asterisk users - Sep 2005 - system() app changed drastically! How do I use itnow?

Try the following:

exten => s,1,Answer
exten => s,2,Wait(1)
exten => s,3,Read(PIN,87)
exten => s,4,System(/usr/local/bin/pin -c ${PIN}) ; check it 
exten => s,5,System(/usr/local/bin/pin -d ${PIN}) ; delete it 
Exten => s,6,GotoIf($[${SYSTEMSTATUS} = FAILURE]?105:7)
exten => s,7,SetAccount(${PIN})
exten => s,8,Newt,pinout-config  ; connect them
exten => s,105,Playback(5021)	 ; tell them their PIN is invalid
