Abstract
A dual antiphase read-head arranged card reader is provided. The card reader includes a first read-head arrangement and a second read-head arrangement. Electromagnetic noise is applied to both the first and second arrangements. Waves associated with the electromagnetic noise on the second arrangement is transformed and applied to the first arrangement canceling the noise on a first read head of the first arrangement. The first read head reads magnetically encoded information on a magnetic strip of a card inserted into a card slot of the card reader free of noise. However, the noise remains present such that any skimmer read head of a skimmer inserted into the card slot is unable to read the magnetically encoded information off the magnetic strip of the card.
