Title
Monitoring the Docking States of Portable Payment Terminals in Mobile Point-Of-Sale (MPOS) Systems
Abstract
A portable payment terminal (PPT) that is used to facilitate customer transactions in a mobile point-of-sale (MPOS) system is assigned to a particular tablet device. The PPT device may dock with to charge its batteries, and undock from the tablet device to facilitate customer transactions. To maintain a requisite one-to-one relationship between the two devices, a timer is started whenever the PPT device is undocked from the tablet device. Additionally, checks are performed to ensure that the PPT device is authorized to dock with the tablet device. If the PPT device remains undocked from the tablet device for a predetermined time period, or if the PPT device is not authorized to dock with the tablet device, the functions of the tablet device and/or the PPT device are disabled to reduce or eliminate the usability of the devices to a user.
