Abstract

The invention relates to a method on a portable data carrier (10). In said method, a web server (62) of the data carrier (10) preferably receives command information from a terminal (100) connected to the data carrier (10), the command information relating to at least one CAT command (“Card Application Toolkit” command). The at least one CAT command is then executed by a CAT interpreter (64) of the data carrier (10). The command information is embedded in an HTTP command request message of an HTTP client (110) of the terminal (100), and the web server (62) extracts the embedded command information from the HTTP command request message before relaying it to the CAT interpreter (64) of the data carrier (10) for execution of the at least one CAT command. In this manner there is enabled a flexible and resource-saving interaction between the web server (62) and the CAT interpreter (64).
