Contact smart cards have a copper interface pad embedded on the surface of the card. The card must be inserted into a smart card reader to make a direct connection for the transfer of data. Contact smart cards typically have more memory and processing power than contactless cards. Some data encryption processes (used in high-security financial or legal applications) can only be performed by contact smart cards. Contact smart card readers work well in office environments, but not outdoors or in industrial applications. Below is different series of chips.
