Abstract
A detection activity of a card may be sensitive to capacitance changes in one or more pads on the card, where a capacitance change detected in a pad during a first time period does not affect a capacitance change detected in the pad during subsequent time period(s). Accordingly, the detection activity may remain sensitive to a faster-moving device with greater accuracy in a determination of position, velocity and/or acceleration of the faster-moving device in relation to the card. A second detection activity may follow a first detection activity, which may increase a probability of a successful communication sequence subsequent to the first detection activity.
