Abstract
A data carrier (1) includes a chip (10) having a supply voltage circuit point (12), from which a supply voltage (V) can be taken, and having at least one supply voltage output (21, 22) for supplying a supply voltage (V1, V2), and having potential control means (35, 49) to which a control signal (S) can be applied and with the aid of which the supply voltage output (21, 22) can be set to different potential values in accordance with the control signal (S), and also includes at least one component (24, 29) which is spatially separated from the chip (10), which component (24, 29) has a supply voltage input (25, 30) is connected to the supply voltage output (21, 22) of the chip (10) via a connection lead (27, 32).
