The "golden finger" is just a metaphor. In fact, those on the memory sticks are finger-shaped because of the gold-plated surface. That is, metal pins.

Not every circuit board has golden fingers. Golden fingers refer to circuit board slots. For example, the part of a graphics card or memory bar that is inserted into the motherboard. Sections of contacts, like fingers, are called golden fingers.

Because the color of "bronze fingers" is similar to that of "golden", it is called "golden fingers".
