Overview
Near Field Communication (NFC) is used for real-time precision marketing based on time, local inventory and the individual when embedded in product displays or the products themselves. NFC is also becoming the preferred method for payment either in smartphones or smart payment cards.
In this particular deployment , the overall system consists of Backend Servers, Top Up station and Household Meter.
The Backend Server roles are to activate the new installed meter, to collect meter usage data and behaviors, to implement new tariff based on user behaviors, and to allocate energy usage in effective way.
Top Up Stations are NFC Reader with SAM and they are connected to local Computer, Tablet or Mobile phone. They are located at retailers near by household to ease the user to buy the credits. Besides that, Top Up Station is also help to upload and download settings or parameter from the Backend Server
Household Meters are those Contctless Prepaid Meter has been installed at end user
