<p>A smart card wallet with one or more smart cards. The smart card wallet includes a microcontroller connected to a data bus and one or more smart card readers. The smart card(s) in the wallet are connected to a respective reader. The microcontroller is also connected to a communication stage, such as, for example, a short range radiotelephone transceiver. The communication stage transfers data to/from the smart card(s) in the wallet to a mobile radiotelephone via a data channel over the radio air interface. The mobile radiotelephone is thus used to mediate transactions between the smart card(s) in the wallet and parties to the transactions (e.g., merchants, banks, other wallets, etc.). An embodiment provides each smart card(s) in the wallet with a separate internet protocol (IP) address. Consequently, in this case, the smart card wallet includes a local IP-based network.</p> |
