Transparent tags with encoded data include both a base mirror component and a matrix component, and may optionally include a filter component. These components are combined to achieve a system having a tag that absorbs infrared light in particular portions and reflects infrared light in other portions, presenting a pattern which encodes the data included in the tag to sensors of a display panel. This combination of components also reduces near infrared and/or red ambient light that can be sensed by the sensor in the display panel, reducing interference from such ambient light when identifying the pattern while enabling the tag to be substantially visibly transparent to a user. |
