COUNTY HALL, A6352, AYKLEY HEADS, DURHAM, COUNTY DURHAM. Office workers operating IBM 056 card verifier machines in the new County Offices at Durham.
A keypunch was a device used for precisely punching holes into cards at specific locations, determined by the keys struck by a human operator. The verifier operators entered exactly the same data as the keypunch operator, and the machine then checked to see if the punched data matched. The IBM 056 machine was the verifier companion to the IBM 024 Card Punch and IBM 026 Printing Card Punch
