Point of sale terminals

摘要

A keypad circuit provides a signal corresponding to an actuation of a button. A query is presented to confirm intent to place an apparatus in a low-power state in response to the signal. The apparatus assumes a low-power state in response to a confirmation. The apparatus is also configured to assume an active state from a low-power state in response to the signal. Point-of-sale terminals and other apparatus can be controlled and operated accordingly.

主权项

1. An apparatus, comprising:
a chipset to perform respective operations associated with a processor; a user-operable button; a keypad circuit to provide a button signal in response to an actuation of the user-operable button; a super input/output (SIO) to signal the chipset to assume an active state in response to the button signal when the apparatus is in a low-power state; a microcontroller to pass the button signal to the SIO in accordance with a user query when the apparatus is in an active state, the SIO to signal the chipset to assume a low-power state in response to the button signal when the apparatus is in an active state; a housing; and a card swipe reader supported by the housing, the card swipe reader to provide data signaling to the chipset corresponding to a point-of-sale transaction.
