1. A method of detecting that a component of a mobile device other than a card reader connected to an audio jack is a source of an input signal comprising: detecting that the card reader is connected to the mobile device via the audio jack of the mobile device, the mobile device having the audio jack and a microphone source as two separate components for receiving input signals from an external signal sources; invoking an application to read captured card information sent from the card reader in response to a swipe of a transaction card; determining that the mobile device is not processing the captured card information sent from the card reader; in response to determining that the mobile device is not processing the captured card information sent from the card reader, determining that the mobile device is reading an input signal from the microphone source rather than the audio jack when the card reader is connected to the mobile device via the audio jack, the determining that the mobile device is reading the input signal from the microphone source based at least in part on determining that the input signal includes audible noise elements; and in response to determining that the mobile device is reading an input signal from the microphone source, changing, by the mobile device, the mobile device to processing the captured card information sent from the card reader.
