EMV chip cards are payment cards embedded with a microchip that enhances security during transactions. The chip generates a unique code for each purchase, making it difficult for fraudsters to replicate. This technology is widely used in credit and debit cards around the world. When you use an EMV chip card, you typically insert the card into a terminal instead of swiping it. This process is known as "chip and pin" or "chip and signature," depending on the region. The use of EMV technology helps reduce card-present fraud and provides a safer way to make purchases.
