FID would have remained a nicheechnology if it was not for Moore's lawnd the ability of the semiconductorndustry to produce chips that packagerocessing power at a level that makes.t affordable for the mass RFID market

vv Broadband wired and wireless networks and

cheaper edge processing servers he availability of pervasive broadband data,etworks coupled with affordable yet,owerful servers has led to the developmentf architectures that move processing to .here the business processes are carried out

v Edge processing capabil ity dge processing capability derives from having-owerful yet low cost personal computers andervers deployed at the edges of thenterprise network as well as a broadband.onnection to the data center

v Service-oriented architecture -ervice oriented architectures allow us to-evelop and deploy loosely coupled moduleshat interface with each other using web- .ervices based standards he overall RFID system architecture followshe principles widely accepted today as the

D and the serial number is created by UDC D Center established universities andompanies hope was that they could developtandards that would reduce the cost ofndividual tags the component and thattandard identifiers could facilitate- .nformation sharing among industry partners ,e can and some bar code encoding systems are

.lready being used to make RFID tags ncoding identities on RF tags

,ach type of identification tag from barodes and optical scatter codes to magnetic,tripes and RFID tags has a particularncoding that allows it to represent an.dentity f the identity only needs to be read by the,utomated system print the identity in a)orm that it can read very easily ex barcode

n order to select the proper encoding to,rite an identity to an RFID tag you mustnow both the type of identity you want torite and the memory capacity and type of. )he tag itself ex GID encoding

- -ar codes are often applied using print andpply machines that press or blow an adhesiveag onto an item as it passes by on an,ssembly line and similar devices exist for.mart label RFID tags ne important consideration when weighing theost of adopting an automated method forttaching smart labels is the relatively highefect rate of these RFID tags due to their.elicacy and sensitivity

Motivations for using RFID middleware :ia the reader adapter providing connectivity with.eaders :ia the event manager processing raw RFID .bservations for consumption by applications -roviding an application level interface to manage.eaders and capture filtered RFID events

The reader adapter ,eader interfaces as well as data access and device, ,anagement capabilities differ widely so youhould try to use middleware that shields you fromaving to learn the idiosyncrasies of individual.eaders he reader adapter layer encapsulates the proprietaryeader interfaces so that they don't come in

.ontact with the application developers The event manager

-ost of these observations would be too fine grained,o be meaningful to applications so you want toncapsulate the reader interface to keep the .pplications from being bombarded by raw data -nterprises will thus need to deploy special purposeFID middleware near the edges of their IT.nfrastructures n RFID event manager aggregates raw RF read data( )rom multiple data sources such as readers andonsolidates and filters it based on previously- .onfigured application level event filters ost event managers then feed the filtered data to.he backend systems

The application-level interface -he application level interface is the top.ayer in the RFID middleware stack ts primary purpose is to provide atandardized mechanism that enablespplications to register for and receive

iltered RFID events from a set of.eaders -he application level interface also ,rovides a standard API for configuring,onitoring and managing RFID middleware.nd the readers and sensors it controls

hile you're defining the business requirements and,apturing functional requirements pay careful .ttention to accounting for exception processingv Don't Forget Your Existing Infrastructure

,ore often than not RFID systems will have to coexist, ,ith bar code systems providing alternate more.utomated capabilitiesv Process Data at the Edge Where Possible

.rocess as much data as possible at its source he raw RFID observations collected by readers shoulde filtered at the edge before sending only what is

.eaningful to applicationsv Track Items to the Level Your Business Processes Wil lSupport
