RFID systems gives the opportunity to have wide access control integrated with the monitoring of people and goods flow. System's scalability is one of the most important features in such systems as they enable large scale deployments. The concept of the proposed reader's architecture employs new RFID transceivers and microcontrollers, security algorithms which gives very high functionality at low price. Special treatment of system's...

Opis koncepcji zintegrowanego systemu RFID w połączeniu z innymi technologiami sensorów tworzących hybrydowy system RFID.

This paper presents various concepts of switching polarization in patch antenna dedicated for UHF RFID readers. Proposed designs allow for switching between linear and circular polarization. The first design does not require electronic switching as the polarization can be changed by choosing one of two available feeding terminals. Two remaining designs use PIN diode or FET SPDT switch.

Technologia RFID stanowi nie tylko technologię bliźniaczą w stosunku do kodów paskowych, ale posiada również dodatkowe cechy takie jak zdalna identyfikacja przy użyciu fal radiowych. Technologia ta staje się coraz bardziej dostępna i koszty jej wdrożenia są coraz mniejsze. W artykule przedstawiono wykorzystanie technologii RFID do ochrony sprzętu laboratoryjengo przed kradzieżą. Zawarto opis laboratorium wyposażonego w urządzenia...

The aim of the project is to design and create an electronic system, which can be used to protect laboratory equipment against theft. The main task of the system is to warn a person responsible for the facilities about any attempts made to steal equipment from a laboratory. In a case of an alarm situation, the system emits a sound signal. The concept of the anti-theft security system based on RFID was developed on the basis of...
