Abstract - Radio Frequency Identification (RFID) can be used as a technology for coupling the physical and the virtual world in ubiquitous computing environments. In this paper, it will be seen that RFID is also a very interesting option for building augmented real-world games. In this paper, the use of RFID technology is motivated for the development of board games. Then we will put some researches done in this domain which are done already by researchers. Then some localization techniques are discussed. Afterwards, the author's idea to incorporate RFID system for developing a chess board is discussed. RFID based Chess Board is an attempt to design and build a useful sensory chessboard. It takes a look at various proximity sensors and how they can be applied to detect chess pieces. The chessboard is connected to a microcontroller allowing play in training mode and competition mode.
Key Words - RFID, RFID tags, RFID readers, Localization, proximity sensors, key matrix, RFID game boards, Chess board
I. INTRODUCTION
RFID applications are the keystone of the emerging 'Internet of Things'; that will connect objects and places. They will create many new opportunities for business and society, but first there are a number of political and social issues to be considered. RFID was first used in the late 1960's, but it has only become more widespread with advances in technology.
A. How RFID works?
RFID is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it.
B. Components of RFID System:
1. RFID tag (transponder):
The identification device attached to the tracked item. A tag is programmed with a unique identification and descriptive information that can be read at distances ranging from...
