11. ATM Device’s An ATM is simply a data terminal
with two input and four output
devices.
communicate through, a host processor. The host processor is analogous to an Internet service provider (ISP) in that it is the gateway through which all the various ATM networks become available to the cardholder (the person wanting the cash).

12. ATM has two input devices:
Card reader - The card reader captures the account information stored on the magnetic stripe on the back of an ATMcard.
Keypad - The keypad lets the cardholder tell the bank what kind of transaction is required (cash withdrawal, balance inquiry, etc.)

13. An ATM has four output devices
Speaker - The speaker provides the cardholder
with Auditory feedback when a key is pressed.
Display screen - The display screen Prompts the cardholder through each Step of the transaction process.
Display screen - The display screen Prompts the cardholder through each Step of the transaction process.
Receipt printer - The receipt printer provides the
Cardholder with a paper receipt of the transaction
Cash dispenser - The heart of an ATM is the safe and
cash-dispensing mechanism. The entire bottom portion
of most small ATMs is a safe that contains the cash

14. Most host processors can support either
Most host processors can support either leased-line or dial-up machines.
Leased-line machines connect directly to the Host processor through a four-wire, point-to point, dedicated telephone line.
Dial-up ATMs connect to the host processor through a normal phone line using a modem and a toll-free number, or through an Internet service provider using a local

15. ATM, Automated Teller Machine
Money moves electronically from user’s account to host account to merchant’s account.
New innovations: machines that verbally prompt
When a cardholder wants to do an ATM transaction, he or she provides the necessary information by means of the card reader and keypad. The ATM forwards this information to the host processor, which routes the transaction request to the cardholder's bank or institution that issued the card. If the cardholder is requesting cash, the host processor causes an electronic funds transfer to take place from the customer's checking account to the host processor's account. Once the funds are transferred to the host processor's bank account, the processor sends an approval code to the ATM authorizing the machine to dispense the cash. The processor then ACHs (automatic clearing house) the cardholder's funds into the merchant's bank account, usually the next bank business day. In this way, the merchant is reimbursed for all funds dispensed by the ATM. So when cash is requested, the money moves electronically from the user’s account to the host's account to the merchant's account.
New innovations for ATMs will include machines that will verbally prompt a customer for their card, their PIN and what type of transaction they would like.

16. How Do ATMs Work?
Simple data terminal communicating through a host processor
Can be connected through:
a dedicated telephone line
dail-up modem
Internet service provider
An ATM is simply a data terminal. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is similar to an Internet service provider (ISP) in that it is the gateway through which all the various ATM networks become available to the cardholder (the person wanting the cash).
Most host processors can support either leased-line or dial-up machines. Leased-line machines connect directly to the host processor through a four-wire, point-to-point, dedicated telephone line. Dial-up ATMs connect to the host processor through a normal phone line using a modem and a toll-free number, or through an Internet service provider using a local access number via a modem.
Communications between the ATM and the bank's central computer are encrypted to prevent would-be thieves from tapping into the phone lines, recording the signals sent to the ATM to authorize the dispensing of cash and then feeding the same signals to the ATM to trick it into unauthorized dispensing of cash.

17. ATMS
Most people use ATMs to get cash. Other popular uses for ATMS are to check account balances of your accounts and to transfer money between savings and checking accounts. Remember to record all ATM transactions and fees in your check register to avoid overdrawing your account.

18. ATM Machine
Not all ATM machines will look exactly like this one. Banks provide instructions on their ATM machines. If you need help using the ATM at your bank, ask for assistance when you open the account.
The ATM machine screen will prompt you to enter information to make your transaction.

19. ATM Security
ATMs keep your personal identification number (PIN) and other information safe by using encryption
Don't write down your PIN. If you must write it
down, do not store it in your wallet or purse.
Make your PIN a series of letters or numbers that
you can easily remember, but that cannot easily be associated with you personally.
Avoid using birth dates, initials, house numbers or your phone number.

20. ATM Machine
If you make any mistakes when entering the information prompted by the ATM machine, you can press ‘Cancel” and start over. If there is any problem with the machine, call your bank.

21. ATM Deposits
You can also deposit checks through your bank’s ATM. Always get your receipt so you have proof of the deposit made.
ATM machines have special envelopes to make deposits. The envelopes are found in a slot by the ATM machine.
Deposit slips are not always required when making ATM deposits, but you need to fill in the information listed on the envelopes.
