GoldCard Exhibit

Exhibit is the Goldcard Power-Tech app for learning about the company and its smart metering products, and for trying the operations used on a prepaid meter. On the home screen you can select a meter and see whether it is online, whether the relay is connected or disconnected, and the latest readings: voltage, current, load power, total consumption, balance in kWh, and the last read time. Reading refreshes the meter data. Top up adds credit in USD and increases the balance in kWh, with each top-up saved in Top-up history. Relay Control asks you to confirm, then connects or disconnects the meter. Usage is shown in three views: today’s load profile, daily energy for the last 30 days, and monthly energy for the last 12 months. The meter list includes the meters provided for this app. You can also add a meter by entering its number or scanning a code, and remove a meter you added. Products introduces Goldcard Power-Tech prepaid meters, metering solutions, and company news. A company overview video plays inside the app. About includes the company profile, contact details, and a link to goldcard.top. Exhibition Registration opens the visitor registration page inside the app.
