Abstract
A method of protecting a magnetic card inserted into a card reader in a self-service terminal is described. The method comprises detecting presentation of a card at a card reader; energizing an electromagnetic signal transmitter in response to detecting presentation of the card; detecting a change of state of a width switch; de-energizing the electromagnetic signal transmitter in response to detecting the change of state of the width switch; detecting a magnetic signal from a pre-read magnetic reader; and re-energizing an electromagnetic signal transmitter in response to detecting the magnetic signal from the pre-read magnetic reader.
