Abstract
The present invention relates to the field of short-rage communication systems. In particular, the present invention relates to radio frequency identification transponders with fixed physical memory capacity having however a flexible virtual memory capacity allowing for providing amounts of data by the radio frequency identification transponders extending the fixed physical memory capacity. Accordingly, a method and a radio frequency identification transponder for continuos data provision by a radio frequency identification transponder is provided. A stream of data is received via a data interface for the transponder and the received data is stored in a transponder memory. Then the stored data is read out form the transponder memory and supplied to a radio frequency interface for being communicated therewith. Next, the memory, which is currently used for storing data, which has been read out previously, is provided afterwards for storing data being received subsequently via the data interface.
