Contactless automatic RFID system is intended to replace existing barcode scheme, since it has the capability of reading huge amount of data from many tags simultaneously in a respective range. Whereas, an RFID system is consist of a database server connected with many readers through wired communication and readers to tags are mostly wireless communication. This wireless connection in between tags and readers are vulnerable by an adversary in many ways. However, there are some common problems in RFID system such as: location tracking, bogus request, indistinguishability, spoofing and forward security.
