Heartland Payment Systems: lessons learned from a data breach

On August 13, 2009, the Payment Cards Center hosted a workshop examining the changing nature of data security in consumer electronic payments. The center invited the chairman and CEO of Heartland Payment Systems (HPS or Heartland), Robert (Bob) Carr, to lead this discussion and to share his experiences stemming from the data breach at his company in late 2008 and, as important, to discuss lessons learned as a result of this event. The former director of the Payment Cards Center, Peter Burns, who is acting as a senior payments advisor to HPS, also joined the discussion to outline Heartland's post-breach efforts aimed at improving information sharing and data security within the consumer payments industry. In conclusion, Carr introduced several technology solutions that are under discussion in payment security circles as ways to better secure payment card data as they move among the different parties in the card payment systems: end-to-end encryption, tokenization, and chip technology. While HPS has been very supportive of end-to-end encryption, each of these alternatives offers its own set of advantages and disadvantages.Payment systems ; Data protection ; Electronic commerce

A multi-agent architecture for electronic payment

The Internet has brought about innumerable changes to the way enterprises do business. An essential problem to be solved before the widespread commercial use of the Internet is to provide a trustworthy solution for electronic payment. We propose a multi-agent mediated electronic payment architecture in this paper. It is aimed at providing an agent-based approach to accommodate multiple e-payment schemes. Through a layered design of the payment structure and a well-defined uniform payment interface, the architecture shows good scalability. When a new e-payment scheme or implementation is available, it can be plugged into the framework easily. In addition, we construct a framework allowing multiple agents to work cooperatively to realize automation of electronic payment. A prototype has been built to illustrate the functionality of this design. Finally we discuss the security issues

Payment Systems in Malaysia: Recent Developments and Issues

Payment systems in Malaysia have been undergoing changes in recent years. Among the notable changes is the emergence of electronic-based payment systems. The central bank has been playing an active role in shaping the development of payment systems, particularly in the gradual introduction of electronic-based payment schemes, in the belief that these have the potential to increase efficiency in the economy as whole. The active introduction of e-payment instruments has increased both the value and volume of transactions per capita use of e-payment instruments in recent years. Checks continue to be the major payment instrument, however. Small- and medium-sized enterprises could benefit tremendously from the use of e-payment schemes through more efficient business operations, cost reductions, enhanced security and wider payment channel choice. Noted improvements have also resulted from the introduction of large-value payment systems, such as the payment versus payment infrastructure for the settlement of Malaysian ringgit (RM)-United States (US) dollar (US$) foreign exchange trades and the delivery versus payment settlement for US dollar securities that are issued, deposited and traded in Malaysia. The development of the domestic payment system is becoming more important in the development of a deep and active domestic financial market that promotes financial market stability and the reinvestment of savings in the country. Closer financial market integration in the region and closer cooperation and policy coordination among the monetary authorities in the region is becoming increasingly important. Eight years after implementation in Malaysia, the e-payment schemes should be studied to assess any economic benefits they may have provided.malaysian payment systems; information and communication technology; asian payment systems study

Optimal Dividend Payments for the Piecewise-Deterministic Poisson Risk Model

This paper considers the optimal dividend payment problem in piecewise-deterministic compound Poisson risk models. The objective is to maximize the expected discounted dividend payout up to the time of ruin. We provide a comparative study in this general framework of both restricted and unrestricted payment schemes, which were only previously treated separately in certain special cases of risk models in the literature. In the case of restricted payment scheme, the value function is shown to be a classical solution of the corresponding HJB equation, which in turn leads to an optimal restricted payment policy known as the threshold strategy. In the case of unrestricted payment scheme, by solving the associated integro-differential quasi-variational inequality, we obtain the value function as well as an optimal unrestricted dividend payment scheme known as the barrier strategy. When claim sizes are exponentially distributed, we provide easily verifiable conditions under which the threshold and barrier strategies are optimal restricted and unrestricted dividend payment policies, respectively. The main results are illustrated with several examples, including a new example concerning regressive growth rates.Comment: Key Words: Piecewise-deterministic compound Poisson model, optimal stochastic control, HJB equation, quasi-variational inequality, threshold strategy, barrier strateg

Evidence-Informed Case Rates: A New Health Care Payment Model

Suggests a new payment model whereby providers are paid a single, risk-adjusted payment across inpatient and outpatient settings to care for a patient diagnosed with a specific condition

Fractal behind smart shopping

The 'minimal' payment - a payment method which minimizes the number of coins in a purse - is presented. We focus on a time series of change given back to a shopper repeating the minimal payment. The delay plot shows visually that the set of successive change possesses a fine structure similar to the Sierpinski gasket. We also estimate effectivity of the minimal-payment method by means of the average number of coins in a purse, and conclude that the minimal-payment strategy is the best to reduce the number of coins in a purse. Moreover, we compare our results to the rule-60 cellular automaton and the Pascal-Sierpinski gaskets, which are known as generators of the discrete Sierpinski gasket.Comment: 16 page

Retail Payment Systems: What can we Learn from Two-Sided Markets?

Some retail payment systems can be modelled as two-sided markets, where a payment system facilitates money exchanges between consumers on one side and merchants on the other. The system sets rules and standards, to ensure usage and acceptance of its payment instruments by consumers and merchants respectively. Some retail payment systems exhibit indirect network externalities, which is one of the main criteria used to define two-sided markets. As more consumers use the payment platform, more merchants are encouraged to join it. Conversely, the value of holding payment instruments increases with the number of merchants accepting them. The theory of two-sided markets contributes to a better understanding of these retail payment systems, by showing that an asymmetric allocation of costs is needed to maximise the volume of transactions. It also starts to offer results that could explain competition between payment platforms. However, this theory entails some limits to a thorough understanding of retail payment systems. Firstly, we show that some retail payment systems, such as credit transfer or direct debit systems, do not necessarily fulfil all the theoretical criteria used to define twosided markets. Moreover, this theory does not take into account specific features of the payment industry, such as risk management or fraud prevention. This leads us to propose new research directions.payment systems; two-sided markets; platform competition; payment cards
