RFID for newbies, sauce security

There is not a single day where we do not use RFID.Radio Frequency Identification (RFID) is indeed a pervasive technology deployed in many applications to identify or authenticate objects and subjects with neither physical nor visual contact. As illustrated on Figure 1, an RFID system usually consists of tags, i.e., a microcircuit with an antenna, carried by the object or subject, some readers that allow to remotely query the tags, and a back-end system that can be centralized or distributed into the reader(s).
