Two types: electroless nickel immersion gold and electroplated hard gold.

Because it has the highest corrosion resistance and electrical conductivity after copper and silver. Gold is sometimes used in combination with cobalt and nickel to increase the wear resistance of the fingers.
3. What is Goldfinger?
Gold fingers are gold-plated, narrow connectors on the edge of a printed circuit board that enable connections between multiple circuit boards. They are made of meat gold, the hardest form of gold available, which works for long periods of time and has excellent conductivity.
