## Background
FIELD OF THE INVENTION
The present invention generally relates to a method and a system for object identification, and more particularly relates to a method and a system for remotely interacting with items in an electrical field affected environment.
DESCRIPTION OF RELATED ART
Internet now is being used with other technologies to meet the requirements of humans. One such field is known as Internet of Things (IOT). The Internet of things, also known as the Internet of objects, refers to the networked interconnection of everyday objects. It is described as a self-configuring wireless network of sensors whose purpose would be to interconnect all things. The concept is attributed to the former Auto-ID Center, founded in 1999, based at the time at the Massachusetts Institute of Technology (MIT).
Various systems operate on IOT to identify the items. Such systems are equipped with additional processing units which need power supply, interfaces, sensors, actors and one or more wireless transceivers such as Wi-Fi, Bluetooth etc. These systems use Radio-Frequency waves for communication with the computing devices.
Radio-frequency identification (RFID) is a technology that uses communication via radio waves to exchange data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking. Some tags can be read from several meters away and beyond the line of sight of the reader. The application of bulk reading enables an almost parallel reading of tags.
However, it is proven that electromagnetic microwaves are harmful for human tissue and is likely that the use of such radio frequencies can be restricted for the sake of health of humans. Battery operated small devices often use button cells for providing the electrical energy. It is known that such batteries are dangerous for the environment and unsafe in uses. Therefore, there is a need of a method and a system operating on electrical field for remotely interacting to provide condition and position of the items. Further, the method and the system should provide power without the use of batteries.
