1. A near field communication (NFC) system, comprising:
a mobile payment reader having a reader circuit coupled to a first NFC antenna, wherein the mobile payment reader has a front surface and a back surface opposite of the front surface, and wherein at least a portion of the front surface forms a display screen; and
a casing coupled to the mobile payment reader, the casing having at least a first portion extending from the mobile payment reader and a second portion covering at least partially the back surface of the mobile payment reader, the casing having circuitry comprising a second NFC antenna positioned on the second portion of the casing and a third NFC antenna positioned on the first portion of the casing, the third NFC antenna electrically coupled to the second NFC antenna by at least one conductive connection such that payment data carried by an NFC signal from a payment device and received by the third NFC antenna is transmitted to the second NFC antenna by the at least one conductive connection and is wirelessly transmitted by the second NFC antenna of the casing to the first NFC antenna of the mobile payment reader through the back surface of the mobile payment reader.
