1. A transparent tag comprising:
- a first layer implementing a base mirror component that reflects at least infrared light wavelengths;
a second layer implementing a matrix component, the second layer being situated on one side of the first layer and having one or more portions that absorb at least infrared wavelengths of light, the portions that absorb infrared wavelengths of light and other portions through which infrared wavelengths of light are reflected encoding data; and
a third layer implementing a filter component that absorbs one or more particular wavelengths of light, the third layer being situated on an additional side of the first layer that is opposite the one side.

Abstract
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.

12. A transparent tag comprising:
-
a base mirror component implemented in a first layer that reflects at least infrared light wavelengths, the first layer comprising a polymer substrate for a dielectric optical stack on one side of the polymer substrate, and the polymer substrate including one or more dyes that absorb at least near infrared wavelengths of light and red wavelengths of light; a matrix component implemented in a second layer, the second layer comprising ink printed on an additional side of the polymer substrate that is opposite the dielectric optical stack and having one or more portions that absorb at least infrared wavelengths of light, the portions that absorb infrared wavelengths of light and other portions through which infrared wavelengths of light are reflected encoding data; and a filter component implemented in the first layer or in a third layer that is situated on the one side of the polymer substrate, the filter component being a blanket filter that absorbs at least near infrared wavelengths of light.
