ABSTRACT:
A system for processing articles selected for purchase and bearing an identification code, comprises a code reader for generating output signals indicative of the article identification codes, a first storage unit for storage, for each of the articles, of a signal indicative of a price for the article correlated with the article identification, a second storage unit selectively operable for temporary storage of a signal indicative of a price for an article selected for purchase correlated with the article identification, and a control unit operable on receipt of the code reader output signals for fetching the price-indicative signal from the first storage unit, selectively operable on failure of the price fetching from the first storage unit for accepting operator input of a price-indicative signal for the article and storing the operator input signal in the second storage unit, and for fetching the price-indicative signal for the article from the second storage unit until such time as a price-indicative signal for the acceptable article is fetchable from the first storage unit.
