The prepaid meter is important in making the consumer having sense about his/her energy consumption which is important in eliminating the difficulties facing the electrical utility employee in getting the reading of the conventional electromechanical meter and eliminating any error incurred in bills issuing. This paper is aimed at developing a prototype of a management system for a prepaid electrical power meter. The designed prepaid meter consists of an RFID reader, a microcontroller, a digital meter and a wireless gateway. The proposed prototype metering system consists of two parts: clients and server. An RFID reader is used to read the ID of the credit card and a PC connected to a hardware simulated circuit which is designed and implemented to simulate the operation of the digital meter. The server is located in the local substation which receives the card’s ID from clients and sends ID’s information back to the client after checking and/or updating the database.
