That doesn't sound like a software problem.  All the automated self-serve
stands I've seen use weight as a primary factor, but this requires that
the data on the acceptable weight-range be properly encoded in its
database.  When that happens, a 5 pound box of hardware with the UPC
0-12345-67890-1 will scan fine as long as it's within the listed
acceptable weight range for the product, like maybe 4.9-5.1 pounds.

Hey but you don't mind going over to the register manned by a clerk and
letting him/her scan your purchases, now, do you?

Because THAT was a total train wreck when it first came out.  The early
systems never really panned out, and many stores who invested early on
in the technology found themselves reinvesting in newer technology within
a decade.  Those that didn't tended to suffer as they coped with limits
inherent in the systems.  Customers were distrusting of the technology;
some stores handed out markers so that customers could write the prices
of the items on the items so that they could verify their receipts later.
Problems were so common that many states implemented laws about scanner

But today, thirty years later, this stuff mostly Just All Works Right.
Actually it worked pretty well even fifteen years ago.

Consumer technologies may change faster.  For example, it wasn't that
long ago that we were keeping a written grocery list on the fridge.
Today, it's all electronic.  The kids can scan(!!!) an item that we 
need, and it magically forwards to my phone and my wife's phone, and
we can even shop cooperatively in a store with realtime updates of 
the list.  The technology isn't 100% perfect, but it's way awesomely
better than a paper list.

It'd be nice to be able to query the fridge to see what's in it.

So I don't expect that the fridge makers will do better ... this year,
or next.  But in five or ten years?  Yeah, maybe, probably even.
