 PROGRESS REPORT
 DESIGN

• New Delhi: ICICI Bank, launched the ‘Smart Vault’, a fully automated locker
available 24x7, including weekends and post banking hours.
• The ‘Smart Vault’ uses robotic technology to access the lockers from the safe
vault and enables customers to conveniently access their lockers at any time
of their preference, in the comfort of a secure lounge where the locker
automatically comes up to the customer.
• Customers can access the lockers in total privacy without any intervention of
the branch staff. Located at New Delhi, the ‘Smart Vault’ is equipped with multi-
layered security systems including biometric authentication, debit card & PIN
authentication, unique dimple keys that are difficult to replicate, unbreakable
lock system and the option of using additional personal lock as well.
• We named our project after our source of Motivation.
MOTIVATION

 In this era, with the increase of wealth and valuable assets develops a need to protect
it from being stolen or misplaced. To protect and place our belongings in a safe place is
always what we desire. Through the years this has led to the development of vaults
that are locked by locks that the greatest mind are not able to decode. But still there is
a constant fear of our valuables being stolen.
 The primary objective of our entire project is to develop a security system which the
users can access at any time of the day or night. The security of the system is enhanced
by using three tiers of security which includes the biometrics system which takes in the
fingerprint of the user, the unique plastic card which each user of the security system
possesses and a 4 digit password which may be uniquely set by the user on creating
his/her account. Further, the system is made available 24x7 by totally automated
security system which involves no human intervention.

PROGRESS CHART

 In need for strengthening the security system and in order to eliminate the
disadvantages of the traditional vault system, we had to totally come up with an all-
new design which incorporates three levels of the security system and a carousel
which exposes only one vault at a time.
 We designed our model in such a way that security is always considered our first
priority. So to enhance the security system we incorporated three tiers of security
level namely:
1. Fingerprint Module
2. RFID Card Reader Module
3. 4 digit password
DESIGN

 When all the three levels of security are checked the vaults have to be placed at a fixed
locations from where the users can assess their valuables. Various designs were considered
to make this happen.
Robotic Arm
Conveyor Belt
Circular rotating carousel
 Fixed time intervals
Fixed angles
 IR Sensors

• Ceramic capacitors C1 & C2
(both of 33pF) and crystal
X1(12 MHz) is related to the
clock circuitry which
produces the system clock
frequency

• The keys are connected in simple parallel
manner.
• In order to save a few pins the keypad can
also be connected in a matrix form of 5x2 or
so.
• 10 Push button switches for 4 digit password
(0-9) are connected to the D0, C0,
C1,C2,C3,C4,D2,C5,C4,D3 & D1 bits of the
microcontroller, configured as input pins.
• Each of these is connected to a pull up
resistor such that this pin is at Vcc potential
when the switch is not pressed.
• When the switch is pressed the pin it is
connected to will be grounded.
• The resistor is connected in series with it to
limit the current.

• The interface between this LCD and
Microcontroller can be 8 bit or 4 bit.
• Since the 2X16 character LCD is
connected in a 4 bit mode to the
microcontroller, it makes use of only the
lower 4 data lines i.e. D4, D5, D6 & D7
which are connected to B5, B4. B3 & B2
respectively. The RS (Register Select) &
EN (Enable) bit of the LCD is connected to
the B7 & B6 of the processor
respectively.
• R/W pin is meant for selecting between
read and write modes.

 The fingerprint sensor is combination of R305 FP+PIC MCU board that can read different
fingerprints and store in its own flash memory.
 The sensor can perform three functions namely Add (Enroll), Empty Database or Search
Database and return the ID of stored fingerprint. Any of three functions can be called
simply by making the pin low of the sensor or pressing on-board three switches.
 The response is either ERROR or OK which is indicated by on-board LED. The response is
also returned as single serial data byte.
 The return byte is a valid ID or error code. The response byte is a single byte at 9600 bps
thus making whole sensor very easy to use.
 There are 6 pins on the R305 Fingerprint Module namely GND, +5V, TX out, search, empty
and add connected to the pins GND,+5V, one of the inputs to one of the OR gate, D4, D5 &
D6 of the microcontroller respectively.

Types of functions performed by R305 module
Add (Enrol) Function:
Adds a fingerprint to
database and return a
byte of newly added ID.
Return values are from
0x00 to 0xFE. In case of
error like no finger
placed, return code is
0xFF. Here 0xFF means
error executing function
Search Function: When
a finger is put and
search function is called,
it returns a matching ID
if found in its existing
memory. Return values
are from 0x00 to 0xFE.
In case of error like no
finger placed, return
code is 0xFF. Here 0xFF
means error executing
function.
Empty Function: When
you wish to empty all
fingerprint data stored
on sensor you can use
this function. After
executing this function,
you will get 0xCC as OK
or 0xFF in case of error

The EM-18 RFID Reader module generates and
radiates RF Carrier Signals of frequency 125 KHz
through its coils. When a 125 KHz Passive RFID
Tag (has no battery) is brought in to this field, gets
energized from it. These RFID Tags are usually
made using a CMOS IC EM4102. It gets enough
power and master clock for its operations from the
electromagnetic fields produced by RFID Reader.
By changing the modulation current through the
coils, tag will send back the information contained
in the factory programmed memory array.
EM-18 RFID Reader
Module can be directly
interfaced with 5V PIC
Microcontrollers using
UART module When a
RFID Tag is bring in to the
field of EM-18 RFID
Reader, it will read its tag
number and give output
via TX terminal. The BEEP
terminal will become LOW
to indicate valid tag
detection.
The UART output will be
12 ASCII data, among
these first 10 will be tag
number and last 2 will be
XOR result of the tag
number which can be
used for error testing.
For eg : If the RFID tag number is 500097892E, output of EM-
18 Reader will be 500097892E60 where 60 is 50 xor 00 xor 97
xor 89 xor 2E.
There are 3 pins of the EM18 RFID Module
namely GND, +5V & TX output which are
connected to ground, Vcc and one of the
inputs to other OR gate.

