Abstract
An operating volume of the NFC transceiver of the electronic device may be extended or enhanced via a resonating circuit disposed in a case that attaches to or covers an electronic device. The resonating circuit disposed in the case may amplify an NFC signal output by the NFC transceiver of the electronic device, extending or enhancing the operating volume of the NFC transceiver of the electronic device such that an external NFC antenna may communicatively couple to the NFC transceiver of the electronic device at a greater distance from the NFC transceiver of the electronic device than would otherwise be possible without the resonating circuit. Extending or enhancing the operating volume may enable the NFC transceiver of the electronic device to perform actions such as executing transactions, receiving information, transmitting information, and so on at a greater distance than otherwise possible, improving ease of use and user experience.
