In order to control the authorization of a person using a service involving a data carrier (1) which communicates in a contactless manner with a read out device (4), said data carrier takes the form of an object which is worn on the skin, a wrist watch for example. Said object which is worn on the skin, e.g. a wrist watch, is provided with a sensor (3) which is used for the detection of biometric skin identification features and is arranged on the lower side thereof. The skin identification features of the authorized person are stored in a memory unit. If the stored biometric identification features tally with the features thus detected, the read out device (4) emits a release signal.
