This project aims to develop a smart system to identify stolen cars at checkpoints using radio frequency identification (RFID) technology. The system involves issuing each car a unique identification code stored on a silicon chip installed under the vehicle. When a car passes a checkpoint, a passive RFID reader will generate a 125 kHz frequency to read the chip's ID code. If the code is not in the system's database, the car would be identified as stolen. The key components used are an RFID reader, microcontroller, LCD display, LEDs, and EEPROM memory. The system works by encoding each car's unique ID number and storing it on an RFID tag installed on the car.

3. Introduction
• This project is developing a smart logic to
identify the stolen car on check post.
• we issue one unique identification code to
every car.
• unique number is stored in the silicon chip
and installed under the car.
• If passive card reader generates a 125 kHz
frequency.

4. What Is Uid & Code..!!
• (UID)… is a global asset tracking system for hard
products. UID tracking ensures asset location.
• Code Format…Tags contain barcode and human-
recognition information with specific data formats,
including an approved enterprise-specific code,
unique serial number, and the original serial number
if serialized.
• IRFID tag… is a microchip combined with an antenna
in a compact package.

14. Remote Control
• For remote control (IR) we have used Holtek
encoder-decoder pair of HT12E and HT12D .
• RF as well as IR principles. Both of these are
18pin DIP Ics.
• HT12E and HT12D are CMOS ICs with working
voltage ranging from 2.4V to 12V.
• Encoder HT12E has eight address and another
four address/data lines.

20. Infra Red frequency Identification
• product, animal, or person for the purpose of
identification and tracking using radio waves.

21. I.R.F.I.d Application ..!!
• IRID tags used in libraries: square book tag,
round CD/DVD tag and rectangular .
• Hand with the planned location of the IRID chip.
• Just after the operation to insert the IRID tag
was completed

22. Barcode: Introduction
• Barcode, in its simplest form, is a set of bars
and spaces representing alphabet or numeric
data for identification of a particular product,
service or a process.
• identification or “Auto ID” the automatic
recognition and recording of data.

23. Barcode Technology
• Thousand of retail stores around the world, and a
rapidly increasing number in India use bar codes
to collect information at the checkout.
• On its packaging each product carries a barcode
which uniquely identifies.
• . A Barcode system, typically, consists of three
components :-
• 1-origin(source of barcodes),.. 2-reader(scanner
or a data terminal),.. 3-computer system(Finally, a
barcode system )….

24. Barcode Marks..
• Bjjjjjjjjjkklllllllllllllllllll Retail
• Kkkkkkkkkkkkkkkkk Trade & Logistics
• Health Care

25. Infra-red Emitting Diodes
. IRFID sensor use with two Ics in emitting diodes.
L-53F3C L-53SF4C
• L-53F3BT L-53SF4BT
• made with gallium arsenide infrared emitting
diodes.
• gallium arsenide is a direct-gap semiconductor
with an energy gap of 1.4ev at room
temperature. a typical gaps led is made by solid-
state impurity diffusion.

26. Conclusion..!!
• Still there is no technique to identify the car
on check posts by any mean. Logic behind this
project is developing a smart logic to identify
the stolen car.
