Implementation of EMV Payment Terminal Solution

Introduction

Many companies at the modern merchant services market are looking for an optimal card-present solution to implement. Some of these companies are expanding or re-organizing their activities (a step, which often leads to the need to choose and implement a payment terminal solution). Others are newcomers, which want to accept both card-present and card-not-present payments.

Problem

A company is looking for a universal card-present solution to implement. Either it can be a new solution, which is to replace an old one, or it can be the first card-present solution to be implemented by the company.

Context

The problem is relevant for several categories of businesses:

  • existing companies which already have a card-present solution in place, but want to replace it with a better one (possibly, in response to EMV liability shift)
  • existing companies, which previously dealt only with card-not-present transactions
  • startups that require card-present solutions
  • Strategy

    In order to implement a card present solution in the most reasonable and adequate way, your company needs to take the following important aspects into account.

    What hardware should be used in the new payment terminal solution? Which payment terminals are to be used? What functions should they be capable of performing?

    In order to answer these questions, you should analyze your business situation, the needs of the merchants you are going to service, as well as the price these merchants are willing to pay for the new terminals.

    For example, you might need the cheapest monochrome screen terminals or high-end 7-inch touch-screen ones with the most advanced functionality for your particular case.

    Keep in mind, that payment terminal market is an oligopoly, i.e., it includes only few large vendors, so your choice may be limited. Beside that, most companies’ offers may be quite similar.

    Do you need mobile solutions?

    Some companies offer solutions for both payment terminals and mobile POS systems. Maybe, it might be advantageous for you to deal with such a universal vendor, rather than to involve different vendors for different kinds of solutions.

    Which payment types do you need to handle?

    Do you need EMV contact and EMV contactless payments or are you going to deal only with encrypted swipe payments?

    Do you need standalone or integrated payment terminal solutions?

    Remember, that a payment terminal is just a hardware unit and different kinds of software can be installed on it. While terminal manufacturers (such as Ingenico and VeriFone) offer their own terminal applications, alternative payment terminal solutions are also available from third parties. Such third-party software products may be more suitable for your particular situation, than the software, developed by the terminal vendors themselves (for which you need to pay separately anyway).

    Depending on the type of payment terminal solution that you need (standalone or integrated), you need to evaluate the available software options according to the following three criteria:

    • Quality of user interface. I.e. how the software looks, works, and performs its intended functions inside the terminal (button sizes and colors, supported languages etc.).
    • Ability of the terminal application to communicate with the payment gateway. Some vendors offer terminal applications which are “strategically tied” only to their partner gateways. The question is, thus, whether the terminal application, that you are going to use, is already (or can be) connected to the payment system you need to interact with. You should also avoid situations when in order to deal with different processors you have to use different types of payment terminals and terminal applications, as the process may become too complicated to manage. In other words, your terminal application must be able to smoothly communicate with all back-end payment systems you need.
    • Ease of integration of a payment terminal with the POS system. Many companies still offer legacy integration strategies, which require either installation of DLL libraries or Windows service on the workstation. Both these solutions present deployment challenges, especially, for web-based applications. Beside legacy strategies there are other available options, such as cloud solutions (offered, for instance, by UniPay Gateway).

    As you can see, your choice of a particular terminal solution will not depend so much on the physical hardware and its price, as on the availability of your preferred terminal application on particular terminal models, or on support of a particular payment gateway by the terminal application you want to choose. For example, if your bank or payment gateway tells you that you can only use Ingenico, it makes no difference if you find Verifone more suitable for your business.

    Fulfillment strategies

    One of the most important aspects to consider is payment terminal fulfillment. I.e., who will be loading the new terminals and shipping them to your merchants. There are several options possible.

    You can buy a batch of (say, a 1000) terminals from a vendor or manufacturer, and then use an internal team to inject the respective keys and terminal applications into them as they are shipped to merchants (in smaller quantities). This process requires a whole infrastructure. Although this option is plausible for some companies, most businesses choose to delegate terminal fulfillment to special entities. Consequently, you can partner with a fulfillment center that will install software applications on the terminals, service the terminals, and handle terminal replacement.

