Sensor for contactlessly scanning object surface has sensor elements that can be addressed individually for contactless scanning by electronically selecting elements and addressing them

摘要

The device has several sensor elements with individual sensor surfaces (21) forming a sensor matrix (22). The sensor elements can be addressed individually for contactless scanning by electronically selecting a number of elements and addressing them. Several sensor elements are arranged so that elements can be selected with individual sensor surfaces along a circular path (23). Independent claims are also included for the following: a method of contactlessly scanning the surface of an object, especially a coin or similar token.
