SWP switch?

[lees.lee]

Puzzled for a while for one master (reader) connect to two security elements through SWP.

Q: Is that possible have a switch control by GPIO so the reader can talk to either ONE security elements on the system depend GPIO setting?

I don't understand your question - it is too vague.

'GPIO' could be a microcontroller port - is it? And there are dozens of definitions for 'SWP'.

What do you mean, exactly?
