What Digital Logic does

Digital Logic (legal entity: Digital Logic RnD LTD; brand: D-Logic) is a privately held Serbian electronics manufacturer headquartered in Požarevac, with operating roots traceable to approximately 1970 as an electronics service and repair workshop. The company designs, develops, and manufactures its entire product portfolio in-house in Serbia, operating across four primary product families: (1) time-and-attendance (T&A) systems anchored by the AIS software platform (AIS Server, AIS Time WEB TnA, and TnA desktop) paired with proprietary contactless readers (AIS Base HD supporting up to 3,200 employees per unit, NFC 2DQR Reader, uFR Nano); (2) physical access control hardware including tripod turnstiles, full-height multi-arm barriers, electronic locker systems, and residential building access systems using NFC/MIFARE/2DQR credentialing; (3) ticketing systems for sports, recreation, cultural venues, and public transport with real-time sales monitoring; and (4) GPS/GPRS vehicle tracking modules and software for fleet operators, complemented by a hotel access and SOS system and an in-house plastic/NFC card production service.

The underlying technology is built on ISO 14443-compatible 13.56 MHz NFC and MIFARE smart-card standards, 2DQR barcode reading, and GPS/GPRS telemetry, with optional IP camera integration for anti-fraud verification (e.g., eliminating "buddy punching" in T&A). Products are differentiated by a bidirectional barrier mechanism, integrated 8-hour battery backup in the AIS Base HD reader, and autodetection shift logic in the TnA software, with hardware typically sold on a quote-based perpetual license and installation handled by Digital Logic's own professional services teams.

Digital Logic generates revenue primarily through one-time hardware sales and perpetual software licenses, with smaller recurring contributions from a subscription cloud application (AIS Time WEB TnA, offered with a 3-month free trial), system rentals, and after-sales installation, training, and maintenance services. The go-to-market is direct enterprise sales targeting small (≤200 employees), medium (≤512), and large (≤3,200) enterprises, plus government and public-sector buyers, with export channels reaching more than 60 countries. The customer base spans transportation (Arriva, Kavim, FAS-Fiat), municipal government, healthcare, education, manufacturing (Bambi), sports/recreation, and residential buildings, anchored by 200+ enterprise customers and a published reference list of 158+ organizations. The company is bootstrapped and founder-owned, with no disclosed external funding, M&A activity, or management transitions in the available data.
