Nowadays, everyone’s pursuit of the quality of life is getting higher and higher. More users use more prepaid meters. So how do you operate the prepaid electricity meter?
- The user holds the electricity purchase card to purchase electricity on the special computer of the local power supply department, and the sales motor writes the encrypted information and the electricity purchase fee into the electricity purchase card.
- As far as possible, users are required to insert a card into their own meter before purchasing electricity.
- After purchasing electricity, the user inserts the electricity purchase card into his own energy meter IC card slot for a few seconds. After the LED displays, pull out the electricity purchase card, and the energy meter will write the electricity consumption status on the user's electricity purchase card at the same time. When the user purchases electricity again, the write-back data is read by the management system for electricity management.
- Provide special function cards such as zero reset card and digital reset card for electricity sales and power supply management departments. This type of card can generally be reused with restrictions, while the electricity purchase card of electronic energy meter can be reused.