Two OR gates and one AND gate is used to
sync the system in such a way that the user
gets access if BOTH the fingerprint and the
RFID card matches and also because there is
just one RX pin. The Fingerprint Select pin is
E0 and the RFID Select pin is the A5 pin of the
PIC. The TX of both the FP & RF are fed as
one of the inputs of the OR gate and the other
input is the respective Select pin. The output of
the two OR gate is combined using an AND
gate and the output of the AND gate is fed to
the RX (C7) pin of the Microcontroller.

Internally the L298N consists of four independent power amps with 5-volt digital inputs and four high current, high
voltage power amplifiers capable of driving single DC motors, and both unipolar and bi-polar stepper motors. The
four amplifiers are usually used in pairs forming an H-bridge to switch polarity for to control the direction of a single
DC motor or as two pairs of H-bridges a bi-polar stepper motor.
The four power amplifiers and grouped in pairs of two with individual enable pins (ENA, ENB) and individual
current sense pins (SENSA, SENSB) for each pair. The current sense pins in general can be tied to ground, but
can be inserted a low value resistor, whose voltage reading is proportional to current. ENA, ENB, and In1-In4
are all standard 5-volt TTL logic making connection to most micro-controllers easy. ENA will turn on A1 and A2
when with a digital HIGH (5-volts) and off when LOW (0 volts); the corresponding outputs will be floating when
off. Same is true of ENB, In3 and In4. ENA and ENB can be connected directly together to enable both channels
at once or simply tied to +5 volts and both channels making all four outputs active at all times. A 5-volt TTL level
input to In1, In2 In3, or In4 will produce a corresponding output of Vm (motor voltage) minus about a volt.
The output is used to drive a single motor. An additional motor can also be added to the same module.

IR Sensor
An infrared sensor is an
electronic instrument which is
used to sense certain
characteristics of its surroundings
by either emitting and/or
detecting infrared radiation.
Infrared sensors are also
capable of measuring the heat
being emitted by an object and
detecting motion
The output is fed to the
D7 bit of PIC MC.

ANALOG FEATURES

R305 FINGERPRINT MODULEOperation
Principle: Fingerprint processing includes two parts: fingerprint
enrollment and fingerprint matching (the matching can
be 1:1 or 1:N).
When enrolling, user needs to enter the finger two times.
The system will process the two time finger images,
generate a template of the finger based on processing
results and store the template. When matching, user
enters the finger through optical sensor and system will
generate a template of the finger and compare it with
templates of the finger library. For 1:1 matching, system
will compare the live finger with specific template
designated in the Module; for 1:N matching, or searching,
system will search the whole finger library for the
matching finger. In both circumstances, system will return
the matching result, success or failure

FEATURES

TYPES OF RFID
Many types of RFID exist, but at the highest level, we can divide RFID devices into two classes: active and passive.
Active tags require a power source they’re either connected to a powered infrastructure or use energy stored in an
integrated battery.
In the latter case, a tag’s lifetime is limited by the stored energy, balanced against the number of read operations the
device must undergo.
One example of an active tag is the transponder attached to an aircraft that identifies its national origin.However,
batteries make the cost, size, and life-time of active tags impractical for the retail trade.
Passive RFID is of interest because the tags don’t require batteries or maintenance. The tags also have an indefinite
operational life and are small enough to fit into a practical adhesive label.
A passive tag consists of three parts: an antenna, a semiconductor chip attached to the antenna, and some form of
encapsulation. The tag reader is responsible for powering and communicating with a tag. The tag antenna captures
energy and transfers the tag’s ID (the tag’s chip coordinates this process).
The encapsulation maintains the tag’s integrity and protects the antenna and chip from environmental conditions or
reagents. The encapsulation could be a small glass vial or a laminar plastic substrate with adhesive on one side to
enable easy attachment to goods.

Increasing the number of SECURITY levels e.g. Face Recognition.
Redesigning to include a conveyor belt.
Load bearing capacity and the design of the carousel can be further modified pertaining to its usage.

• Practical approach to be adopted for all the theory learned till
date.
• The interdependence of various branches of engineering on
each other.
• Decision about buying various components based on a lot of
Research work and gathering details about it prior to it.
• Proper planning of deadlines and executing the same in a
group together.
• Having a backup plan when things fail
LEARNINGS THAT WE TAKE WITH US:

With the advent of modern techniques in
every domain of life, the needs and
demands to life a luxurious, hassle-free and
safe life increases. People are always in a
need to store their valuables in a safer and
anytime accessible place.
The primary objective of the project carried
out was to enhance the security level of the
vault system and can be accessible 24x7.
This was achieved by involving three levels
of security system namely the fingerprint
module, the plastic card and 4 digit
password. The system was totally
automated by using a mechanically driven
and programmed using a microcontroller
and IR sensor to stop the desired vault at
the fixed vault position. This in a way
requires no human intervention hence
making the system accessible to the users
beyond the regular bank hours.
The entire project didn’t work in the pre-
planned way and required quite a lot of
changes ranging from the design to the
selection of various components.
But with vigorous efforts and dedicated work
of all the members of the team the desired
objective and an exact prototype was
successfully achieved.
