Towards EPC Compatible Plastic RFID Tags

摘要

One of the main drivers for the development of organic thin film transistors are low-cost radio-frequency identification (RFID) tags. RFID is a widespread technology in logistics, automation, identification, and others. It allows for transmission of an identification code in the memory of the transponder chip via radio waves from a transponder to a reader without the need for line of sight. Item-level tagging is potentially a large market for organic RFID tags. Reasons are essentially that the transponder chip (or code generator) made in an organic technology can be significantly lower in cost than with silicon. Indeed, organic technologies are applied at low temperature (little energy), directly on mechanically flexible and low-cost substrates (low-cost chip handling) and at high processing speeds (resulting in lower cost-of-ownership of fabs). However, to succeed in the marketplace, those plastic RFID tags need to be not only lower cost as passive Si-tags, but also - as importantly - still be able to comply with the established standards, particularly the standards for item-level tagging..
