What are the raw materials to make a sim card?

The primary raw materials used to make a SIM card include polyvinyl chloride (PVC) or other plastic substrates for the card's body, as well as metals such as gold, nickel, and copper for the electrical contacts and circuitry. Additionally, silicon is used for the microchip embedded within the card, which stores the subscriber's information. Other materials may include adhesives and inks for printing. Overall, these materials work together to create a functional and durable SIM card.
