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.
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 ...
One of the original goals of EMV was to provide for multiple applications on a card: for a credit and debit card application or an e-purse. Beginning in 2013, new-issue debit cards in the US contain two applications — a card association (Visa, Mastercard etc.) application, and a common debit application.

A chargeback is a return of money to a payer of a transaction, especially a credit card transaction. Most commonly the payer is a consumer. The chargeback reverses a money transfer from the consumer's bank account, line of credit, or credit card. The chargeback is ordered by the bank that issued the consumer's payment card. In the distribution ...
The two applications may share certain data, such as PIN, while other data is not shared in instances where it is only applicable to one application (i.e., terminal risk management data for EMV) or advantages to have separate (i.e., transaction counter, so that EMV and CAP transactions increment separate counters which can be verified more ...
Regardless of the outcome of the chargeback, merchants generally pay a chargeback fee which typically ranges anywhere from $20 to $100. [9] A 2016 study by LexisNexis stated that chargeback fraud costs merchants $2.40 for every $1 lost. This is because of product-loss, banking fines, penalties and administrative costs. [10]
The security level of such a transaction is better than a mag-stripe card, as the chip cryptographically generates a code which can be verified by the card issuer's systems. Contactless EMV cards have two interfaces (contact and contactless) and work as a normal EMV card via their contact interface.
