Abstract
A card exhibiting enhanced detection is provided. A plurality of detector shapes that may be associated with a detection system increases detection effectiveness, while reducing adverse effects of detection systems that may be operating within a electromagnetic field environment.
Claims20
A device, comprising:
- a first device operable to provide a first track of magnetic stripe data to a first read-head of a magnetic stripe reader;
- a second device operable to provide a second track of magnetic stripe data to a second read-head of said magnetic stripe reader;
- a detector operable to detect a read-head housing of said magnetic stripe reader, wherein said first and second read-heads are provided in said housing and wherein a first portion of said detector that extends over at least a portion of said first and second devices contains less material than a second portion of said detector that does not extend over said first and second devices.