    When choosing a fulfillment center, you should consider the following issues:

    • what it costs to buy a new terminal or replace an existing one; what the shipping rates are
    • which software applications (custom software packages) can be loaded
    • which terminal models it supports
    • with which processors it has agreements for PIN key injection (as it needs to be able to inject respective encryption keys), and in which countries
    • if you need some particular terminal application to be installed on your terminals, you should check with the fulfillment center, if it is able to install this application for you.

    When you find a fulfillment center, which is suitable for you in terms of pricing and servicing conditions, and a terminal application, which supports the payment gateway you are (or are going to be) partnering with, your choice of payment terminal solutions may become very limited.

    Example

    You have done a market research and realized that your options include Ingenico iSC 250/480 or VeriFone MX 915/925. However, in order for your terminals to be able to interact with your payment gateway, you need a special terminal application. Only two fulfillment centers are able to install this particular application, and only one of them deals with the three processors, whose keys you need to inject. This fulfillment center supports only Ingenico terminals. In this situation there is no point in some in-depth analysis of specifications and price offerings of VeriFone, as Ingenico turns out to be your only choice.

    EMV certification (if necessary)

    If you need to support EMV standard and keep using your own payment platform, you will need to integrate your terminal solution into an existing payment ecosystem (i.e. integrate your terminals with an existing gateway). This means that you need to go through EMV certification process.

    Remember, that each EMV kernel, installed on devices, which you are using within your solution, must be separately EMV-certified. Consequently, in order to simplify EMV certification process, you need to minimize the number of EMV-kernels on your devices (including EMV-kernels provided by one and the same manufacturer/vendor).

    Example

    A company wants to work with a certain number of models of terminals and mobile devices. Some mobile devices are using the EMV kernel which is used by payment terminals, while other mobile devices are using a different EMV kernel. (For instance, Ingenico uses both its own mobile solutions and solutions, developed by ROAMpay before its acquisition by Ingenico). In this case the company has to certify two EMV kernels, i.e. go through two certifications.

    In order to minimize the number of EMV kernels and, thus, reduce time and cost of EMV certification process, you need to verify, whether all the devices you are going to use, are made by the same manufacturer, and whether one and the same EMV kernel is installed on all the models of these devices.

    Conclusion

    Many newcomers in the merchant services industry erroneously think that selection of a card present solution starts with the analysis of available hardware options. Selection of hardware, in fact, may be the last phase of the process. You should, definitely, know the names of the key hardware brands. However, a decision, based only on hardware specifications, may result in a costly error. The key factors to be considered first and foremost often include terminal application compatibility, support of the necessary gateway integrations, number of necessary EMV certifications (if they are needed), and preferable fulfillment strategies

Getting out of PCI scope

Introduction

More and more companies nowadays accept credit card payments. Payment card industry is regulated by Payment Card Industry Security Standards Council, which has specific security requirements. According to these requirements, each company, dealing with card data, has to go through regular PCI audit, which is quite a costly procedure. That is why many companies are trying to find the answer to the question: how can a business accept payment cards, but remain out of PCI scope.

Problem

The general problem is to move the existing payment system, which is presently in PCI scope, out of it. At the same time, the system has to be able to perform its functions as before.

Context

While some companies cannot avoid PCI audit, because their payment systems are too large, a number of merchants and software companies are technically able to reorganize their infrastructure in such a way, which would allow them to either get out of PCI scope completely, or reduce their “exposure level” and PCI audit costs.

From conceptual viewpoint the problem has several complexity levels.

