Smart Card Hardware

The hardware of the smart card includes contacts located on the surface of the plastic base, an integrated central processor and various types of memory. Some smart cards also have a coprocessor for mathematical calculations. Smart Card Contacts There are eight contacts on the surface of the smart card. Their functional purpose is shown in Figure 2.2. The dimensions and location of the contacts are regulated in section 2 of the ISO 7816 standard. The voltage on this contact can be 3 V or 5 V. The maximum deviation is 10%. The supply voltage...

Types of smart cards for the EMV program

This chapter is a brief introduction to the world of smart cards. We will try to familiarize the reader with the basics of smart card technology to help him understand the main idea of this book. If the reader wants to get a deeper knowledge of smart card technology, we will refer him to two books. The first book is Rankl and Effing [1], and the second is Guthery and Jurgensen [2]. These works contain comprehensive information on this topic. Readers who are familiar with smart card technology may skip this chapter. Smart cards are often...

Problems of smart card application development

Problems of smart card application development The development of smart card applications has always been a long and time-consuming process. The cards have the same size and appearance, they use a standardized communication protocol. Despite this, smart cards of different manufacturers have different internal “stuffing”. Most of the development tools are issued by smart card manufacturers. They usually include general assembly language programming tools and specialized hardware emulators that can be purchased from chip vendors....

A brief history of smart cards

EMV in e-commerce systems

At the moment, it makes no sense to define the term “e-commerce” itself, since over the past 5-7 years there has been a qualitative leap in the development of systems through which customer service is provided through open communication channels. First of all, it should be noted that two large classes of e-commerce systems have appeared: commerce on the Internet (e-commerce) and commerce using mobile phones (m-commerce). The fact is that historically, the development of the Internet and mobile operator services has occurred in...

Rules for using EMV cards at an ATM

Technology of production of EMV cards

Payment card as a technological product Payment cards from the point of view of manufacturing technology and operating principles are divided into magnetic stripe cards, microprocessor cards (other names are “smart cards”, “chip cards”) and optical memory cards (laser). Let’s consider the main points of the technology of manufacturing and functioning of each of the varieties of modern cards, as well as the technology of production of blanks, from which cards are then made. Technology of production of magnetic...

Risk assessment for EMV cards

The requirements of the IPU relate primarily to off-line monitoring, other monitoring options are not mandatory at the moment. In this regard, the bank should develop its own risk management policy in the PS and choose the monitoring system that corresponds to the adopted policy, and not just implement the most functional technical solution at the moment.
