Abstract
A credential substrate rotator includes a substrate support, a substrate feeder and a substrate sensor. The substrate support is configured to support a substrate in a substrate support plane and rotate about a central axis. The substrate feeder is configured to feed a substrate along the substrate support plane. The substrate sensor includes a substrate position indicator that is aligned with the central axis and has first and second positions. The first position indicates an absence of a substrate from a predetermined location of the substrate support. The second position indicates a presence of a substrate in the predetermined location of the substrate support. Also disclosed, is a credential substrate processing module that includes a credential substrate rotator, a first data encoder and a module controller. The credential substrate rotator includes a substrate support configured to support a substrate in a substrate support plane and rotate about a central axis, and a substrate feeder. The first data encoder is configured to encode data to a substrate presented by the substrate rotator.
