FuelPOS - FuelPOS is a Java™-based application that runs on either a laptop or handheld device carried in the fuel truck. Sun Microsystems’ Java Runtime Environment is a relatively new technology that is commonly used in Internet-based and distributed networking applications. The underlying principle behind our on-the-truck software is that it’s a recording device – not a standalone solution. As such, it allows fuel truck operators to do their jobs without having to deal with the complexity of maintaining an entire accounting system.
