The method comprises the steps of: activating a first contact assignment in response to a first communication protocol present on the contact field and occupying a first part of contact surfaces of the contact field; recognizing a change of the communication protocol from a first communication protocol to a second communication protocol with a protocol recognition unit in the chip card; and activating a second contact assignment in response to the recognized second communication protocol occupying a second part of contact surfaces of the contact field. The first and the second part of contact surfaces of the contact field are selected from an ISO-7816-2 contact field having a maximum of six contact surfaces and the second communication protocol requires at least two data lines."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for the data exchange between a terminal and a chip card","description":"A method includes exchanging data between a chip card and a terminal in a contact-based manner via a contact field.
