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.
Claims21
(canceled)
A method, comprising:
- applying electromagnetic noise on read heads of a card reader;
- canceling the electromagnetic noise on a first read head of the card reader;
- and
- reading magnetic encoded information from a card using the first read head while the electromagnetic noise remains present on other read heads.
A method, comprising:
- providing a card reader with multiple read-head portions;
- applying electromagnetic noise to the read-head portions;
- canceling the electromagnetic noise on a first read-head portion;
- and
- reading magnetic encoded information from a card using the first read-head portion while the electromagnetic noise remains on other read-head portions.
A system, comprising:
- a card reader including:
- multiple read heads;
- a noise generator configured to apply electromagnetic noise to the read heads;
- and
- a noise cancellation mechanism configured to cancel the electromagnetic noise on a first read head while allowing the electromagnetic noise to remain present on other read heads;
- wherein the first read head is configured to read magnetic encoded information from a card while the electromagnetic noise remains present on the other read heads.
