1. A device for communicating data with a contactless smart card, comprising:
- a housing having a first axis in a substantially horizontal plane, the housing comprising;
a front surface having an opening for accepting the contactless smart card;
a back surface having means for mounting said housing;
a cavity extending from the opening towards the back surface in a direction parallel to the first axis, the cavity comprising;
a bottom surface adjacent the opening and sloping toward the opening at an angle with respect to the first axis; and
and a top surface at least partially overhanging the bottom surface;
an antenna parallel to the bottom surface of the cavity, the antenna producing an electromagnetic field at least partially within said cavity; and
electronics coupled to the antenna for controlling data communication with the smart card via said antenna.

Abstract
A device for communicating data with a contactless smart card in which a user initiates such communication by at least partially inserting the smart card through an entrance to a cavity of the device. The electromagnetic field produced by the device is largely confined to the cavity and largely oriented in a vertical direction. This structure prevents unintended communication with a smart card carried in a person'"'"'s shirt pocket and minimizes potential health risks from exposure to the field. It also discourages users from moving the card too quickly into and out of the field for a transaction to complete.
