A data control device adapted for controlling data in connection with an optical or magnetic detection device is disclosed. The main body of a paper structure of predetermined dimensions has a plurality of horizontal rows extending across a plurality of vertical columns formed by pairs of separated contrast stripes. One vertical column provides timing or reference signals for the data contained in the horizontal rows. Data is entered by connecting at least two vertical stripes in a horizontal row with a connecting indicia. The space between the stripes may have numbered indicia means for indicating the value entered. In one embodiment, portions of the control device are provided with detection means for absorbing energy of an incident light source, thus, providing means for optical detection. The control device is particularly adaptable for use in restaurants and hotels and similar business where bill totalization is required.
