Patent ID: 8700848

Claim:
A method for transferring data from a first memory card to a second memory card via a managing device comprising a SIM card, each memory card comprising a memory for data, a microcontroller and a unique identification code allocated to the memory card, and allowing reading and/or writing access upon verification of an allocated credential, comprising the steps of: allowing to enter the credentials allocated to the memory cards to the managing device via an application by a user interacting with the application after the credentials assigned to the SIM card has being successfully verified and passing the credentials allocated to the memory cards to the SIM card, where the credentials allocated to the memory cards are stored and protected from being accessed by unauthorized third parties; entering the identification codes of the memory cards by the user and storing the identification codes of the memory cards in the SIM card, where the credentials are allocated to the identification code of the memory cards; connecting the memory cards to the SIM card via an interface of the managing device; reading the identification code from the memory card and transmitting the credential allocated to the identification code from the SIM card to the memory card by the application in order to allow access to the data stored in a memory of the memory card after the credential has been successfully verified by the microcontroller of the memory card; and selecting one memory card as a source for the data transfer and the other memory card as a target for the data transfer via a display of the managing device by the user.
