What is Singulation

Mass deployment of radio-frequency identification (RFID) technology is now becoming feasible for a wide variety of applications ranging from medical to supply chain and retail environments. Its main draw-back until recently was high production costs, which are now becoming lower and acceptable. But due to inherent constraints of RFID technology (in terms of limited power and computational resources) these devices are the subject of intensive research on how to support and improve increasing demands for security and privacy. This chapter therefore focuses on security and privacy issues by giving a general overview of the field, the principles, the current state of the art, and future trends. An improvement in the field of security and privacy solutions for this kind of wireless communications is described as well.
