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.
