Use this command to perform a proximity check in order to verify if the transponder is within the
proximity of the reader. This helps you to secure the reader from relay attacks. Depending on the
configuration of the transponder, proximity check might even be mandatory before any login can take
place. Note that only Mifare® PLUS X transponders support proximity check.
