Paperless Camera Cards present a different challenge.
When a Camera Card is displayed digitally on a tablet, smartphone, or other device, you don't have multiple physical cards that you can simply place together and photograph.
That's what Pinning solves.
Pinning temporarily combines multiple Paperless subject codes into a single Data Matrix code that the photographer can capture as one keyframe.
Up to three subject codes can be pinned to a fourth, allowing as many as four subjects to be connected to the same photo series.
As codes are pinned, the displayed Data Matrix code changes to represent the combined subjects.
Instead of juggling several devices, opening multiple browser windows, or trying to photograph several digital Camera Cards at once, the photographer still has only one code to photograph.
