Abstract: The pocket connector of the invention has been manufactured of a substrate, which is preferably flexible in at least one direction, of which three parts have been prepared, which are bent or assembled from three parts and joined together superimposed so that at least two opposite sides of the pocket connector have coupling apertures. Two flat cables or a connector for a flexible circuit board is connectable to these coupling apertures.

Abstract: The invention relates to a card, the card (10) comprising identifiers (3), with which the primary use of the card (10) can be implemented. The card is characterized in that it further comprises a solar panel (2) positioned on the card (10) and consisting of solar cells, interface means (21, 22) for transmitting energy collected by the solar panel (2) to devices external to the card in such a way that the card's (10) solar panel (2) allows the card to have an additional use separate from said primary use, the additional use being arranged to forward current supply provided by the solar panel (2) to external devices (40) separate from the card. Further, the invention relates to a card receiver (30) and a system for transmitting electric energy for electronic devices.
