RFID (English Radio Frequency Identification, RFID) - a method for automatic identification of objects, which means radio is read from or write data testking 70-681 stored in the so-called, Transponders or RFID-tags. Any RFID-system consists of a reading device (reader, reader or interrogator) and transponder (also known as RFID-tag, also sometimes uses the term RFID-tag). Most of the RFID-tag consists of two parts. The first is an integrated testking 70-433 circuit (IC) for storing and processing information, modulating and demodulation of radio frequency (RF) signal and some other functions. Second - antenna for signal reception and transmission.Introduction of RFID-tags in everyday life associated with a number of problems. For example, consumers who do not have readers may not always detect the tags attached to goods during production and packaging and get rid testking 1Y0-A17 of them. Although the sale, as a rule, such tags are destroyed, the very fact of their presence causes concern for human rights and religious organizationstestking 70-450 Already known applications RFID (contactless smart card testking 70-293 systems, access control and payment systems) get more popular with the testking 642-072 development of Internet services. History of testking PMI-002 RFID tags In 1946, Lev Sergeyevich Theremin invented for Soviet spy testking HP0-P14 devices, testking 70-433 which allowed the cast audio information to a random radio waves. Sound causes vibration diaphragm which slightly change the shape of the cavity by modulating the reflected radio frequency waves. And although the device was a passive transmitter (so-called. "Bug"), this invention is referred to the first predecessor RFID-technology. ------------------------------ testking 1z0-533 l testking 650-568 l testking 70-270 l testking 640-864 l testking HP0-Y30 l testking 642-262 lk testking 1z0-451 l testking 70-291 l testking 646-985 .
