Smart cards are plastic cards with an implanted microchip that carries certain information. The size of the chip is generally less than a coin, while the rest of the plastic card carries circuits or just creates a comfortable and easy-to-use profile. Such cards 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 can transmit signals over distance, and doesn’t need direct interaction with a control device. Mega Depot offers a selection of smart cards and keys at the best prices.
