-====== ReinerSCT RFID basis reader ======
+====== Taking apart the ReinerSCT nPA RFID Basisreader ======
 The ReinerSCT basis reader is a pretty basic reader for mifare cards and the new german ident-card (ePA or nPA).
-It was sold with german computer-magazine ComputerBild 26/2010 for €3,70 instead of the initial €34,90. It comes with a OWOK rfid card.

 There is a [[http://www.mikrocontroller.net/topic/199865|thread]] on german µC-related forums [[http://www.mikrocontroller.net/|Mikrocontroller.net]] discussing the hackability of this reader as well.
