Radio Frequency Identification (RFID) is a technology that uses electronic tags to uniquely identify items or people. You likely use RFID every day without even realizing it. This presentation discusses the various types of RFID technologies and its use in practice.
Dr. David Carta, CEO of Telaeris, has spoken at numerous events about the benefits, problems, and capabilities of RFID. With more than 25 years of experience with RFID, he enjoys speaking both about practical applications as well as technical details.

11. Two Main Classes of RFID
Active
•Battery powered memory,
radio & circuitry
Passive
•Tag powered from
collected reader energy
12.
13. • Lanyards
• Zip-Tie
• Epoxy Mount
• VHB Tape
• Weld Tabs
• Rivetable
• Boltable
RFID Tag mounting options fit a
wide range of applications
14. RFID Benefits
1. Can uniquely identify individual item
2. Reads through dirt, paper, or
stickers
3. Read distance can be cm - km
4. Can read and write data to tag
5. Can store kilobytes of data
6. Can make counterfeiting difficult
7. Increased operational efficiency
May not get all of this in one tag!

16. RFID Frequencies
118 KHz to 148 KHz (LF)
• Animal Tagging,
Access Control
• Range – inches
to several feet
• Well adaptable
to metal
environments
• Inductive
25. RFID For Product ID
Uniquely Identify the Product
01.0000B45.002CFE.000034526
ELECTRONIC PRODUCT CODE
1. Bits (00-07) - Header
2. Bits (08-35) – EPC Manager
3. Bits (36-59) – Object Class
4. Bits (60-95) – Serial Number
Barcodes identify the
manufacturer and type
of product only
“Squiggle Tag”
EPC Gen2 RFID identifies
the item uniquely,
including manufacturer
and product type
40. RFID Frequencies
Active (433 MHz - 2.45 GHz)
• Active Tags – Battery powered
• Higher tag cost
• 10 meters to 1 km
• 5 year lifetime
• Works in and around metal
• Highway tagging
• RTLS and GPS Capable….sometimes
• Asset tracking
• Hospital Tracking
• Vehicle tracking
57. RFID Is A Tool - Not A Solution
• Used for identification and
authentication
• Allows mobile data object to be
attached to an inventory item for
immediate read
• Good for reading at a distance and
reading multiple tags quickly.
• Requires significant backend database
for access and use of item information
• System/solution is of paramount
importance
58. RFID System Disadvantages
• Subject to interference – can be tricky
• Security Issues – easily spoofed
• Incorrect Tag Reading
• Orientation Issues
• High cost…compared to printed serial no.
• Environmental damage (force, heat,
pressure)
• Damage from abuse
• Cost of encoding
• Cannot specify which tag is to be read
59. RFID Can Improve Your
Operations and Help you
be more Profitable
But First Understand the
Problem you think it will
solve for you.
