1. A card reader that is a component of a point-of-sale system that includes a portable computing device in communication with the card reader, wherein the portable computing device is configured to present a graphical user interface when a payment card is received at the card reader, the card reader comprising:
a slot configured to receive an integrated circuit (IC) chip-type card during a point-of-sale transaction, the IC chip-type card having an IC chip embedded therein and a metal pad on an exterior surface of the IC chip-type card; an electrical contact positioned on an interior surface of the slot and that is configured to conduct across an exterior surface of the metal pad of the IC chip-type card and detect the IC chip-type card when the metal pad of the IC chip-type card completes a circuit with the electrical contact, and the electrical contact is further configured to create an electric signal when the electrical contact is in electrical communication with the metal pad of the IC chip-type card; a plurality of IC chip reading protrusions positioned on the interior surface of the slot and configured to read data from the IC chip embedded within the IC chip-type card; and a controller in electrical connection with the electrical contact, the controller configured to interpret the electric signal when the electrical contact is in electrical communication with the metal pad of the IC chip-type card, the controller is further configured to cause the portable computing device to present the graphical user interface when the IC chip-type card is received in the slot. |
