Abstract
A method of operating a contactless integrated circuit (IC) card reader includes calculating a first transition time of at least one first magnetic pulse during a first transition interval and calculating a second transition time of a second magnetic pulse during a second transition interval. The first transition time is calculated in a calibration phase, and the second transition time is calculated in a detection phase. A contactless IC card is determined to be within a communication rage of the reader based on a comparison of the first and second transition times.
