Electronics Service Zvonko

Elektronics Service "Zvonko" was founded on November 16th 1966. Headquarters Services was in Aleksandrovac until '80s when moved to Pozarevac where still operates.

The service had three workers which were engaged in service of TV, radio, music amplifiers and other electronic devices. Special attention should be paid to servicing of musical instruments based on digital electronics (accordions and organs) in which area Electronics Service Zvonko was the first and the only service in former Yugoslavia.

In the early nineties, ES "Zvonko" signed the contract with "Telekom Serbia" for servicing Ericsson AXE10 digital telephone exchanges on many business units (Pozarevac, Belgrade, Novi Sad, Pirot, Batajnica, Surcin). This collaboration lasted until 2007. year.

On the other side, in 2000. the other company - D-Logic was founded with an idea to develop identification systems. An ambitious five-member team, funds for investment in the development of this project collected from the proceeds realized by performing the GSM services (service and manufacturing sofrware for mobile phones). For these reasons D-Logic operations were already divided into two parts:

1) Maintenance and development of service software for GSM phones and

2) The development of autonomous identification system.

In the framework of software for mobile phone devices, D-Logic soon develops unique software solutions with focus on Alcatel mobile phones, engage two servers and perform online software repair of GSM device.

After more than three years after its foundation, the first phase of identification of autonomous system was completed and the first exchange unit with the readers was implemented (users: Dunav Insurance, Ministry of Interior, restaurant Ruski car). This system has already provided protection against the eventual ID cards cloning .

In 2006th ES Zvonko and the D-logic were integrated to form the current business structure..
