A device for determining a thickness or thickness variation of a flat object (), in particular of a voucher, is proposed, having at least one first guide element (), and having a plurality of second guide elements () arranged next to each other in a row and opposite the first guide element (), wherein the flat object () can be transported between the first guide element () on the one side and the second guide element () on the other side, and having a displaceable arrangement of the second guide elements () relative to the first guide element () in order to bring about a displacement of one or more of the second guide elements () in the event of a thickness variation of the flat object () passing between the guide elements (), and having several coils () fixed in location, wherein each second guide element is associated with at least one coil (), and having at least one coil core () rigidly connected to a second guide element () and displaceably guided in the coil associated with the second guide element (), wherein a deflection of a second guide element () brings about a deflection of the associated coil core (), and having an analysis device () to determine the influence of the position of the coil cores () relative to the coils ().
