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.
Claims16
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;
- wherein the first read head is aligned to read a specific track of a card's magnetic strip.
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;
- wherein the electromagnetic noise is generated by a component of the card reader or an external source.
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;
- reading magnetic encoded information from a card using the first read-head portion while the electromagnetic noise remains on other read-head portions;
- and
- preventing unauthorized reading of the magnetic encoded information due to a presence of the electromagnetic noise on the other read-head portions.
