PARIS -- Bull's Rock'n Tree, a powerful SIM card, allows an electronic purse to be reloaded via a mobile telephone. The card is used in combination with a two-slot mobile telephone accepting two Bull microprocessor cards at the same time. Rock'n Tree is inserted in one slot and controls the reloading of the e-purse card inserted in the other.
Behind the capability is SIM Rock'n Lab, Bull's tool for the development of applications in Java language. SIM Rock'n Lab has a simple user interface that allows applications to be developed quickly, even by users with no knowledge of Java language.
An application developed with Rock'n Lab is then loaded on to a SIM Rock'n Tree card. For the e-purse reloading application the Rock'n Tree card is inserted into a mobile phone, and an electronic purse card using the Proton technology implemented in Bull's Cash Cards range is inserted next to it in the second slot. This enables the mobile telephone to act as a standard e-purse reloading terminal. Via the telephone screen and keypad, the user calls the issuing bank's e-purse server to reload the e-purse card.
