In embodiments of a location control service, location data that identifies the location of a device is stored in a memory module, such as secured non-volatile memory or a storage module, of the device along with a timestamp that correlates to local time at the location of the device. After proper authentication, the subscriber can access control over certain predefined behaviors associated with the subscribed line connection, resulting in improved utility and functionality for the subscriber as well as improved busy line interrupt actions. The loyalty system also integrates the activities associated with the user incentive program, with existing payment methods using smart card technology. The reusable handpiece incorporates a probe oscillation mode to assist when inserting the distal piercing tip into tissue. The first path is formed passing through a first set of SVCs and the second path is formed passing through a different second set of SVCs. Two parasitic bipolar junction transistors are formed in the MOS device.
