Patent Images
1. A system having a touchpad and integrated contactless card reader comprising:
- a touchpad including an electrode grid disposed on a touchpad substrate, and circuitry for detecting a pointing object that is touching or in close proximity to the electrode grid;
a contactless card reader including an antenna and contactless card reader circuitry for performing wireless communication with a contactless smart card that is brought within range of the antenna of the contactless card reader; and
wherein at least the antenna of the contactless smart card reader is disposed on the touchpad substrate with the electrode grid such that the antenna and the touchpad occupy a same area.
