We've seen kids at a cash register practically in tears trying to make
change when the power went out.

Most store these days have no provision for selling anything without
using the UPC scanner, quite apart from the onerous task of figuring out
the change. Even writing down the UPC no. on a piece of paper doesn't
work, because the store identifies an item not by the UPC but by the SKU
-- and only the computer system knows how they are related.

The UPC is Morse Code, can't help with the SKU. I wonder if WalMart has
an extra set of cash registers independent of their computer system in
case of a major computer crash?
