I think edge-punched cards were primarily used for transaction and account data
storage with electronic accounting machines during the period when small and
medium size organizations were transitioning from completely manual accounting
and record-keeping systems to computerized ones. They were essentially a
variation on things like mag-stripe ledger cards used with the Burroughs
Sensitronic and E-series accounting machines. I remember seeing the edge-punch
card equipment attached to a Burroughs TC-series machine in the early 1970s.
Royal McBee? used to have an edge punch card system, larger cards.
In my high school, they had a bunch of large edge punch cards to "help" us
pick colleges. Poke multiple needles through the holes, and the ones that
were edge punched in those columns would fall out.
