Abstract
The invention concerns a method for making smart cards capable of operating with or without contact called mixed cards and contactless smart cards. In order to avoid the risk of deteriorating the antenna the method consists in producing an antenna comprising at least two turns, on a support sheet, said antenna having its turns located outside the connecting pads, and in providing an insulating bridge so as to connect each of the antenna ends to a connection pad respectively.
