A card reader for reading magnetic stripe cards which are manually inserted, and withdrawn, by a user. The card is constrained to follow a path which displaces the card laterally while the card is outside the reader, and before the magnetic stripe reaches a magnetic sensor within the reader. The lateral displacement prevents an illicit magnetic sensor, positioned externally to the reader by a hacker, from reading the magnetic stripe, since the stripe is moving in an incorrect direction while the card is external to the reader.
