The rest of the coding and synching for the Account Section are as follows:

• Business Scenario of implementing RFID (everyone is using it; almost become standard, etc.)

RFID Overview

• Radio Frequency Identification (RFID)

• RFID is simply an enhanced barcode that can be read from a distance.

• Passive RFID most used is 915Mhz frequency range.

• The Wal-Mart, Target, Best Buy,

Albertsons, and the Department of Defense are examples of users of this most basic form of RFID technology.

RFID Overview

The current standards are:

•Class 0 (read only) •Class 1 (read-write)•Class 0+ (Matrics)•Generation II

RFID Process

flash

RFID in Distribution Center

• The advantage of RFID: It is always looking for RFID tags.

• It watches for tags to move through a dock door and report the information about the product movement.

• RFID helps ensure an accurate product shipment count.

Accuracy Count

• As cartons are being palletized, a pallet tag is created.

• RFID reader scans pallet tag for a list of carton tags.

• As each carton move through the dock door, RFID scan the carton tag and compare it with the list.

• It shows “green” light if the carton is on the list, or “red” light if it’s not.

Impact on Business Operations

• Safety and security• Mobile asset management • Complex process simplification

Safety and Security• Reduction or elimination of theft

• Tracked and traced

• Applied to important, sensitive or valuable documents

• Human security

Mobile Asset Management

• Millions of dollars invested in mobile/moveable assets

• Thousands of mobile assets moving through daily

Complex Process Simplification

• Lengthy "chain of custody”

• Updated with history every step in the process

• Greatly simplify the process.

Security in RFID systems

• Forgery of tags

• Unwanted tracking of customers

• Unauthorized access to the tag’s memory

• Solution: Authentication

Security Authentication

• A communication system providing authentication can reject access to non authorized parties.

• Security gates can query the ILS (Intelligent Library System) to determine its security status

• Tag may contain a security bit which would be turned on and off by circulation or self-check reader stations.

Passive RFID Tags• “Traditional” tags

– Tag = antenna(detect signal) + chip(store data)

– programmed at manufacture / on installation– powered by the high power electromagnetic

field generated by the antennas – chip/antenna reflect back an extremely weak

signal containing the data– Collision Detection – recognition of multiple

tags in the read range to read individual tags

• If manufactured in billions, tags will come down in price from $0.80 to $0.05 in the next 2 years.

Active Tags

• Battery Powered tags– Have much greater range – 100m– Hold much more information – Kbytes– Can integrate sensing technology

• Temperature, GPS

– Can signal at defined time– Multiple tags can be recorded at once

• Used for higher value items– Electronic

• Cost between $20 and $40 per item• Life between 2 – 4 years

RFID Handheld Reader

• read and write to tags & smart labels

• provides an easy migration path from bar codes to RFID tags

• available with a variety of interfaces for simple connection to any host

• cost-effective product ($ 500)• lightweight and durable• great look and feel• for healthcare & commercial

applications

RFID Reader + Antenna

• Extended read range• High data rates• Large number of tags

reading• High sensitivity• Software configurable

to read/write tags• Circular/linear Polarized

Antenna• Price: $ 3399

Multi-Protocol Printer/Encoders for RFID Tags

• 4-inch Bar code label printing

• Flexibility in tag placement

• Statistics tracking of number of goods

• Eliminates costs

• Price: $ 4995
