Abstract

The invention proposes a smart card which comprises a digital signal processing receiver that can automatically identify the type of a smart card reader based on the error vector magnitude of signals received from the reader. The digital signal processing receiver is able to reconfigure itself at runtime in order to optimally minimize its power consumption in dependence on the type of reader it is communicating with. Furthermore, the invention proposes a new preamble structure that comprises a basic part and an optional additional part.
