Method for providing data on at least one area of a chip card

摘要

The method involves providing encryption codes from a location to another location, and providing decryption codes corresponding to the encryption codes from the former location to a chip card i.e. subscriber identify module (SIM) card (10). The encryption codes are used for generating an encrypted data set from a data set. The encrypted data set is provided to a third location. The encrypted data set is transmitted to an area (45) of the card. The decryption codes are used for decryption of the encrypted data set in the data set on the card.
