Abstract
Aspects of the subject disclosure provide a card reader for receiving payment card information at a mobile point-of-sale terminal. In some implementations, a reader of the subject technology can include a memory, a conditioning module and a 3.5 mm audio plug including an audio bus that is configured for insertion into a headphone port of a host device, such as a smart phone or tablet computer. Implementations of the subject technology also include a microprocessor configured to perform operations for determining whether a newer firmware version is available for the card reader or whether a download of such a firmware needs to be completed, and in response to determining such a download is needed, performing a download of the firmware via the audio plug during periods of inactivity.
