Abstract
A method for loading data on chip cards (2) wherein data from a service center (6) are transmitted over a mobile network (4) to a SIM card (1), which is inserted in a mobile device (3) and connected thereto via an interface with contacts, and are stored there, and wherein such stored data are transmitted contactlessly from the SIM card (1) to a chip card with contacts (2). The mobile device (3) may, for example, be a mobile radio telephone and the mobile network (4) a GSM or UMTS network. The transmissions are preferably secured and authenticated.
