1. A card reader comprising:
- a read head;
a plurality of motion sensors in the card reader; and
one or more processors;
wherein the card reader is configured to;
encode card information from the read head,modulate the encoded card information into a signal,receive, from the plurality of motion sensors in the card reader, data describing a gestured signature arc in three-dimensional space, the gestured signature arc having been generated by gesturing using the card reader,identify a two-dimensional plane that provides a best fit to the data describing the gestured signature arc,generate a two-dimensional representation of the gestured signature arc from the data describing the gestured signature arc received from the plurality of motion sensors in the card reader, the two-dimensional representation being a projection of the data describing the gestured signature arc onto the identified two-dimensional plane, andtransmit the signal with the encoded card information to the point of sale system.

Abstract
A method that includes receiving, from one or more motion sensors in a device, data describing a signature arc in three-dimensional space, the signature arc having been generated by gesturing using the device; identifying, from the data describing the gestured signature arc, a plurality of points that correspond to the gestured signature arc in three-dimensional space; generating a curve along the identified plurality of points corresponding to the gestured signature arc; generating a two-dimensional representation of the gestured signature arc; and displaying, on a display screen, the generated two-dimensional representation of the gestured signature arc.
