If your electricity meter has been replaced since January 2009 with a digital meter, it is likely a smart meter. Smart meters have a white face, with an LCD display, short for liquid crystal display, which is similar to the display used in digital watches and many portable computers and televisions. If you still have a meter reader visiting your house to take regular readings then you don’t yet have a smart meter. Another way is to check is that sometimes, depending on your utility, your monthly utility bill will have a statement in the "Notes" section indicating that your home is equipped with a smart meter.
