This document discusses embedded systems and ATM machines. It defines an embedded system as a combination of hardware and software designed for a specific task. An ATM machine is then described as an embedded system that allows customers to perform basic banking functions even when the bank is closed. The major components of an ATM machine are identified as the card reader, host processor, keypad/touchpad, speaker, LCD/CRT screen, receipt printer, and cash dispenser. Their individual functions are explained. Advantages and disadvantages of ATM machines are also briefly mentioned.

2. What is an embedded system
 An embedded system is combination of some
hardware & software either fixed in capability or
programming e.g. industrial machine, auto mobile,
medical equipment, household appliances, airplanes,
toys ,PDA
 It is dedicated to specific task design.
 Engineers can optimize if reducing size and cost of
the product at the same time increasing the
reliability and performance.

8. MAJOR COMPONENTS OF ATM
ATM machine do have various major components
which are responsible for the functioning of the
Automated teller machine.

9. CARD READER:
 If there will be no card reader, then ATM card can
not be read so no transaction can be done by
machine.
 ATM card is required to swipe through this card
reader slot.
 After swiping card it captures the account
information through magnetic stripe of ATM.
 After retrieving the correct information of your
account, card reader send this information to the
host processor for further process.

10. HOST PROCESSOR:
 Host processor is the heart of ATM machine.
 It contacts the bank server and retrieves your
account details such as available balance, previous
transactions, PIN etc
 It verifies your PIN number and if it matches with
the provided PIN number from the bank server, you
are allowed to make the transaction.
 To take your PIN and other requests form user, there
will be a keypad or touch pad.

11. KEYPAD OR TOUCH PAD:
 Key pad or touch pad is responsible for
taking input from the user.
 On this pad, numbers and few other
keys such as Clear, OK etc., will be
placed.
 Key pad transfers your inputted data to
host controller to process the request.

12. SPEAKER:
 Speaker is placed in ATM machine which is
responsible for audio alerts.
 When you press any key, this speaker
confirm the pressing of key by producing a
beep sound alert.
 It assures you that the key pad is working.
 So speaker is also very important part of
ATM machine.

13. LCD or CRT screen:
 Another major integral part of the ATM machine is
its Cathode Ray Tube (CRT) or Liquid Crystal Diode
(LCD) screen.
 CRT or LCD screen is responsible for visual display
of your transactions.
 It is responsible for displaying your name, entered
amount, account number etc.
 Without CRT or LCD display screen, the transactions
from ATM machine would have become more
difficult.

14. Receipt printer:
 Receipt printer is responsible for the printing of your
transaction's receipt.
 It will print whether the transaction is successful or
not.
 It contains the important information in the form of
fixed codes by which we can assess the transaction
status and its reason of failure.
 SO receipt printer is a vital part of automated teller
machine.

15. Cash dispenser:
 The most important part of automated teller
machine is its cash dispenser.
 The cash dispenser is responsible for giving
out the correct amount of cash you have
requested for.
 So after getting instruction from host
controller to pay the money, cash dispenser
will count the money and dispenses the
money out of it.

16.  Making withdrawals.
 Checking balances and updating Account
information.
 Making deposits.
 Making funds Transfer.
 Making payments.

17. 1)Customer have access to the cash in bank
account whenever he needed.
2)customer can travel anywhere without cash.
3) If customer have ever faced a need of
money, then he can probably access on atm
machine.
4)For eg., if customer are in stores that does
not take checks and credit cards but it has an
atm he can withdraw the money for his.

18.  Not available in remote places.
 cannot avoid illegal use in case of
stolen card.
