Abstract
Abstract A data identifying system for identifying information recorded in a recording medium comprises: a discriminable card like a credit card having a magnetic stripe; a memory medium like an optical ROM card having an accident card list in which data regarding invalid cards (accident cards) is stored; a first reading unit to read the data stored in the memory medium; a discriminating circuit to discriminate whether the card is invalid or not on the basis of an output of the reading unit; a circuit to inform the fact that the card is invalid when it is decided to be invalid; and a second reading unit to read the data recorded on the card.
