Card reader and method of use thereof

Abstract

A representative card reader that communicates with a host device comprises an EMV chip interfacing circuit that facilitates transmitting and receiving data to and from a Europay, Mastercard, and Visa (EMV) chipcard; and a computing device that is electrically coupled to the EMV chip interfacing circuit. The computing device receives and processes the received data from the EMV chip interfacing circuit, and transmits processed data to the EMV chipcard via the EMV chip interfacing circuit. The card reader further comprises a uni-directional interfacing circuit that establishes communications between the computing device and a host device without the need for specialized software drivers, with the simplicity for capturing the card data in a native OS system of the host device for transfer to a financial payment application, and applicable for both browser based or application based software on the host device. The uni-direction interfacing circuit communicates with the host device to transmit electrical signals associated with the processed data from the computing device.
