A system for locating and identifying at least two separate items, for example packaging, includes a capacitive first sensor detecting a first measuring region at a first position of a sensor device, for example a sensor film on a shelf bottom for packaging, a capacitive second sensor detecting a second measuring region at a second position, differing from the first position, of the sensor device, an electrically conductive first mark of a first item in the measuring region of one sensor, an electrically conductive second mark of a second item in the measuring region of the other sensor, and an evaluation device evaluating signals from the sensors, the signals caused or changed by electrical conductivity of the marks. Items can be capacitively detected and information obtained can be used to improve warehousing. The sensors and the marks can be produced quickly and cost-effectively by printing processes or film transfer.
