The invention relates to a belt (1) having a back surface (2), comprising a data-transferring device (3, 6, 7, 8, 9, 10), wherein the data-transferring device (3, 6, 7, 8, 9, 10) has at least one sensor (6) having an energy supply and has at least one external reading device (9). The problem addressed by the invention is that of designing the data-transferring device mentioned above in such a way that data can be reliably transferred from a moving belt (1) to a stationary receiver (9). Said problem is solved in that signal surfaces (3) spaced apart in the direction of travel of the belt (1) are arranged on the back surface (2) of the belt (1), and each signal surface (3) can be switched either into a first active state or into a second inactive state by the sensor (6), wherein in the first active state a positive signal can be transferred and in the second inactive state either a negative signal or no signal can be transferred and, while the belt (1) is moving, the state of the signal surfaces (3) can sensed by the external reading device (9) during passing. Because only one piece of binary information can be transferred per signal surface (3), the information density is so low that, even if the signal surfaces (3) move past the reading device (9) quickly, the states of the signal surfaces (3) can be reliably sensed. Therefore, even if the belt (1) travels quickly, reliable sensing of the data to be transferred by the sensor (6) is ensured.
