The history of RFID
TLDR
This RFID system uses the principle of modulated backscatter where it can transfer the data from the tag to the reader and changes the loading on the tag antenna in a coded manner corresponding to the stored data.Abstract:
Radio frequency identification (RFID) is an integral part of our life, which increases productivity and convenience. It is the term coined for short-range radio technology used to communicate mainly digital information between a stationary location and a movable object or between movable objects. This RFID system uses the principle of modulated backscatter where it can transfer the data from the tag to the reader. The tag generally reads its internal memory of stored data and changes the loading on the tag antenna in a coded manner corresponding to the stored data. RFID is a technology, which spans systems engineering, software development, encryption etc., and thus there are many engineers involved in the development and application of RFID and at present the shortage of technical and business people trained in RFID is hampering the growth of the industry.read more

Short-range radio-telemetry for electronic identification, using modulated RF backscatter
TL;DR: In this article, an electronic identification system using modulated backscatter from an RF beam-powered tag is described, where a subcarrier is used in the return signal format to allow separation from the background clutter and to allow use of a novel method to avoid RF phase problems.
