Abstract
An electrical circuit, for example a printed circuit, for producing a module for integration into a card such as a chip card. This module includes electrical contact or connector which includes lands for the connection and communication of the chip with a read/write system. To give them a white color, or a color close to white, these electrical contact lands are at least partially covered with a layer of a rhodium alloy. The invention also relates to a method for manufacturing such an electrical circuit.
