Abstract
The invention relates to a trolley comprising an element for holding and releasing a token, said element comprising a sensor that detects whether the trolley comprising the element for holding and releasing the token is pushed inside another trolley. If this is the case, the element for holding and releasing the token activates the immobiliser and releases the token. In order to use the trolley, a token must be inserted into the element for holding and releasing the token, thus deactivating the immobiliser.
