What is RFID?

Radio Frequency IdentificationThe use of radio frequency tags toidentify real objects.

What does it mean to identify something?



Identification

Assign IDs to objectsLink the ID to additional informationabout the objectLink the ID to complementary infoFind similar objects



Identification Examples

Bar CodesLicense PlatesSocial Security NumbersStudent ID

Serial NumbersCar KeysDatabase Keys



How Does RFID Work?

3 ComponentsTransceiver – Tag Reader Transponder – RFID tagAntenna



RFID Hardware

Magnetic / Inductive Coupling

Transceiver Tag Reader

antenna

RFIDTag

IC or microprocessor

antenna



Types of Tags

Passive TagsNo batteryLow cost

Active TagsOn-board transceiver Battery – must be replacedLonger rangeHigh cost



Comparison of Active vs. Passive Tags

Feature Active Tag Passive Tag

Frequency 420-450 Mhz, 63.57 Mhz (Versus) 125Khz, 13.56Mhz, 920-930Mhz, 2.4-5.8Ghz

Typical usage Position tracking, location-based computing, “Aware” systems that canreact to specified physical signals and stimuli

Object identification, process automation,Retail

Typical environment Hospitals and healthcare facilities, Warehouses & Freight managementfacilities, Defense and high-security installations

Retail sales, Warehouse and freightmanagement, Logistics, Manufacturing &Supply chain management, Agriculture

Range 1 - 100 m 2 - 50 cm

Cost Medium, Re-usable for long-term cost recovery Low, but non-reusable tags



Types of Tags

Read Onlyfactory programmedusually chipless

Read / Writeon-board memorycan save datacan change IDhigher cost



Real Tags



Data Transfer

Amplitude Modulation (AM)Frequency Shift Keying (FSK)Phase Shift Keying (PSK)



Phase Shift Keying

One frequencyChange the phase on the transition between

a 0 to 1 or 1 to 0Faster data rate than FSKNoise immunity

Slightly more difficult to build a reader than FSK



Data Encoding



Multiple Tags?

What happens when multiple tags arein range of the transceiver?

All the tags will be excited at the sametime.Makes it very difficult to distinguishbetween the tags.



Collision Avoidance

Similar to network collision avoidanceProbabilistic

Tags return at random times

DeterministicReader searches for specific tags



Frequency Ranges

Low – 100-500 kHzshort range, low data rate, cost, & power

Intermediate – 10-16 MHzmedium range and data rate

High – 850-950 MHz & 2.4-5.8GHzlarge range, high cost, high data rateneeds line of sight

The optical nature of barcode requires labels to be "seen" by lasers. That line-of-sightbetween

label and reader is often difficult, impractical, or even impossible to achieve in industrialenvironments. In order to function properly, a barcode reader must have clean, clear optics,the label must be clean and free of abrasion, and the reader and label must be properly

oriented with respect to each other. RFID technology enables tag reading from a greater distance, even in harsh environments.

In addition, the information imprinted on a barcode is fixed and cannot be changed. RFIDtags,

on the other hand, have electronic memory similar to what is in your computer or digitalcamera

to store information about the inventory or equipment. This information can be dynamicallyupdated.

The Advantages of RFID over barcode technology:- No line of sight requirement.- The tag can stand a harsh environment.

- Long read range- Portable database Multiple tag read/write.

RFID Benefits Vs. Barcode



Who’s got an RFID tag withthem right now?



Security

RFID used to grant entry to secureareas

Tracks time and movement of peopleDynamically change access codesProvide automated entry



Live Jewellery stock Tagging

RFID Tag for Jewelry



Tracking Animals & Birds



Automated Toll Collection



Package Tracking



Jewellery Store

Every item in the store already has abar code.

Why not use an RFID tag?Speed up checkouts



Smart Jewellery Store

Faster TrackingBulk Invoicing

How much docashiers cost?



Smart Grocery Store

Add an RFID tag toall items in the

grocery.As the cart leavesthe store, it passesthrough an RFID

transceiver The cart is rung upin seconds.



Groceries Enhanced

Track productsthrough their

entire lifetime.



Fridge

Recognizes what’s been put in itRecognizes when things are removedCreates automatic shopping listsNotifies you when things are past their expiration



RFID’s Advantages
