Abstract
A gasoline refueling nozzle (3) includes a system for preventing theft of gasoline by leaving without payment after refueling. The nozzle communicates both ways with a chip (7) on the car and a central unit (9) in the gasoline station via two air interfaces (5, 6, 8). The nozzle is equipped with an easily legible display (20) and with a built-in battery (17) for its operation, and the battery is recharged inductively from the gasoline pump (2) via an adapter unit.
