What is tag 9F33?
EMV Tag 9F33 – Indicates the card data input, CVM, and security capabilities of the terminal for the AID. Byte 1 – Card Data Input Capability. Indicates all the methods supported by the terminal for entering the information from the card into the terminal.
What is TSI in EMV?
The best way to understand EMV is to think of a transaction as a conversation between the card and the terminal. The terminal has two checklists. One is called the “Terminal Verification Results” or TVR. And the other one is called the “Transaction Status Information” or TSI.
What is CVR in EMV?
The fitness evaluation of the command GENERATE AC is a combination of the type of cryptogram returned by the application indicated by the data element Cryptogram Information Data (CID) and the checks performed by the application gathered in the data element Card Verification Results (CVR).
What are terminal capabilities?
In computing and telecommunications, the capabilities of a terminal are various terminal features, above and beyond what is available from a pure teletypewriter, that host systems (and the programs that run on them) can make use of.
What is TVR in EMV?
Terminal verification results (TVR) or Tag ’95’ 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.
What is CVM in EMV?
In the context of an EMV chip transaction, the Cardholder Verification Method, or CVM, is used to evaluate whether the person presenting a payment instrument, such as a payment card, is the legitimate cardholder. An understanding of CVMs is critical to all stakeholders in the payments ecosystem.
What is terminal action?
The terminal has to decides either to proceed the transaction offline, to go online or to reject the transaction. The Terminal will send the decision with a Generate AC command to the card. The decision is based on the Transaction Verification Results.
What are terminal action codes?
Terminal action codes are used in the Terminal Action analysis step in the EMV transaction process. If present, bits of Terminal Action Code (TAC) are compared with the corresponding bits of Issuer Action code (IAC) in a bitwise OR processing.
What is EMV validation?
UL EMV Personalization Validation Tool (UL EMV PVT) is the most thorough and comprehensive test tool for Issuers, Card Personalization Bureaus and Card Manufacturers that want to validate the personalization of their payment cards and mobile payment applications.
What are the CVM capabilities and terminal capabilities?
The CVM capability (Byte 2) is instantiated with values depending on the transaction amount. The Terminal Capabilities is coded according to Annex A.2 of [EMV Book 4]. Indicates the card data input, CVM, and security capabilities of the Terminal. Count of the number of transactions initiated since personalisation.
What should be set to 0B for EMV mode transactions?
For EMV mode transactions, all of the TVR bits sent online to the acquirer shall be set to 0b. Status of the different functions as seen from the terminal. Status of the different functions as seen from the terminal. Local date that the transaction was performed. Local date that the transaction was authorised.
What does 9f35 mean on a credit card?
A proprietary data element with bits 8, 7, and 4 only used to indicate a terminal’s capability to support Kernel 4 mag-stripe or EMV contactless. This data element is OR’d with Terminal Type, Tag ‘9F35’, resulting in a modified Tag ‘9F35’, which is passed to the card when requested.
What is the status of the different functions from the terminal perspective?
Status of the different functions from the Terminal perspective. The Terminal Verification Results is coded according to Annex C.5 of [EMV Book 3]. Status of the different functions as seen from the reader/terminal. For EMV mode transactions, all of the TVR bits sent online to the acquirer shall be set to 0b.
