1. A card, comprising:
a processor having a plurality of ports to detect movement of an object relative to said card based on signals detected at said plurality of ports;
a first array of sensors arranged along a first length of said card; and
a second array of sensors arranged along a second length of said card, wherein sensors of said first array are coupled to a first port of said plurality of ports and sensors of said second array are coupled to a second port of said plurality of ports to produce a first sequence of said signals based on a first direction of said movement and to produce a second sequence of said signals based on a second direction of said movement.
