Perhaps you're thinking of I2C?

To see if I understand what your saying -- you want to make a board
that could represent "stories" that you can move around (to being
in-flight, in the icebox, backlog, etc.), and have a computer system
recognize when stories move categories and automatically update a
story-tracking application?

Why make it so complicated and electrical? I think that I would
approach this as a story board where each story has a QR code that can
be scanned and located by a high-resolution camera facing opposite it.
Then, using boundary detection, find each code and figure out its
relative position on the board. This would almost undoubtedly mean
hacking together some OpenCV and other libraries and tools to get
something working.

If you wanted to go at this electrically, I'd suggest taking a look at
the 1-Wire bus. It's a lot like I2C, but made for longer distances at
the expense of slower data rates (probably not a problem for simple,
static IDs, I'd think).

Cheers,
