protocol type selection (PTS)

In the Answer to Reset (ATR) communication between a smart card terminal and a smart card, the terminal can then send a PTS request, Protocol Type Selection, to the smart card if the terminal wants to use other parameters or if the software needs to be updated. Such a PTS request can be accepted by the smart card or it remains unanswered. If an update is required, the smartcard acknowledges the corresponding PTS request, if it is not required, the smartcard communication with the smartcard application continues.
