+\begin{frame}{SIMtrace2 {\em card emulation} / {\em remote SIM}}
+\begin{itemize}
+	\item The SIMtrace2 hardware can emulate the physical SIM card interface
+	\item This means that SIMtrace2 is connected to SIM {\em instead} of a SIM
+	\item The communication is picked up and passed via USB to the host
+	\item Host can now, for example, forward this communication to a (remote) smart card reader with the actual SIM
+	\begin{itemize}
+		\item {\tt simtrace2-cardem-pcsc} is a simplistic implementation of that: Pass communication to a locally connected PC/SC compatible reader
+		\item The {\tt osmo-remsim} software suite is a comprehensive software package for managing a fleet of phones/modems and SIM cards, allowing dynamic assignment of remote SIMS to phones/modems.
+		\item See a previous OsmoDevCall
+			(\url{https://media.ccc.de/v/osmodevcall-20210827-laforge-osmo-remsim}) for a talk on that
