MUNICH, GERMANY: With its NFC-capable SkySIM CX SIM card, Giesecke & Devrient (G&D) is providing the key security component for Deutsche Telekom's digital wallet, known as MyWallet. MyWallet can be used by all Deutsche Telekom mobile network customers with an NFC-capable smartphone.

As a security partner, G&D is also supplying the MasterCard PayPass payment application to enable secure electronic payments to be made via the ClickandBuy International Ltd's virtual credit card system as the first product in Deutsche Telekom's digital wallet.

User-friendly payment applications - and, in future, ticketing and identification applications too - place particular demands on SIM card security. Together with G&D, Deutsche Telekom has come up with a security architecture for NFC-capable SIM cards that meets these specific challenges.

These SIM cards feature a secure data vault, with the full version offering a data volume of up to 1.3 megabytes. The SIM cards also contain a powerful processor that is capable of loading the required applications within an extremely short space of time, in spite of the encryption and decryption process. These applications, such as credit card functions and the data they require, are stored in specially secured areas of the card.
