On a portable data carrier () with a communication interface () and a control device () the control device () allows a transaction in a communication network () between a communication device () connected with the data carrier () via the communication interface () and a network server (). For this purpose the control device () sends, in response to a request (S; S) concerning a transaction between the communication device () and a network server (), received from the connected communication device () via the communication interface (), a request redirection message (S; S) concerning the transaction to the communication device ().

Internet-smart-card

In a method for writing (S, S) of operating data () through a writing system () comprising a central station () and at least one distribution station () to a portable data carrier () connected with the at least one distribution station () within the framework of a production of the data carrier () there is generated (S, S) an individual addressing for the data carrier () connected with the at least one distribution station (), via which addressing the data carrier () is uniquely addressable system-wide upon the writing (S, S) of the operating data (). In doing so, at least a part of the system-wide unique individual addressing can be generated (S, S) by the data carrier () itself or by the distribution station () with which the data carrier () is connected.

Writing operating data into a portable data carrier

In a method for providing data for a data processing device () by a web server () of a data carrier (), the web server () of the data carrier () receives () a data request message from the data processing device () connected with the data carrier (), the data request message relating to a provision of data for the data processing device (). Then the web server () responds () to the data request message by sending a data provision message which comprises the requested data. For this purpose, the web server () either reads out the data from a non-volatile memory () of the data carrier or obtains these, if the data are not stored in the non-volatile memory (), from a data provision device () connected with the data carrier (). If the requested data are obtained from the data provision device (), the data carrier () determines whether the obtained data are stored in the non-volatile memory () of the data carrier () for the response to future data request messages.
