Chip and PIN
Chip and PIN combines EMV chip processing with a personal identification number to authenticate a card-present payment and its cardholder.
Card-authentication concepts covering EMV chips, PINs, contactless communication, magnetic stripes, and payment credential evidence.
Card authentication and chip technology determine how a card or compatible device exchanges credentials with a terminal. The method affects counterfeit-fraud controls and transaction evidence, but it does not by itself establish cardholder intent, issuer approval, final settlement, or liability.
EMV Technology provides the framework for many contact and contactless chip payments. Smart Card is the broader integrated-circuit concept, while Multifunctional Card describes a credential supporting more than one operational application.
Chip and PIN combines chip processing with one cardholder-verification method. NFC describes short-range communication used by many contactless devices, and Magnetic Stripe Card explains the static-data technology that may still appear in fallback transactions.
Start with the recorded entry mode: contact chip, contactless, magnetic stripe, fallback, manual entry, or wallet credential. Then separate card authentication from Personal Identification Number or other cardholder verification, issuer authorization, merchant capture, clearing, settlement, and any later dispute.
Terminal records, issuer responses, application identifiers, verification results, reversals, and settlement entries provide different evidence. Current network, issuer, merchant, and jurisdictional rules determine how that evidence affects a specific fraud or liability decision.

Chip and PIN combines EMV chip processing with a personal identification number to authenticate a card-present payment and its cardholder.
EMV technology is the chip-payment framework that authenticates payment devices and transaction data for contact and contactless card-present payments.
A magnetic stripe card stores static encoded data on a magnetic band that a compatible terminal reads when the card is swiped.
A multifunctional card supports more than one payment, account-access, identity, loyalty, transit, stored-value, or access-control function.
NFC is a short-range communication technology used by compatible cards, phones, wearables, tags, and terminals for contactless data exchange.
A personal identification number is a secret numeric credential used to verify a customer or cardholder for ATM, debit-card, banking, and other transactions.
A smart card contains an integrated circuit that can store, process, and communicate payment, identity, access, or stored-value information.
