Dongying Student Apartment Electricity Management System, with leading sales and brand guarantee

The user holds an IC card to the power supply department to make payment and purchase electricity. The power supply department uses the electricity sales management machine to write the purchased electricity into the IC card. The user holds the IC card and swipes a non-contact IC card (referred to as card swiping, the same below) in the induction area to turn on the power supply. After power supply, the card is removed. When the remaining battery level in the meter is equal to the alarm battery level, the power off alarm (or buzzer alarm) will be triggered when the switch is turned off. At this time, the user can swipe their card in the sensing area to restore power supply; When the remaining power is zero, the power will automatically shut down and the user must use their card again to purchase electricity before they can resume using it.
