prepaid electricity meter    are also called quantitative energy meters and IC card electricity meters. In addition to the measurement functions of ordinary energy meters, the special thing is that users buy electricity first, and then use electricity after buying electricity. If the electricity is used up, users do not continue When you buy electricity, it will automatically cut off the power and stop the power supply.


There are two pre-stored methods, one for code and one for card writing.

The code principle is as follows: the management system combines the user information and the electricity purchase information to generate a set of encrypted codes, and hands them to the user to input into the electricity meter. After the electricity meter is correctly decrypted, the pre-stored electricity or amount is obtained and saved.

Card writing method: Write the pre-ordered electricity or amount into a dedicated electronic card (memory), and give it to the user to hold the electronic card to the corresponding electric meter for communication. The pre-order value is automatically sent to the electric meter.
Electronic cards or IC cards, also known as power purchase cards, are made of special IC chips after special packaging. Common power purchase cards are divided into contact and non-contact according to communication methods.
Contact type: card card, key card, non-contact type: RF card, remote control card
