Abstract
A credit verification system is disclosed including remote terminals and a central unit, for use with identification cards carrying a changeable recording medium. On presentation, cards are sensed to provide signals indicative of identification with (1) an aggregate amount of all value transactions supported by the card during a period (month) and (2) an aggregate amount of all those value transactions occurring at 'off-line' stations or terminals during the period. Each terminal senses signals indicative of amounts of values as a control, depending upon the current mode of operation for the terminal involved, e.g. 'off-line' or 'on-line.' Approval is indicated in either state, providing the card is acceptable under established criteria for each state, e.g. that the imposed limits are not exceeded.
