There are many areas in retailing in which electronic information processing systems may be applied. The areas of application given consideration for this discussion were the following: accounts receivable, including credit authorization; accounts payable; and unit control. To coordinate all of these functions into one system would have been an ambitious undertaking for this session. Accounts receivable and accounts payable are mechanized to a degree at the present time with electromechanical machines. Unit control, on the other hand, in this store is performed entirely by hand. The volume of data to be processed in the 31 departments is large enough so that one can expect an electronic system to produce a more efficient, reliable, and economical operation.
