I'm working with a mobile payment terminal and a testing tool for testing EMV transactions. Part of the setup of the terminal involves loading a number of CAP keys into the terminal for use with different types of cards.

I'm curious, how does the terminal go about selecting an appropriate CAP key? The specific problem I'm running into is I have a demo project that is processing AMEX cards with success, but I'm not able to process them in my own project. I'm getting errors such as, "No key was found to do the verification 65 ".

I thought it would be enough to match the Application Identifier, but I'm not seeing any AMEX identifiers in the demo project, even though it's working A0 00 00 00 For the key determination the records usually have next values:.

This list is provided only to facilitate identification of the detailed edits that result in VCPS 2. VCPS 2. Version 2 of this specification adds guidance for supporting EMV contactless, i.EMV is a payment method based upon a technical standard for smart payment cards and for payment terminals and automated teller machines which can accept them.

EMV originally stood for " E uropayM astercardand V isa ", the three companies which created the standard. EMV cards are smart cardsalso called chip cards, integrated circuit cards, or IC cards which store their data on integrated circuit chips, in addition to magnetic stripes for backward compatibility. These include cards that must be physically inserted or "dipped" into a reader, as well as contactless cards that can be read over a short distance using near-field communication technology.

Payment cards which comply with the EMV standard are often called Chip and PIN or Chip and Signature cards, depending on the authentication methods employed by the card issuer, such as a personal identification number PIN or digital signature. In Februarycomputer scientists from Cambridge University demonstrated that an implementation of EMV PIN entry is vulnerable to a man-in-the-middle attack but only implementations where the PIN was validated offline were vulnerable. The customer hands their card to the cashier at the point of sale who then passes the card through a magnetic reader or makes an imprint from the raised text of the card.

In the former case, the system verifies account details and prints a slip for the customer to sign. In the case of a mechanical imprint, the transaction details are filled in, a list of stolen numbers is consulted, and the customer signs the imprinted slip.

In both cases the cashier must verify that the customer's signature matches that on the back of the card to authenticate the transaction. Using the signature on the card as a verification method has a number of security flaws, the most obvious being the relative ease with which cards may go missing before their legitimate owners can sign them. Another involves the erasure and replacement of legitimate signature, and yet another involves the forgery of the correct signature on the card.

Geldkarte in Germany also predates EMV. EMV was designed to allow cards and terminals to be backwardly compatible with these standards.

France has since migrated all its card and terminal infrastructure to EMV. EMV originally stood for E uropayM astercardand V isathe three companies that created the standard. The EMV standard was initially written in and There are two major benefits to moving to smart-card-based credit card payment systems: improved security with associated fraud reductionand the possibility for finer control of "offline" credit-card transaction approvals.

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. New issue debit cards in the US [ when? The common debit application ID is somewhat of a misnomer as each "common" debit application actually uses the resident card association application. EMV chip card transactions improve security against fraud compared to magnetic stripe card transactions that rely on the holder's signature and visual inspection of the card to check for features such as hologram.

The processing time is comparable to online transactions, in which communications delay accounts for the majority of the time, while cryptographic operations at the terminal take comparatively little time. The supposed increased protection from fraud has allowed banks and credit card issuers to push through a "liability shift", such that merchants are now liable as of 1 January in the EU region and 1 October in the US for any fraud that results from transactions on systems that are not EMV-capable.

The majority of implementations of EMV cards and terminals confirm the identity of the cardholder by requiring the entry of a personal identification number PIN rather than signing a paper receipt. Whether or not PIN authentication takes place depends upon the capabilities of the terminal and programming of the card.

When credit cards were first introduced, merchants used mechanical rather than magnetic portable card imprinters that required carbon paper to make an imprint.

They did not communicate electronically with the card issuer, and the card never left the customer's sight. The merchant had to verify transactions over a certain currency limit by telephoning the card issuer.

During the s in the United States, many merchants subscribed to a regularly-updated list of stolen or otherwise invalid credit card numbers.Cookies improve how our website works and how it is used, so that we can continue to improve the site.

Each TLV data object consists of:. A tag, which is used to uniquely identify the data object from the list of tags defined in EMV. All tags currently defined in the EMV specification are encoded over either 1 or 2 bytes although cards may also contain proprietary data objects that can theoretically be longer.

A length, which is used to indicate the length of data associated with the tag. A value, which contains the data associated with the tag. If this is not supported or fails to find a match, the terminal must iterate through its AID list asking the card whether it supports each individual AID. If there are multiple applications in the completed candidate list, or the application requires it, then the cardholder will be asked to choose an application; otherwise it may be automatically selected.

The contactless symbol is the EMVCo -defined symbol displayed on contactless readers at the centre of the landing zone to indicate to cardholders where they should tap their card. The contactless indicator is the EMVCo -defined symbol on a contactless card, to indicate that the card supports contactless payments.

An EMV mode transaction is a contactless payment, designed for markets that support the necessary infrastructure and protocols to meet all the EMV transaction data requirements. Once a reader combination has been chosen, the processing continues according to the card scheme rules associated with the Kernel ID.

ExpressPay is the specification for performing contactless transactions for American Express cards. An EMV Kernel is a set of functions that provides all the necessary processing logic and data that is required to perform an EMV contact or contactless transaction.

The Kernel will be called from the terminal's payment application and the Kernel will utilise the IFD to perform the necessary data exchanges with the card. The Kernel Identifier is used to uniquely identify each of the card scheme kernels that may be supported by the reader and card. The Landing Zone is the area on a contactless reader, indicted by the contactless symbol, at the centre of the RF field. The RF Field is the 3-dimensional space projecting from the landing zone on the contactless reader in which contactless cards can be detected and processed.

It is also known as the contactless field or contactless interface. The track 1 data or more accurately, the track 1 equivalent data is data that is formatted similarly to the data that would typically be found on the track 1 of a magnetic stripe card, and may be generated by a contactless reader or provided by a contactless card for an MSD-Mode transaction.

The TTQ is a collection of indicators that the terminal will set to show the reader capabilities, requirements, and preferences to the card.

The TTQ is only supported by certain card schemes and is only used for contactless transactions. Add EMV Level 1 functionality to embedded systems. Simple and rapid way of adding EMV Level 2 functionality to payment applications within the Windows environment.
