@spoctalvideos: Those tiny gold-colored contacts on old SIM cards aren’t just for looks — they can contain a very thin layer of real gold. 💳💰 Gold is used in electronics because it conducts electricity extremely well and resists corrosion, making it ideal for reliable electrical contacts. The amount inside a single SIM card is incredibly small, but when hundreds or thousands of discarded cards are processed together, tiny quantities of gold can potentially be recovered. That’s one reason electronic waste can be surprisingly valuable: phones, circuit boards, connectors and SIM cards can all contain trace amounts of precious metals. Your old SIM card probably won’t make you rich… but a bucket full of them suddenly looks a lot more interesting. 👀 #gold #simcard #technology #ewaste #recycling
