Defined the PIN Code ?

Answer 1

personal identification number (PIN) is a secret shared between a user and a system that can be used to authenticate the user to the system. Typically, the user is required to provide a non-confidential user identifier or token (such as a banking card) and a confidential PIN to gain access to the system. Upon receiving the User ID and PIN, the system looks up the PIN based upon the User ID and compares the looked-up PIN with the received PIN. If they match, then the user is granted access. If they do not match, then the user is not granted access.

PINs are most often used for ATMs. Throughout Europe the traditional in-store credit card signing process is being replaced with a system where the customer is asked to enter their PIN code instead of signing. In the UK and Ireland this goes under the term 'Chip and PIN', since PINs were introduced at the same time as EMV chips on the cards. In other places in Europe, such as Sweden, PINs have been used already before the introduction of EMV.

PINs are also sometimes used for online systems instead of alphanumeric passwords, which may compromise security. (See password for more details)

PINs are often 4-digit numbers in the range 0000-9999 resulting in 10,000 possible numbers, so that an attacker would need to guess an average of 5000 times to get the correct PIN. Many PIN verification systems allow three attempts, thereby giving a card thief a 1/3000 chance to guess the correct PIN before the PIN is blocked. This holds only if all PINs are equally likely and the attacker has no further information available, which has not been the case with some of the many PIN generation and verification algorithms that banks and ATM manufacturers have used in the past (Kuhn, 1997).

In 2002 two PhD students at Cambridge University, Piotr Zieliński and Mike Bond, discovered a security flaw in the PIN generation system of the IBM 3624, which was duplicated in most later hardware. Known as the decimalization table attack, the flaw would allow someone who has access to a bank's computer system to determine the PIN for an ATM card in an average of 15 guesses. [1] [2]

In 2006, James Goodfellow, the inventor of the personal identification number, was awarded an OBE in the Queen's Birthday Honours List [3].

It is common for people to say PIN number in conversation, e.g please enter your PIN number now ; which would be incorrect as this would translate as personal identification number number. Although it is wrong, most people wouldn't bother to correct it. Also, in some dialects, it is common to pronounce the word "pen" the same as the word "pin." [4] In these cases, the use of "pin number" may be used to avoid confusion. In cases such as: "You need to use your pin number," confusion may be avoided as to whether the person is to enter in a number or use a writing utensil

Answer 2

PIN is short for Postal Index Code. PIN Code is Postal Index Number code, used by the Postal department in India. The Geographical area of the country is divided and indexed with individually distinguishable six digit numbers according to their location, to make identification of the post office serving them, easier. Even where postal articles are marked with insufficient address, giving the correct PIN code would ensure that the article reaches the concerned post office of the area, from where identifying the person or the address becomes simple. Each digit of the six digits in a PIN Code, represents the State, District and the Post Office number.

Answer 4

PIN

Personal Identification Number.

In the context of wireless devices, the PIN is a like a password that prevents other people from using your service. It is numeric code used to unlock the phone and/or complete a call or data transmission. It must be entered each time you use the phone, unless you disable it.

(Note that this is different from the type of "unlocking" that will let you use your phone with a different carrier.)

In GSM phones, the PIN is generally associated with the SIM card, not the phone.

GSM SIM cards will lock up if an incorrect PIN is entered three times in a row. If this happens, a different, longer code called a PUK code is required to unlock the phone.
