A medical-technical identification device for identifying a sterile product and a method of identifying such a product are provided. The product may be intended for one-time-use only, when connected to a piece of medical equipment. A fixedly mounted information carrier is adapted to deliver or to offer specific product information in a contactless fashion to a reading element connected to the medical equipment. The function of the identification device is improved so that even specific data can be forwarded to the medical equipment such as an infusion-type fluid pump. Thus operation of the pump may be reprogrammed, for example, to change the calibration factor or the operation mode or to change irrigation depending on the patient group to undergo surgery.
