1. An apparatus comprising:
- a surface;
a non-data-encoding feature on the surface provided to serve as a beacon enabling optical discrimination of the apparatus in an infrared frequency band and identification of at least one of the orientation or pitch of the apparatus; and
a data-encoding feature on the surface provided to convey a data set associated with the apparatus in a visible frequency band, wherein the data-encoding feature is distinct from the non-data-encoding feature.

Abstract
In one implementation, a method of tracking assets includes obtaining a first image in a first optical domain, where the first optical domain is characterized by a first frequency range. The method also includes detecting a tracking apparatus (e.g., a tag) within the first image in the first optical domain, where a first feature of the tracking apparatus serves as a beacon enabling optical discrimination of the tracking apparatus in the first frequency range. The method further includes determining information associated with the tracking apparatus based on the arrangement of a second feature of the tracking apparatus provided to convey a data set associated with the tracking apparatus.

18. A non-transitory memory storing one or more programs, which, when executed by one or more processors of a device, cause the device to:
-
obtain a first image in a first optical domain, wherein the first optical domain is characterized by an infrared frequency range; detect a tracking apparatus within the first image in the first optical domain, wherein a non-data-encoding feature of the tracking apparatus serves as a beacon enabling optical discrimination of the tracking apparatus in the infrared frequency range and identification of at least one of the orientation or pitch of the apparatus; and obtaining a second image in a second optical domain, wherein the second optical domain is characterized by a visible frequency range; determine information associated with the tracking apparatus based on the arrangement of a data-encoding feature of the tracking apparatus within the second image in the second optical domain, wherein the data-encoding feature is distinct from the non-data-encoding feature.
