Abstract
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.

An apparatus, comprising:
- a first conductive pad operable to detect a presence of a read-head housing of a magnetic stripe reader;
- a second conductive pad non-adjacent to the first conductive pad, the second conductive pad operable to detect the presence of the read-head housing of the magnetic stripe reader;
