Claim:
A method in a portable data carrier having a web server, comprising the steps: receiving a data request message from a data processing device connected with the data carrier by the web server of the data carrier, wherein the data request message relates to a provision of data for the data processing device; responding to the data request message by causing the web server to send a data provision message comprising the requested data to the data processing device, wherein the data are read out from a non-volatile memory of the data carrier or, if the data are not stored in the non-volatile memory, are obtained from a data provision device connected with the data carrier; wherein, if the requested data are obtained from the data provision device, the data carrier determines whether the obtained data are to be stored in the non-volatile memory of the data carrier, wherein the data carrier is a chip card or a USB token, wherein the data carrier determines on the basis of a storage criterion, which relates to the size of a buffer memory in a volatile memory of the data carrier, whether the data are stored in the non-volatile memory of the data carrier.
