Credit and debit cards, rather than actual money, have become the universal payment means. With these cards, it has become possible to buy expensive items easily without an additional complex authentication procedure being conducted. However, card transaction features are targeted by criminals seeking to use a lost or stolen card and looking for a chance to replicate it. Accidents, whether caus...

Credit allows a lender to loan out surplus capital borrower. In the traditional economy, credit bears risk that borrower may default on its debt, hence requires upfront collateral from borrower, plus interest fee payments. Due atomicity of blockchain transactions, lenders can offer flash loans, i.e., loans are only valid within one transaction and must be repaid by end transaction. This concept...

Access to credit markets is generally considered a hallmark of developed economies. In the United States, most households appear to have substantial ability to borrow; indeed, households in the United States have an average of over $23,000 in nonmortgage debt alone. Nevertheless, economists often point to limited borrowing opportunities for lower-income households to explain anomalous findings ...

Inductive learning and classification techniques have been applied in many problems in diverse areas. In this paper we describe an AI-based approach that combines inductive learning algorithms and meta-learning methods as a means to compute accurate classification models for detecting electronic fraud. Inductive learning algorithms are used to compute detectors of anomalous or errant behavior o...

Then consider the case of Sofortüberweisung, a controversial entrant to the payment market in Germany. Its name means “instant payment,” and its service has taken off rapidly in the past 2-3 years. Branded as Sofort (Instant), this service provides merchants with a low-cost payment service for online shopping. It is promoted by some large sites (such as airlines) by exempting users from the sur...

The threat of credit card fraud is arguably the most serious issue of concern to e-commerce participants, including consumers and merchants. SSL/TLS and SET are two widely discussed means of securing online credit card payments. Because of implementation issues, SET has not really been adopted by e-commerce participants, whereas, despite the fact that it does not address all security issues, SS...

The Research is to predict the accuracy of credit card fraudulent transactions using Light Gradient Booster algorithm.Novel with sample size =10 then Logistic Regression = 10 were executed for estimating rate transactions. sigmoid functions used in maps values between 0 and 1. Algorithm has a Maximum (91.6%) while comparing performance (81.4%). There was statistical significance difference p 0....

Any business that operates on the Internet and accepts payments through debit or credit cards, also implicitly accepts that some transaction may be fraudulent. The design of effective strategies to face this problem is challenging, due to factors such as the heterogeneity and the non stationary distribution of the data, as well as the presence of an imbalanced class distribution, and the scarci...

Asatisfactory pace of economic growth in any economy is contingent upon availability of adequate capital. A well-developed securities market, while acting as a provider of funding for economic activity at the macro level, plays specific roles in an economy: it diffuses stress on the banking sector by diversifying credit risk across the economy, supplies funds for long-term investment needs of t...
