2. In this talk... What is RFID What it can look like My method
Why it is important
Applications
Summary

3. What is RFID? Radio Frequency Identification Been around since WWII
Most people use it everyday and don’t realize it
Consists of
RFID middleware, reader, antenna, and tagged item
Mostly used today for keeping track of any physical item, digitally

4. What is RFID?
It allows for any item to be tracked by a small radio device
The system is comprised of devices
Tags
Cards
Readers
Sensors
PDAs

5. Tags Each tag has a unique ID Tags can be passive or active Passive
Passive tags use the readers radio waves to power itself and activate
Can send up to 128 bytes of information
Small range
Up to 20 year life span
Passive tag

6. Tags Active tags Are powered by a battery
Always on and have a large range
Up to 128 kb of complex information
5-10 year life span
Active tag

7. Tags Appearance Buttons Discs Cards Labels Capsules PIT tags
Passive integrated transponder
Used for small animals

8. Readers/antenna Collects/sends signals from nearby tags
At certain frequency
Depending on the size and shape of the antenna
Whenever a tag is in range, the signal is sent back
Sometimes modulated with the tag ID
Inductive coupling

9. Readers
Examples
Toll ways
Forklifts
Shelves
Handheld
Handmade boards

10. Readers/ antennas
The readers send information to the computer via USB or SD

11. RFID middleware/software
Arduino software
Just download from website
From this you can operate the board
Make changes to the RFID code
For homemade boards

12. Tracking bird patterns
Field work
Capture of a bird to tag them
Bird feeder/home set up
DIY
Reader and antenna set up
Portable battery for board

13. Set up Once the components are set Wait for the birds
Let the data collect
Once waited for as long as you want
Take the device out of the bird feeder
Connect to your computer

14. Set up Once launched onto your computer
Read the logs that the reader recorded
Down to the exact time of arrival
The board has a clock
The log is specific and unique for each tag
This lets you track individual birds

15. Effective range
Range depends on the frequency and thickness of the antenna coil
Measured the range with a ruler
Found it was about 1.5 cm all around the antenna
Except for when the tag was parallel to the antenna
There was no range

16. Effective range

17. Effective range The range for the antenna I used was small (125 kHz)
Because range depends on the inductance of the coils
Low frequency: 125 kHz kHz
Range: centimeters
High frequency: MHz
Range: up to 1 meter
Ultra high frequency: 433, and 860 MHz MHz
Range: up to 50 feet

18. Frequency uses Low frequency is used for: Animal tracking
Access control
High frequency:
Library tracking, patient tracking, transit tickets
Ultra high frequency:
toll ways, warehouse docks, races

19. Why RFID is important Enable tracking for any items
Allows businesses to digitally sort and file
Creates opportunities for further advancements
Components are cheap
Technology is simple to learn

20. Why RFID is important Anyone can find it useful DIY projects
Animal tracking
The tags are small enough to track smaller animals
Alternate for GPS tracking
Discover more about animal patterns/behaviors

21. Other applications Shipping Track packages Sort Retail Prevent theft
Smart cards
Smart storage

22. Other applications Healthcare Patient ID wristband Tollways
Pet feeders
Key fobs

23. Other applications Vehicle tracking Schools and universities
Museums and galleries
libraries
Military
Farms
Trains

24. Growth Cheaper materials Advance in technology
Many businesses starting to apply RFID
Ease of adapting to smarter technology

25. Future uses Connecting to the cloud Larger, more complex information
Defending privacy concerns

26. Summary
RFID uses radio frequencies to track and communicate with physical item
RFID has been around for a long time
Tags can be put on or integrated into most items
Tags can be passive or active
With varying ranges and uses
Readers send and receive radio waves with the tags

27. Summary RFID is a great tool to learn about animal patterns
Especially smaller animals
RFID is already all around us in various industries
Materials are cheap and can be homemade
Doesn’t take a lot of physics knowledge to use
Keeps businesses and the world organized
Makes tracking many items at a time easy
