2. Abstract
 Automatic Toll collection system uses RFID
technology.
 RFID based automatic Toll collection system
provides paperless passage of Toll gates with fully
automated Toll collection.
 They help in reducing Toll gate traffic and
avoid illegal passage of vehicles through a Toll
gate.

3. Objective
 Reduce longer waiting
time in a toll queue.
 Provide traveler ease of
Toll payment.
 Reduce illegal Toll gate
entry.

4. RFID
 Radio-frequency
identification (RFID)
wireless non-contact use
of radio-frequency
electromagnetic fields to
transfer data.
 Tracking tags attached to
objects.
 Tags contain
electronically stored
information.

5. RFID – Passive Vs Active tags
Passive Tags
 Reader provides
operating power.
 Shorter read range
(10 cm – 5 meters)
 Can last over 10 years.
Active Tags
 On-board power
source.
 Long read range
(100 meters)
 Can last generally from
2 to 7 years.

6. Data Acquisition
 RFID tags are intelligent bar codes that can talk to a
networked system to track every product you attach.
Tags Host ComputerAntenna Reader

7. Continued…..
 They consist of a tiny processor, memory, and
antenna.
 RFID tags can be read and written wirelessly.
 Vary in complexity and cost based upon frequency,
memory, sensor integration, size, antenna, and
power.

8. Problems in Barcodes
• Transmission of data is performed optically-clear
line of sight required.
• Information storage is limited.
• Read only one tag at a time.
• Read capability can be affected by dirt, water and
scuffing.
• Reduced security.

9. Need for RFID
• Communicates through radio waves, line of sight
not required.
• RFID tags store significantly more information.
• RFID is dynamic and information can be added or
deleted at every step in the supply chain.
• Increased functionality: covert and difficult to
counterfeit.
• Read multiple tags at once.

11. Working
 As a car approaches a toll plaza, the radio-
frequency (RF) field emitted from the antenna
activates the transponder.
 The transponder broadcasts a basic information to
the central database.
 If the account is in good standing, a toll is
deducted from the driver's prepaid account.
 A green light indicates that the driver can proceed.

14. Advantages
 Entire process takes a
matter of seconds to
complete.
 Electronic system
records transaction,
including the time, date,
plaza and toll charge of
each vehicle.
 Allow drivers to pass
through the system at 55
miles per hour (88 kph).
