that old systems which still use contact cards will soon become a thing of the past.
A lot of effort is invested in Research, Development, and implementation of ECDSA and RSA algorithms into the firmware of our uFR Series readers.
Our goal was to adopt new cryptographic feature set without compromising basic reader functionalities and a rich set of existing API calls, while preserving the backward compatibility with earlier versions.
The highlight is to keep security at the highest possible level. Secret keys are always transported and stored securely at the hardware layer.
We are constantly improving and developing new features and possibilities, adding support for new card types and cryptographic algorithms, especially in the field of ECC curves.
To provide a good demonstration of possibilities, we developed free software called “μFR Signer”, which fully compatible with our μFR Series readers.
“μFR Signer” software supports both RSA and ECDSA cryptographic algorithms for digitally signing files.
The software is intended to be used with our μFR Series of NFC devices: Nano, Classic, Classic CS and Advance.
μFR Signer works with all cards which support RSA and ECDSA.
There are almost endless possibilities, from regular document signing on a daily basis to use of advanced techniques to sign sensitive data like confidential documents or financial transactions.
We see ECDSA signing with RFID/NFC cards as a future possibility for use with any of nowadays popular crypto-currencies, like Bitcoin and other altcoins.
Leider gibt es für diesen Aussteller kein deutsches Firmenprofil.
Digital Logic Ltd. is a Serbian company, established as an electronics repair shop in 1966, , transformed into production company in October 2000. It is engaged in research, development, production, implementation, maintenance and servicing of electronic devices based on NFC RFID technology and accompanying Software Development Kits (SDK).
Digital Logic’s Research and Development Department, with its Hardware and Software engineering teams, created an entire series of NFC RFID readers and writers of contactless cards. These devices, also available as OEM solutions, were implemented by software development companies in over 60 countries.
Digital Logic NFC RFID readers’ 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® family (MIFARE Mini®, MIFARE Classic® 1K, MIFARE Classic® 4K, MIFARE Ultralight®, MIFARE DESFire® EV1 and MIFARE Plus®) RF identification protocols are supported.
Company’s software engineers created an entire package of solutions compiled into detailed Software Development Kit, which is available for free and is being constantly upgraded. 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.
All examples are written for all major developing platforms and languages, like:
Java (and Java Applet example),
C++ Borland Builder,
Microsoft® Visual .NET family: C++, C#, VB
Other programming languages examples can be obtained on customer demand.
In a past few years, company’s Research and Development department delivered to users several solutions that are quite unique, speaking in global terms, receiving awards and acclamations. Competing with the companies from the Far East, Digital Logic is offering adaptable, high end solutions to customer’s demands, and providing quality support around the clock, for users worldwide. Customer support, combined with software upgrades that are beingcontinuously developed, are ensuring its clients that service doesn’t end up with the purchase.
The list of company solutions is long and some of the systems are uFR Classic NFC RFID Reader/Writer, uFR Nano NFC RFID Reader/Writer, Base HD USB NFC RFID reader, Android Power Bridge (APB), DL533X (OEM) contactless reader, DL NFC 2DQR Reader.
Company products found their application in the fields of
NFC RFID programming tools containing devices and Software Development Kits (SDK), wrote by company's own team of IT engineers and sold through e-shop and with excellent reception among IT professionals around the world.
Transport (Bus ticketing, Electronic fare collection, GPS satellite tracking).
- Access control (Time and Attendance system, turnstiles, System for controlled access to Concert halls, Sport venues, Water parks and pools).
Digital Logic‘s engineers are constantly upgrading products and developing new solutions, proving that innovative thinking is the only key to success.
