Smartcards are special plastic cards with implanted microchip, which carries certain information. The size of the chip is generally less that a coin, while the rest of the plastic card carries circuits, or just creates a comfortable and easy-to-use profile. Such card can carry ID info that provides access to a control system, bank accounts, mobile network etc., or carry data. A proximity card is an improved version of a smart card - it utilizes the same working principle, however it’s able to transmit signals over distance, and doesn’t need direct interaction with a control device.
