  1. Personal identification number

    A personal identification number (PIN), or sometimes redundantly a PIN number or PIN code, is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system. The PIN has been the key to facilitating the private data exchange between different data-processing centers in computer networks for financial institutions, governments, and enterprises. PINs may be used to authenticate banking systems with cardholders, governments with citizens, enterprises with employees, and computers with users, among other uses. In common usage, PINs are used in ATM or POS transactions, secure access control (e.g. computer access, door access, car access), internet transactions, or to log into a restricted website.


  1. personal identification number

    A personal identification number (PIN) is a numeric or alphanumeric password or code used in the process of authenticating or identifying an individual to a system and system to an individual. PINs are typically used in conjunction with usernames or other identifiers for access control. In most common usage, it refers to a secret code that a person must provide to access a service or facility, most commonly in electronic transactions such as withdrawing money from an ATM or making a purchase online.


  1. Personal identification number

    A personal identification number is a secret numeric password 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 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. The user is granted access only when the number entered matches with the number stored in the system. Hence, despite the name, a PIN does not personally identify the user. PINs are most often used for automated teller machines but are increasingly used at the point of sale, for debit cards and credit cards. Throughout Europe and Canada the traditional in-store credit card signing process is increasingly being replaced with a system in which the customer is asked to enter their PIN 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 parts of the world, PINs have been used before the introduction of EMV.
