Chipcard is the top level category for all kind of silicone based intelligent devices - ranging from simple memory cards offering cheap limited storage space up to high end smart card crypto controllers with extensive mathematical computing capabilities. Depending on the customer or application needs a chipcard offers a classic contact based interface well known from banking cards or a contactless interface typically used in public transport or building access. Both types of interfaces can be combined within one card body.
Implanting a pure contact based smart or memory chip in a RFID card results in a hybrid card hosting two separated technolgies within one card body.
Dual interface cards
In case application data stored on a chip card shall be accessible as well via classic contact interface as via RFID interface a the dual interface technology is the right choice. A dual interface card contains just one chip with two interfaces.
