* Encrypted PIN Pad, a component of an automated teller machine

Some thieves have surreptitiously added equipment to publicly accessible automatic teller machines ; a fraudulent card stripe reader would capture the contents of the magnetic stripe while a hidden camera would sneak a peek at the user's PIN.

Since automatic teller machines also check for the PIN, this measure strongly reduces the incentive to steal Cartes Bleues, since the cards are essentially useless without the PIN ( though one may try using the card number for mail-order or e-retailing ).

Using this method, the customer does not need to authenticate his or her identity by PIN entry or signature, as on a regular machine.

This is also the case for a cash machine, except that the ' user name ' is typically the account number stored on the bank customer's card, and the PIN is usually quite short ( 4 to 6 digits ).

*" I forgot my PIN number for the ATM machine.

James Goodfellow developed an alternative ATM design, using PIN technology ( which he invented ), resembling modern ATMs more than Shepherd-Barron's machine.

A subset of tautology is RAS syndrome in which one of the words represented by an acronym is then repeated outside the acronym: " ATM machine ", " HIV virus ", " PIN number " and " RAID array ".

However, financial institutions are in the process of rolling out smart cards with integrated circuits (" chips ") that will enable verification by entering a personal identification number ( PIN ) at the EFTPOS terminal.

Customers inserted the card into the merchant's POS terminal, then typed the PIN, before the transaction was accepted.

In February 2010 computer scientists from Cambridge University demonstrated that an implementation of EMV PIN entry is vulnerable to a man-in-the-middle attack ; however, the way PINs are processed depends on the capabilities of the card and the terminal, showing that attacks against card security are possible depending on the implementation.

The use of a PIN and cryptographic algorithms such as DES, Triple-DES, RSA and SHA provide authentication of the card to the processing terminal and the card issuer's host system.

Whether or not PIN authentication takes place depends upon the capabilities of the terminal and programming of the card.

Once the card has been verified as authentic, the customer enters a 4-digit PIN, which is submitted to the chip on the smartcard ; if the two match, the chip tells the terminal the PIN was correct, otherwise it informs it the PIN was incorrect.

Since the introduction of Chip and PIN, cloning of the chip is not feasible ; only the magnetic stripe can be copied, and a copied card cannot be used on a PIN terminal.

When paying for groceries, the SNAP customer's card is run through an electronic reader or a point of sale terminal ( POS ), and the recipient enters the secret PIN to access the food stamp account.

The cardholder presents the card at the point of sale ( POS ) and this is swiped through the terminal by the assistant or the customer or inserted into a chip and PIN device.

This attack's major weakness is that it requires the user of the devices under attack to re-enter the PIN during the attack when the device prompts them to.

This reduces the security of the scheme to that of the PIN system, although it still requires an attacker to possess the card.

Entering a PIN code to activate the smart card commonly requires a numeric keypad.

Additionally, once any form of parental controls are enabled, the " Other Channels " menu requires PIN entry on every use.

* Security module is activated and requires the input of the PIN

This process requires modification of the auxin transporters ( PIN proteins ).

The term passcode is sometimes used when the secret information is purely numeric, such as the personal identification number ( PIN ) commonly used for ATM access.

* Something you know, such as a password or a personal identification number ( PIN ).

Authentication is provided by the customer entering a personal identification number ( PIN ).

* the knowledge factors: Something the user knows ( e. g., a password, pass phrase, or personal identification number ( PIN ), challenge response ( the user must answer a question ))

The protection of the private key is the idea behind the United States Department of Defense's Common Access Card ( CAC ), which never allows the key to leave the card and therefore necessitates the possession of the card in addition to the personal identification number ( PIN ) code necessary to unlock the card for permission to use it for encryption and digital signatures.

Typically, a user must activate his smart card by entering a personal identification number or PIN code ( thus providing two-factor authentication ).

A SIM card contains its unique serial number ( ICCID ), international mobile subscriber identity ( IMSI ), security authentication and ciphering information, temporary information related to the local network, a list of the services the user has access to and two passwords: a personal identification number ( PIN ) for ordinary use and a personal unblocking code ( PUK ) for PIN unlocking.

The word " chip " refers to a computer chip embedded in the smartcard ; the word PIN refers to a personal identification number that must be supplied by the customer.

To solve this, banks and retailers are replacing traditional magnetic stripe equipment with smartcard technology, where credit and debit cards contain an embedded microchip and are authenticated automatically using a personal identification number ( PIN ).

Courts in various jurisdictions have decided that enforceable electronic signatures can include agreements made by email, entering a personal identification number ( PIN ) into a bank ATM, signing a credit or debit slip with a digital pen pad device ( an application of graphics tablet technology ) at a point of sale, installing software with a clickwrap software license agreement on the package, and signing electronic documents online.

* PIN number ( personal identification number number )

Customers enter their personal identification number ( PIN ) and the amount paid is deducted from either their chequing or savings accounts.

A plastic debit card, similar to a bank card, is issued and a personal identification number ( PIN ) is assigned or chosen by the recipient to give access to the account.

A Personal Unlock Code ( PUC ), also known as a PIN Unlocked Key ( PUK ), is used in 3GPP mobile phones to reset a personal identification number ( PIN ) that has been lost or forgotten.

By constructing a fake web site that looks like a legitimate site that might ask for the user's personal information, such as a copy of a bank's website, the fraudster can " phish ", or steal by means of false pretenses, a victim's passwords, PIN or bank account number.

The information available in the registry include patient ’ s personal information ( PIN, sex, age and place of residence ), medical records ( date of diagnosis, site of the tumor, method used for diagnosis, and hospital where the patient is being treated ), and follow-up data ( date and cause of death or date of migration ).

These pieces of information can range from generic things such as a user account or email to something as personal as a bank account number and PIN ( personal identification numbers ).

The Shepherd-Barron dispenser actually predated the introduction of the plastic card with its magnetic strip: the machines used special cheques which had been impregnated with a radioactive compound of carbon-14, which was detected and matched against the personal identification number ( PIN ) entered on a keypad.

Soliciting personal information in response to challenge questions simply solicits more of " something the user knows ", similar to a login, a password, or a PIN.
