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.
