1. A data store for use with capacitive reading, having capacitive electrodes (1) and (9) which establish galvanic connection to data elements constituted as impedances, c h a r a c t e r i s t i c i n that each impedance at least consists of a resistive connection (3) between kapaci- tive electrodes (1), (9).

2. A data store according to claim 1, c h a r a c t e r i s t i c i n that each impedance is constituted as a parallel connection of a resistor (3) and a kapacitor (2,.5)

3. A data store according to claim 2, c h a r a c t e r i s t i c i n that it consists of a number of first electrodes (2),. each being associated with a capacitive coupling electrode (1) and a common second electrode (5) which is connected to a particular coupling electrode (9) , and in that a resistive connection (3) is established between first electrodes (2) and said second electrode (5) .

4. A data store according to claim 1, c h a r a c t e r i s t i c i n that each impedance is constituted as a parallel connection of 2 or more resistances, each having an individual overload capacity.

5. The use of a data store according to claim 1 in conjunction with the changing of a data element, c h a r a c t e r i s t i c i n that energy is capacitively fed into the data store, said energy being sufficient to destroy the resistive part (3) of the data element impedance.

6. A procedure for the manufacture of a data store according to claim 3, c h a r a c t e r i s t i c i n that a conductive pattern is deposited on an insulating carrying foil (6), said pattern constituting coupling electrodes, first electrodes, second electrode, data capacitors, and resistive connections, whereupon the insulating carrying' foil is folded in order that said second electrode overlaps all first electrodes in a generally uniform manner.

7. A procedure for the manufacture of a data store according to claim 4, c h a r a c t* e r i s t i c i n that a conductive pattern is deposited on an insulating carrying foil (6), said pattern constituting coupling electrodes and resistive connections.

8. A procedure for the manufacture of a data store according to claim 3, c h a r a c t e r i s t i c i n that the conductive pattern is supplied with an insulating covering prior to folding.

9. A procedure according to claim 6 or 7, c h a r a c t e r i s t i c i n that the conductive pattern consists of a resistive material.

10. A procedure according to claim 6. for the manufacture of a data store according to claim 2,- c h a r a c t e r i s t i c i n that the material which is deformed at the fold (8) is cut away subsequent to relative fixing of the folded parts.
