An integrated self-checkout system and method incorporates access control, electronic article surveillance (EAS), and radio frequency identification (RFID) subsystems, and allows marketing advertisements and pricing to be directed to a specific individual. The customer uses either a cell phone or an interactive personal digital assistant (PDA) when in the store, which displays prices and/or advertisements. The prices and advertisements are selected according to the customer's buying habits. The customer's buying habits are obtained by tracking the customer in the store and recording selected parameters such as the customer's track through the store, the time spent in various locations in the store, items selected by the customer, and items purchased. A database of customer habits is input to a decision program that determines the content of advertisements, and the pricing of various items. In addition to the customer's cell phone or PDA, the advertising and pricing can be communicated to the customer through shelf price displays and fixed displays strategically positioned in the store. RFID or bar code scanners are used to identify the items selected by the customer, and EAS functions can be deactivated for the specific items purchased.

The PMU of claim 50, wherein said POR circuit is further configured to provide a start POR control signal to said external controller once at least one LDO has a voltage level above a predetermined LDO voltage lockout threshold level. 52. A power management unit (PMU) comprising: a substrate; and an adapter detector configured to receive a signal representative of the voltage of an external device and to provide a detector output signal representative of the presence of an adapter, said detector output signal providing a positive indication if said adapter is a continuous output adapter or said adapter is a pulse output adapter, said adapter detector coupled to said substrate; and a multi-function output charge status pin. 53. The PMU of claim 52, wherein said multi-function output charge status pin is configured to display the presence of an adapter when said adapter detector provides said positive indication. 54. The PMU of claim 52, wherein said multi-function output charge status pin is configured to display the absence of an adapter when said adapter detector does not provide said positive indication. 55. The PMU of claim 52, wherein said multi-function output charge status pin is configured to provide an end-of-charge signal when the voltage of said battery reaches a maximum voltage level. 56. A power management unit (PMU) for providing power management and supply functions to a device having a battery, comprising: a substrate; a bi-directional pin coupled to said substrate and configured to serve as an input pin during a first condition and as an output pin during a second condition; a means for providing a first conditioning charge to said battery and second full charge to said battery, said means coupled to said substrate and said bi-directional pin; a means for detecting the presence of an adapter and providing a positive indication if said adapter is a continuous output adapter or a pulse output adapter, said means for detecting coupled to said substrate; a means for protecting the PMU from starting up if the voltage of said battery is below a threshold lockout enabling voltage level and from shutting down until the voltage of said battery is below a threshold disabling voltage level, said threshold lockout disabling voltage level set lower than said threshold lockout enabling voltage level; a means for switching so that an external switch coupled to said switching means may have multiple functions; and a means for enabling at least one LDO to provide power to an external controller if said at least on LDO has an output voltage greater than a predetermined LDO threshold voltage level. 57. A method of inputting and outputting power to and from a power management unit (PMU) having a voltage source comprising: connecting an external device to a bi-directional pin of said PMU; triggering a first condition or a