  • Level 1: Card present vs card not present. If only CNP transactions are involved, it is much easier to reduce exposure level.
  • Level 2: Number of front-end systems.
    If only one front-end system (for instance, a POS system) is involved, the process becomes much more transparent. If there are many front-end systems, a solution must be found for each of them.
  • Level 3: Which kinds of applications are involved?In some cases web applications might be easier to remove out of PCI scope, than desktop applications. If you are dealing with a legacy system which uses obsolete technologies and has limited functionality (or, maybe, the developers who created the system are no longer with the company), the task becomes even more complex.
  • Level 4: Are recurring payments involved? If the answer is “yes”, then there is a need to store cardholder data, and the matter of exposure reduction gets trickier.
  • Level 5: Are all the merchants using different payment systems? Say, if you are a software company, the users of your software can either partner with the same PSPs, or have different independent (individual) processing solutions. So, is payment processing
    unified for all users of your platform, or do they have customized processing solutions associated with local banks or processors?

Strategy

In order to optimize your business infrastructure and successfully get your company out of PCI scope, or at least, reduce your exposure level, you need to perform the following important steps.

  • Consult the PCI auditor. Whatever strategy you have in mind, discuss it with the PCI auditor before implementation. Then compile all the necessary documents to start the process.
  • Decide, which of the components of your payment ecosystem have to be phased out. In the simplest case the system consists of a single software package. However, in many cases, it can include several packages, different terminal solutions, etc, and these components and solutions have to be prioritized.
  • Decide, if (similarly to the previous step) you need to sunset your integrations with some processors and migrate merchants to other processing platforms in order to unify and simplify the process.
  • Decide, whether you need to unify payment processing across your customers. Do you, potentially, need to reduce the number of supported processors and simplify the overall infrastructure, in order to make it more transparent.
  • Decide, whether you need to store cardholder data. If your company uses terminal capture, then you have to send the file with card numbers to your processor on a regular basis. Consequently, you have to store card numbers within your system. However, if you switch to host capture, card numbers no longer have to be stored in the system and sent to the processor.
  • Analyze the following two basic issues in the context of exposure level reduction: card flow and card storage (if necessary). Card flow can be handled in two ways: either using payment pages (mostly for CNP solutions), or (for card present solutions) using P2PE on card readers or payment terminals. For card storage a classical solution is tokenization of card data.
  • Verify, whether CNP, card present, and recurring billing solutions are supported by each of the PSPs your system works with. We should remind that if recurring billing is involved, you or your partner PSPs have to store and, consequently, tokenize card numbers. If some of the PSPs do not support all the necessary services (or if it is more relevant to work with some unified processor-agnostic service and eliminate the necessity to support different tokens), then you should consider partnering with some independent (processor-agnostic) tokenization services. Some information on migration from one processor to another can be found here.
  • Plan the integration works which have to be done for implementation of the new infrastructure. These may include integrations with tokenization services, P2PE service providers, and other entities.
  • Plan cardholder data migration process. If actual card numbers are stored within your system, or if your current tokenization solution is only partial, you need to decide, how and when card numbers will be migrated.

Conclusion

Even if you understand that you are unable to get your system out of PCI scope completely and all you need is to simplify the process of cardholder data handling, you might consider using some standardized open-source payment technology (such as UniPay Gateway), which is capable of performing all the necessary functions, within the existing payment ecosystem. This step will allow you to unify many internal processes and, thus, simplify PCI audit procedure.

Dealing With Multiple International Payment Platforms

Introduction

Present-day globalization tendencies push more and more businesses to process payments in multiple geographical zones.

Particularly, such companies include businesses, which start offering their products online internationally, and franchises, which enter international markets.

The purpose of this article is to outline the problems faced by these companies and try to provide structured step-by-step strategy that they could follow.

Problem

Let us say, there is a company, which wants to solve the problem of multi-currency and international transaction processing for itself or for its clients.

Context

The task of entering an international market can be addressed at one of the three “complexity levels”.

  • Level 1: A company wants to process its own transactions (product sales) in different countries.
  • Level 2: A franchisor wants to operate in different countries, but in each country at most one processing partner is sufficient (a franchisor can impose all franchisees to use a single processor).
  • Level 3: A software vendor company wants to service many clients in different geographic zones using several processing options (support more than one platform or acquiring bank in each country).

