In our estimation, the great majority of supermarkets will participate in some form of electronic payment system before 1990, and there will there fore be investment in debit-card readers (credit-card readers) which can be linked to point-of-sale terminals.
Det er vort skøn, at det overvejende antal af supermarkeder vil deltage i en form for elektronisk betalingsformidling inden 1990, og at man derfor vil investere i købekortlæsere (kreditkortlæsere), som tilkobles kasseterminalerne.
