Abstract

As cheque cards with magnetic stripes are read, flutter (variations of synchronism) may occur, leading to increased error rates. Such flutter is simulated by the proposed arrangement in order to detect and correct read data affected thereby. For this purpose, a data flow, such as that emanating from the read head of a read unit, is produced and subjected to flutter.
