The telematics infrastructure (TI) connects doctors, dentists, psychotherapists, hospitals, pharmacies and health insurance companies. Only registered users from the health care professions can access the TI with their SMC-B card. The aim is to make medical information for treating patients available faster and easily, and to improve the exchange of information and the quality of medical care. The TI is operated by Gesellschaft für Telematikanwendungen der Gesundheitskarte (gematik). The word 'telematics' combines the words 'telecommunications' and 'informatics'. It refers to the interconnection of different IT systems in the health sector.
