Chip card of reduced size with backward compatibility and adapter for a reduced size chip card

摘要

To achieve backward compatibility for smaller chip cards, in particular to legacy card readers/writers or legacy mobile terminals, according to the present invention a smaller chip card comprises a card body and a first contact area ( 14 ) with dimensions and locations of contacts according to predefined standard. An integrated circuit chip ( 36 ) is, firstly, physically and electrically connected to contacts of a second contact area ( 38 ), where the locations of contacts in the second contact area ( 38 ) are different from locations of contacts in the first contact area ( 14 ). According to the present invention, the integrated circuit chip ( 36 ) is also connected to contacts in the first contact area ( 14 ).
