Abstract: A point-of-sale (POS) device includes a processor, a universal serial bus (USB) hub, two switches, and an external connector that connects the POS device to a secondary device with its own second processor. In a primary mode, the processor is connected to a host connector of the USB hub and the secondary device is connected to a first peripheral connector of the USB hub via the external connector. In a secondary mode, the processor is connected to the first peripheral connector of the USB hub and the secondary device is connected to the host connector of the USB hub via the external connector. The processor controls the switch from the primary mode to the secondary mode, and vice versa, by transmitting control signals to control pins of the two switches, and optionally by transmitting a reset signal to a reset pin of the USB hub.

Abstract: Aspects of the technology provide an electronic device having a touch display and a method of detecting any possible tampering with the electronic device using the same ITO traces of a conductive grid of the touch display that are used to drive the touch display for displaying information and/or sensing touch inputs.

Abstract: A payment object reader or POS device tracks performance of a wireless transceiver. In response to detection of a dip in performance of the wireless transceiver, the payment object reader or POS device retunes the wireless transceiver, enables a first subsystem of the payment object reader or POS device from a disabled state, transmits a notification indicating a defect, or identifies a tamper attempt. Sensor measurements and other actions within the payment object reader or POS device can be correlated with wireless transceiver underperformance and used to predict actions to take.

Abstract: A point-of-sale (POS) device includes a processor, a battery, a transaction object reader, a printer with a printer controller, and optionally a temperature sensor. The processor determines a present power discharge capability rate of the battery, optionally based on a temperature measured by the temperature sensor. The processor also calculates a first estimated power draw rate based on a first setting value for at least one of the components of the POS device, such as the printer. If the first estimated power draw rate is dangerously close to the present power discharge capability rate of the battery, a second estimated power draw rate is calculated based on a second setting value for the one or more components. If the second estimated power draw rate is no longer dangerously close to the present power discharge capability rate of the battery, the components are set to the second settings value.
