Control of an apparatus is provided according to determination of positioning of information pieces with radio frequency identification (RFID) tags. In embodiments, an apparatus may include one or more pieces, wherein each piece may be positionable in one or more piece positions of a region and may include a passive RFID tag that stores information relating to a characteristic of the piece. An arrangement of RFID antennas may be positioned proximal to the region, and a RFID reader may provide reads of the pieces near the RFID antennas. One or more processors may determine the piece positions of the one or more pieces from the reads and may provide control of the apparatus according to the one or more pieces and their piece positions.
