Abstract

One or more detection activities of a card may allow calculation of rolling speed in motorized readers. Accordingly, the detection activity may result in a data transmission speed with greater accuracy after a determination of position, velocity and/or acceleration of the faster-moving device in relation to the card. Such detection activities may increase a probability of a successful communication sequence.
