Abstract: Example embodiments of the systems and methods of card reader protection disclosed herein combine motorization technology with payment card industry (PCI) protection technology. In an example embodiment, access to the card is protected by a mesh grid inside a printed circuit board (PCB). In one embodiment, there are five mesh grid walls in total. A secure signal is used to transmit data. The data is transmitted along traces embedded within the circuit boards. When a signal trace extends from one layer of the PCB to a second layer, the traces on the separate layers are connected with a via hole that extends between the layers and electrically connects traces on different layers. In an example embodiment, one or more of the boards fit together with slot joints. The vias are positioned in the board such that they are hidden due to the slot joint configuration.

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.

Abstract: An automatic identification system includes a reader device, such as a bar code wand, laser bar code reader, CCD, m or combination of reader devices, such as magnetic stripe reader, badge slot reader, or touch memory pen. A slave interface is provided for transferring raw reader signals from the reader device to a communication port of a personal computer. The invention provides a hardware and software system which permits interfacing of multiple reading devices and device types into a single port, and which provides efficient power management.
