E Commerce

Abstract

The growth of international interconnected computer networks and the pervasive trend in commerce of using these networks as a new field for business operations stimulated demand for new payment methods. These new methods needed to acquire unprecedented levels of security, speed, privacy, decentralization, and internationalization for digital commerce to be accepted by both consumers and businesses. Three such electronic payment methods are examined: 1. the generic, widely used electronic fund transfer, 2. the proposals for a digital cash standard, and 3. the real-world technology called Ecash. These methods are examined in terms of the dynamics of transaction clearance, and the effects on money supply and the macro economy.

INTRODUCTION

THE extraordinary growth of international interconnected computer networks and the pervasive trend in commerce of using these networks as a new field for business operations stimulated demand for new payment methods. These new methods had to acquire unprecedented levels of security, speed, privacy, decentralization, and internationalization for digital commerce to be accepted by both consumers and businesses. This report analyzes three such electronic payment methods:

*The generic, widely used electronic fund transfer

*The proposals for a digital cash standard

*The real-world technology called Ecash

These methods are examined in terms of the dynamics of transaction clearance; the effects on money supply and the macro economy; and their classification in terms of money and cash. This report does not go into detail on the countless encryption systems, protocols, algorithms, and other technical matters concerning the new systems. The need to pay for transactions is the root of all electronic payment systems. Nonetheless, electronic payment systems are simply logical evolutionary steps that began with recognition of the limits of bartering.

Electronic Fund Transfer

The electronic checking system for electronic payments has been in use since the late 1960s. For many consumer end users, electronic checking and electronic payment is the same thing, although the assertion does not apply in all cases. Electronic checking uses the existing banking structure to its fullest potential by eliminating paper checks. Electronic fund transfer and electronic checking are synonymous. Electronic fund transfer is an extremely varied system.

Examples include:

*Paying university fees through the banking automatic teller machine (ATM) network,

*Paying telephone bills through monthly bank account deductions, and

*Large-value (ranging from thousands to millions of dollars) interbank overseas fund transfers.

Conceptually, electronic checking, and almost all electronic payments, involves three agents-the buyer, the seller, and the intermediary. The buyer initiates a transaction with the seller, and the seller demands payment. The buyer then obtains a unique guarantee of payment (the virtual equivalent of a check) from the intermediary. This guarantee (in electronic form) debits the buyer's account with the intermediary. The buyer then gives the guarantee to the seller and the seller gives the guarantee to the intermediary. The guarantee credits the seller's account with the intermediary. Schematically, the transaction is like a conventional checking transaction. Nevertheless, when conducted electronically, the certification is an electronic flow documented by the intermediary.

Since electronic checking is essentially checking, it can be analyzed as if it were conventional checking. Payments made via electronic checking would be conducted without cash and paper. Instead of sending a check or paying at a counter, the buyer would initiate an electronic checking certification via computer or point-of-sale terminal. If such a transaction is done as a substitute for paying cash, electronic checking could substantially reduce the transaction's demand for money.

The technology of e-cash has ceased to be the main topic of discussion in the digital money world. The debate has moved on to the implications of the widespread use of e-cash in both business-to-consumer and business-to-business transactions. There are already more than 90 million e-purses in circulation in the EU and common standards are emerging: in addition, companies such as IBM and Digital are piloting a variety of Internet-based payment mechanisms.
