A MOBILE TERMINAL UTILIZING SECURE WIRELESS TECHNOLOGY TO CHARGE PREPAY UTILITY METERS ESP.FOR PIPED NATURAL GAS (PNG)

摘要

This invention relates to using a wireless smart terminal to access the electronic smart card reader built inside a utility device installed by the utility company supplying electricity, gas or water. While this invention describes in details relevant to Piped Natural Gas (PNG) as an example, it should be considered broad enough in its scope whereby many of the embodiments will also be applicable to water and electric meters. The terminal can access the meters to perform diagnostics on the electronic circuitry, initialize the stored parameters, force a simulated condition, read a current value in the e-Purse of the consumer card or the memory of the meter, clear the value, top up the value, or make changes to display parameters such as - messages, customer ID, meter ID. etc.
