Credit-based electronic payment systems are considered to play important roles in future automated payment systems. Like most other types of payment systems, however, credit-based systems proposed so far generally involve computationally expensive cryptographic operations. Such a relatively heavy computational load is preventing credit-based systems from being used in applications which require...

This paper investigates how the supplier’s bargaining power affects trade credit supply. We use a novel firm-level database of Chinese firms with unique information on the amount, terms, and payment history of trade credit extended to customers and detailed information on product market structure and clients-supplier relationships. We document that suppliers with weak bargaining power towards t...

In credit based payment systems, con dential data such as PIN and credit card number embedded in an electronic credit card must be protected. The authenticity of an electronic credit card in a payment process is normally achieved through an on-line trusted server such as a nancial institution that runs the payment system. This paper considers some novel secure electronic credit card based payme...

Traditional credit card payment is not secure against credit card frauds because an attacker can easily know a semisecret credit card number that is repetitively used. Recently one-time transaction number has been proposed by some researchers and credit card companies to enhance the security in credit card payment. Following this idea, we present a practical security enhancement scheme for one-...

In spite of its commercial importance and signs of clear concern in public policy arenas, trade credit has not been subjected to systematic, extended analysis in the business ethics literature, even where suppliers as a stakeholder group have been considered. This paper makes the case for serious consideration of the ethics of trade credit and explores the issues surrounding slow payment of deb...

In this article, we investigate why merchants accept credit cards for payment despite the relatively high cost of processing these types of transactions. A two-period model is constructed to determine under what conditions a credit card equilibrium would exist. The results of the model indicate that when the cost of funds is not too high and when the merchant’s profit margin is sufficiently hig...

This paper, studies the coordination of two-echelon supply chains using a credit (delayed) payment option and/or a wholesale price discount offer. We develop models for optimizing individual members’, as well as supply chain’s objectives. These models lead to the determination of the retail price and the order quantity for the buyer, as well as the production batch size, wholesale discount and/...

In a recent paper, Khanra, Ghosh and Chaudhuri’s (2011) presented an EOQ model for a deteriorating item with time dependent quadratic demand under permissible delay in payment. Deterioration considered in most of the EOQ models is constant, while in most of the practical cases the deterioration rate increases with time. This work is motivated by Khanra, Ghosh and Chaudhuri’s (2011) paper extend...

Consumers’ ability to purchase goods and services from anywhere and at any time is a critical factor in the ubiquity of e-commerce. Credit cards enable a medium of exchange that facilitates the global e-commerce marketplace. Credit card providers’ and bank account service sites provide powerful tools for the individual to manage their credit card accounts, and allowing payment of monthly credit...
