Análise de interferências em sistemas RFID HF: aplicação de um ambiente de cassino.

Abstract

In this report, an overview of RFID systems is presented, specially the characteristics of the Gaming application, a technology that has recently received attention due to its security and convenience. A review of the system properties, literature, and basic theory of RFID and Electromagnetic Interference is presented, followed by an explanation of the circuit developed to measure the noise read by a reader’s antenna and the techniques utilized to reduce this interference. And to conclude a brief list of requirements is presented for the research of new partners using the UHF RFID, followed by test results of standard tags in near-field mode for the gaming application.
