Terminal verification results (TVR) or Tag '95' [1] is an EMV data object . The TVR is a series of bits set by the terminal reading an EMV card, based on logical tests (for example has the card expired). This data object is used in the terminal's decision whether to accept, decline or go on-line for a payment transaction.
Offline data authentication is a cryptographic check to validate the card using public-key cryptography. There are three different processes that can be undertaken depending on the card: [citation needed] Static data authentication (SDA) ensures data read from the card has been signed by the card issuer. This prevents modification of data, but ...
In all three modes, the CAP reader asks the EMV card to output a data packet that confirms the cancellation of a fictitious EMV payment transaction, which involves the details entered by the user. This confirmation message contains a message authentication code (typically CBC-MAC / Triple DES ) that is generated with the help of a card-specific ...
EMV contactless symbol used on compatible payment terminals. EMV stands for "Europay, Mastercard, and Visa", the three companies that created the standard.Contactless payment systems are credit cards and debit cards, key fobs, smart cards, or other devices, including smartphones and other mobile devices, that use radio-frequency identification (RFID) or near-field communication (NFC) for ...
ISO 8583 is an international standard for financial transaction card originated interchange messaging. It is the International Organization for Standardization standard for systems that exchange electronic transactions initiated by cardholders using payment cards.
In October 2016, EMVCo published the specification for 3-D Secure 2.0; it is designed to be less intrusive than the first version of the specification, allowing more contextual data to be sent to the customer's card issuer (including mailing addresses and transaction history) to verify and assess the risk of the transaction.

Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