Strategy in brief

The crucial issues you will definitely have to deal with (if you want to expand your operations to multiple geographical locations) include:

  • Finding a solution for operations with several currencies
  • Prioritization of regions
  • Prioritization of typical transaction types handled by your payment ecosystem
  • Organization of underwriting and on-boarding processes in new geographies
    • Strategy in detail

      In order to organize the process properly, first of all, you have to study the overall situation and then – answer some fundamental questions.

      • Is it going to be possible to settle transactions in one single currency, or settlement currency must always be the same as authorization currency? If a company wants to charge its customers in a local currency and settle the funds from international sales in a single bank account, it can partner with a single acquirer, that supports dynamic currency conversion. If it plans to settle transactions in the local currency, then a local relationship with a specific bank will be required. In the second case a more complicated payment ecosystem will have to be built.
      • What are the high-priority and low-priority regions? What the actual transaction volume is going to be? Evaluation of transaction volumes is necessary for pricing negotiations and related issues. Establishment of the relationship with a payment processor and implementation of the required technical integration is never a simple process. It takes plenty of time, and it becomes even more difficult at the international scale, especially when several projects are under way. Most likely, you will have to proceed in the sequential manner, which is why it is important to prioritize.
      • What are the transaction types you need to process? Are you going to deal only with online card-not-present transactions? Is card-present transaction support required? Will you need EMV support and respective payment terminals? Usually, it is much easier to find a card-not-present solution, because various local regulations exist for use of the chip cards in a particular region. In some cases region-specific specifications are necessary for you to be able to accept cards in the retail environment. The additional challenge is that in some countries it is not possible to certify your existing EMV solution, and you may be required to use whatever is available on the local market. Some of these available solutions might not fit into your existing payment ecosystem.
      • Which banks will handle the underwriting process, and how merchant accounts are going to be issued? How are you going to integrate with these banks? What is the specific connection mechanism? These questions are extremely relevant for many countries. However, in some countries (say, in North America) there are payment gateways, which work with several processors or acquiring banks, and are able to facilitate your relationship with any one of them. On the international arena, the options might be more limited, because some regions have only few acquiring banks, and some gateways might be limited to work with only specific acquiring partners.

      As we can see, all business details (including corruption as well as local regulations and legislative barriers, which might result in cost increases) must be discussed and considered in advance.

      You must find the gateway, providing the best solution in each specific country in view of the listed questions.

      Finally, you will get a list of countries, banks and payment platforms you will have to partner with. After that you will have to analyze the available gateways and check, which of them have either all or most of the necessary bank connections.

      Example

      Let us consider a case when some “optimal” solution is found. Say, there is a gateway, which supports 3 of the 5 necessary bank connections, but is unable to add the missing 2 and all the subsequent ones (or the payment gateway provider is reluctant, because the cost of new connections is too high). This is just the case when you have to consider creating your own payment ecosystem (for some companies this might be the overall goal).

      Next you have to define, in which countries you will have to start from scratch, and in which countries you have some clients (merchants) already using the system. Keep in mind, that in any case if you are going to expand your operations, a strategy will be needed for on-boarding of new merchants.

      Existing clients

      Example

      A franchising company is a vendor of software for fitness centers. It doesn’t have any integrated solutions within the country. Franchisees have to establish a relationship and purchase standalone terminals from it. Every transaction, made at POS, is processed using the standalone terminal, and then – keyed into the main system of record, provided by the franchisor. The franchisor decides that the solution based on usage of standalone terminals is a bit complicated and it is better to offer integrated payment processing functionality. In this case the franchisor has to migrate the already existing merchant accounts.

      In such a situation, you have to analyze, how to migrate these clients from their existing solutions to the company’s main product. Beside that, you need a strategy for the new underwriting process (get new merchant accounts for the already existing merchants and check if processing costs are going to increase). Finally, you have to define, which technical solutions are needed (in terms of additional integrations) in order to allow merchants to be able to send transactions for processing.

      New clients

      If you have no clients (yet) in some region, you have to work out operations for on-boarding process in each particular country.

      Conclusion

      If you are planning to enter foreign markets, handle new currencies, and process transactions internationally, you need to set up priorities and develop a step-by-step expansion strategy.
