Digital Logic LTD

Digital Logic LTD started as electronics service back in 1966. in Serbian city of Aleksandrovac. In the 80's and it has moved to city of Požarevac - where it still operates.

In its humble beginnings the Electronics service "Zvonko" had only three employees who were engaged in repairing TVs, radio devices, musical amplifiers and other electronic devices. Also, service was engaged in maintenance of musical instruments based on digital electronics - in this area, Electronics service Zvonko was the first and only in the former Yugoslavia.

Constantly expanding area of activity, in the early 90's Electronics Service Zvonko contracted with "Telekom Serbia" regarding service of telephone exchanges Ericsson AXE10 on a sveral locations (Požarevac, Belgrade, Novi Sad, Pirot, Batajnica and Surčin). This collaboration lasted until year of 2007.

At the same time, the service was among the first in the country engaged in service of GSM devices and developing software for mobile phones. As part of the software development for mobile phone devices, company quickly developed unique software solutions with a focus on Alcatel production program. Due to the volume of work and growing need to exchange data with customers all over the world, GSM system at that time constantly engaged two computer servers. That was beginning of the IT sector which was constantly growing in the future.

Experiences and ideas generated while working with GSM technologies and supporting IT infrastructure, served as the basis for the establishing of a separate company and brand D-Logic - officially launched at year of 2000. It is also the moment in which the entire company began the transition from service-oriented to a system that integrates the entire production process, from design and development to production and implementation of the final product.

Initially, D-Logic brand was primarily based on the development and production of the autonomous identification systems (AIS) which were developed by ambitious five-member team. This production created the basis for the current D-Logic systems with innovative solutions unique in the world. AIS systems were one of the first identification systems on the market which provided protection from cloning of identification cards, as well as many other unique solutions which nowadays make them distinctive in the market.

At the year of 2006. Electronics Service Zvonko and D-Logic merged and formed the business structure named SR "Electronics service Zvonko".

The requirements of business have caused the change of companies legal form at the end of year 2013. when it grew into LTD company named "Digital Logic". Today company operates continuously employing nearly 40 employees. The area of its business operation is divided into five main sections:

  • Design, manufacture and maintenance of the autonomous identification systems (AIS) and Access Control Systems.
  • Design, manufacture and maintenance of Fleet Management Systems which enable the monitoring of vehicle telemetry data, such as geographical location (GPS), engine RPM, temperature, fuel level, and other important parameters.
  • Design, manufacture and maintenance of Ticketing systems, which among other things provide electronic ticket payment systems for companies dealing with transport.
  • Development of new, unique solutions for electronics industry, which besides improving the existing equipment often results in development of entirely new devices and business activities related to them.

The future of the company as well as its growth are based on innovative solutions and constantly expanding development and manufacturing programs and successful cooperation with a vast base of domestic and foreign clients.




The list of D-Logic solutions is wide and some of the systems are Total Wireless Reader, uFR Reader/Writer, BusLogic Ticketing System, AIS Start System, Base System, Industrial Displays, Fleet Management, Industrial process control systems, Printing plastic cards and so on.

This system is unique for its Real Time event monitoring without any wires and it was rewarded in the field of modern technology with Special Recognition: "Step Into The Future" at the 56th International Fair of Technique and Technical Achievements in Belgrade.


The next step in the future D-Logic sees in the joining uFR and TWR project and providing a new solution for various RFID Real-Time Systems development – TWR SDK. This product will have all the best features of its predecessor – complete source development support as seen with uFR software and also the wireless hardware communication with long life time which was developed for TWR. TWR SDK is now ready to be lunched and provide great possibilities to many system developers and integrators.
