Self-service machine i.e. automatic teller machine, has interference signal separating device provided such that total signal is processed to determine desired signal, which supports reading of desired data from magnetic stripe card

摘要

The machine has an interference signal generating unit (11) for generating an interference signal by which an electromagnetic interference field is formed in a region of a card slot so that a total signal (G), which comprises interference signal, is read in a reading unit (4) of a card reader (2). A control unit (10) controls a transport unit (9) and/or the reading unit. An interference signal separating device (15) is provided such that the total signal is processed to determine a desired signal (N), which supports reading of desired data from a magnetic stripe card (7) e.g. bank card.
