During last decade, several utilities implemented prepaid conventional meters in order to mitigate non-technical losses. 

As the first Chinese company to offer STS-certified prepaid meters, Hexing always plays a significant role in developing features and functions of the standardized energy vending infrastructures including meter and system. Over the years, many prepaid metering projects were initiated in form of pilots, and eventually led to the national rollout in several countries due to the satisfactory outcomes and supports of the energy regulators. Nevertheless, conventional prepayment is yet to fulfill all potential capabilities of a flawless energy vending solution! It helps to eliminate bad debts, mitigate collection losses, enhance the cash flow and minimize meter reading and bill generation costs, and many more benefits but still conventional metering platform is vulnerable to tampering and fraud. Furthermore, utilities neither can send a remote command to connect or disconnect the relays, nor do they have a clue about the real time status of the conventional prepaid meters. The manual credit top-up and token transfer failure are other drawbacks of conventional prepaid meters that may affect the operational expenditures of the utilities. In addition to all above mentioned challenges, conventional prepaid solutions may not provide adequate and real time data to support financial audits. HEXING’s Smart Prepayment Solution incorporates cutting edge technology of online prepaid meters with an advanced energy vending system. The state-of-the-art solution is designed in a way to support variety of communication mediums.

Following images vividly illustrate the evolution of prepayment system from a convention toward a smart platform.
