A detection activity of a card may be sensitive to capacitance changes in adjacent and non-adjacent pads on the card. Accordingly, the detection activity may remain sensitive to faster-moving devices and / or reduced detection sampling rates. 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. A card may, therefore, immediately transition to a low-power mode of operation after verification to reduce power consumption.
