*“The future Internet of Things links uniquely identifiable things to their virtual representations in the Internet containing or linking to additional information on their identity, status, location or any other business, social or privately relevant information

* at a financial or non-financial pay-off that exceeds the efforts of information provisioning and offers information access to non-predefined participants.

* The provided accurate and appropriate information may be accessed in the right quantity and condition, at the right time and place at the right price.

* The Internet of Things is not synonymous with ubiquitous / pervasive computing, the Internet Protocol (IP), communication technology, embedded devices, its applications, the Internet of People or the Intranet / Extranet of Things, yet it combines aspects and technologies of all of these approaches.”

*Reader CANNOT read all tags at all times

*Readers need coordination within a limited

physical space, like a warehouse or a plant,

because of limited channels and bandwidth.

*Real world objects and people can interfere

with RFID communications

*Towards the Internet of Things

* RFID allows things and places in the physical world to automatically generate data for information systems

*RFID is a set of technologies

* No “one-size-fit-all” tag and reader

* All readers cannot read all tags at all times

* Physical layout matters

*RFID security challenges

* All readers should not read all tags at all times

* Trade-offs have to be carefully considered

*

Looking ahead…
