Card payments are getting more and more popular across the world. The dominant standard used for Electronic Funds Transfer transaction is EMV. It is widely used across Europe and Canada, and currently it is being introduced in the USA. The most frequently used Cardholder Veri cation Method in EMV transaction is PIN, which requires from the payment terminal to be equipped with pinpad which incre...

Nowadays, information plays an important role in organizations. Sensitive information is often stored in databases. Traditional mechanisms such as encryption, access control, and authentication cannot provide a high level of confidence. Therefore, the existence of Intrusion Detection Systems in databases is necessary. In this paper, we propose an intrusion detection system for detecting attacks...

In a contactless transaction, when more than one card is presented to the payment terminal’s field, the terminal does not know which card to choose to proceed with the transaction. This situation is called card collision. EMV (which is the primary standard for smart card payments) specifies that the reader should not proceed when it detects a card collision and that instead it should notify the...

We conduct an incentivized experiment to test whether the willingness to pay is higher for debit cards compared to cash for three consumer products. Our findings support this conjecture also after controlling for cash availability, spending type, price familiarity and consumption habits of the products. The evidence thus suggests that different representations of money matters for consumer beha...

Can simple motor actions help people expand their vocabulary? Here we show that word learning depends on where students place their flash cards after studying them. In Experiment 1, participants learned the definitions of ”alien words” with positive or negative emotional valence. After studying each card, they placed it in one of two boxes (top or bottom), according to its valence. Participants...

Credit scoring models, or score cards, can contribute to bank safety and soundness as long as bank management actively participates in the development, implementation, monitoring, and validation of the model. Operational factors, such as accurate implementation of the credit scoring model and adequate training of data input staff, also can have an impact on the effectiveness of models. Changes ...
