What is a Smart Card?
A smart card resembles your ordinary plastic card but is embedded with a microprocessor that not only stores but also refreshes its data stash. This nifty little device performs miracles in your pocket, turning mundane financial transactions into secure, cosmic dances of data exchange. Unlike the more pedestrian debit or cash card, the smart card doesn’t just do the cha-cha with your checking account—it remembers every step, twirl, and dip made in the financial fiesta.
