Retail Payments

The article analyzes tendencies of national payment systems development in the European Union and Russia: electronic and deposit money, bank cards, financial technologies in the field of retail payments. The author identifies factors that stimulate the development of cashless retail payments and the national payment card systems in the European Union, as well as the problems and prospects of this sector forming in Russia. Recommendations on the development of a competitive environment and financial technologies in the field of retail payments in Russia are proposed.

This chapter considers eight applications of cryptography. These essentially act as case studies relating to all the previous material. For each application, we identify the security requirements, the application constraints, the choice of cryptography used, and the ways that the keys are managed. We begin with the SSL/TLS protocols used to secure Internet communications. We then examine the cryptography used in W-Fi networks, showing that early cryptographic design mistakes have subsequently been corrected. We then examine the evolving cryptography used to secure mobile telecommunications. This is followed by a discussion of the cryptography that underpins the security of payment card transactions. We look at the cryptography of video broadcasting and identity cards. We then examine the cryptography behind the Tor project, which use cryptography to support anonymous communication on the Internet. Finally, we examine the clever cryptographic design of Bitcoin, showing how use of cryptography can facilitate digital currency.

Abstract In Electronic Payment Networks (EPNs), the No-Surcharge Rule (NSR) requires that merchants charge at most the same amount for a payment card transaction as for cash. In this paper, I use a three-party model (consumers, local monopolistic merchants, and a proprietary EPN) with endogenous transaction volumes, heterogeneous card use benefits for merchants and network externalities of card-accepting merchants on cardholders to assess the efficiency and welfare effects of the NSR. I show that the NSR: (i) promotes retail price efficiency for cardholders, and (ii) inefficiently reduces card acceptance among merchants. The NSR can enhance social welfare and improve payment efficiency by shifting output from cash payers to cardholders. However, if network externalities are sufficiently strong, the reduction of card payment acceptance affects cardholders negatively and, with the exception of the EPN, all agents will be worse off under the NSR. This paper also suggests that the NSR may be an instrument to decrease cash usage, but the social optimal policy on the NSR may depend on the competitive conditions in each market.
