Origins
Radio Frequency IDUsed on a primitive level since WWIIFirst circuits incorporated in 1970sIn widespread use since late 80s
Used in several applicationsAirplane TranspondersAutomatic Tolling SystemsAnimal TrackingStore Anti-theft System

Active vs. Passive RFID Tags Active tags in widespread
usage Transmit a signal, have
internal logic Typically found on more
valuable objects Prohibitively expensive
for small items

Active vs. Passive RFID Tags Passive tags
No power-source Cheaper, but less
data capacity Short read range

RFID Readers/Scanners
Examples of various RFID scanning devices

RFID for the Supply Chain
RFID tags superior to UPC barcodesCan be read from a distance
• Less manual work requiredMultiple tags can be read at onceStore more information
“EPC” Electronic Product CodeMore descriptive than UPC
• Can describe an individual item, not just productLinked to the internet

Important Players

Problem Statement
Raw Data Not easily human-readable Useless without context Far more information than a tracking
application requires Can contain inaccuracies
EPC Tags Useless without product info Product information must be consistent
through the supply chain

Problem Statement
RFID vs. UPC/BarcodingNot useful as a simple substituteOnly becomes valuable when used with
computer automationExtra data available from EPCs
requires a network of EPC dataHas the possibility to be much faster
and more informative than UPCs, but will not be with hardware alone

Goals + Objectives
Produce small tracking application for an RFID-enabled building complex
Alpha data will simulate data from application interfaces
Will require a backend interface Application has simple GUI

Obstacles + Risks
TimeNot Enough
Not a well-developed sector yetSolutions are still fairly proprietaryDeveloped primarily in-house by clients
DocumentationNot a great volumeDifficult to sort through, highly technical
