Smart Card Programming: A Comprehensive Guide by Ugo Chirico

Smart cards are small devices that can store data, perform operations, and communicate with other systems. They are widely used in various fields, such as payment, identification, access control, security, and telecommunications. Smart cards offer many benefits, such as portability, security, convenience, and interoperability.

However, smart card programming is not a trivial task. It requires a good knowledge of the technological aspects related to smart cards, such as their architecture, communication protocols, standards, specifications, and APIs. Moreover, it requires a good understanding of the application domains that use smart cards, such as payment systems, wireless communication, cryptography, and so on.

If you want to learn how to program smart cards effectively and efficiently, you need a comprehensive guide that covers all these aspects in depth. That's why you should read Smart Card Programming by Ugo Chirico.

Smart Card Programming is a book that offers a complete overview of the technological panorama related to smart cards. It provides an in-depth technical coverage of the architectures, programming paradigms, and APIs that are used to develop smart card applications. It also describes the main technologies that use smart cards, such as EMV, NFC, MIFARE, SIM/GSM, PKCS#11, JavaCard, Cryptography, and more.

The book is divided into two parts. The first part introduces the general concepts and some case studies related to smart cards. It is suitable for non-technical readers who want to get a high-level overview of the smart card world. The second part is a technical guide to smart card specifications and programming paradigms. It dives into technical topics about smart card programming and application development in C/C++, C#, Visual Basic, and Java.

The book is written by Ugo Chirico, an expert in smart card technologies with more than 20 years of experience. He has worked as a consultant, trainer, developer, researcher, and author in the field of smart card programming. He has also created several open source projects and tools related to smart cards, such as Virtual Smart Card, Smart Card Shell, and Smart Card Framework.

If you want to master smart card programming and learn how to create powerful and secure applications with smart cards, you should definitely read Smart Card Programming by Ugo Chirico. You will find all the information, examples, and resources you need to become a proficient smart card programmer.

Smart Card Technologies

Smart cards are not all the same. They differ in their physical characteristics, their capabilities, their communication protocols, and their standards. In this section, we will explore some of the most important aspects of smart card technologies that you need to know as a smart card programmer.

Contact and Contactless Smart Cards

One of the main distinctions between smart cards is whether they are contact or contactless. Contact smart cards have a metallic interface on their surface that connects to a reader through physical contact. Contactless smart cards have an antenna embedded in their body that enables wireless communication with a reader through radio frequency.

Contact smart cards are more reliable and durable, as they are less prone to damage and interference. However, they are also slower and less convenient, as they require physical insertion and removal from the reader. Contactless smart cards are faster and more convenient, as they only need to be brought close to the reader. However, they are also more vulnerable and limited, as they depend on the power and range of the reader.

Some smart cards can be both contact and contactless, depending on the situation. These are called dual-interface or hybrid smart cards. They have both a metallic interface and an antenna, and they can switch between them according to the type of reader they encounter.

ISO 7816 Specification

ISO 7816 is the international standard that defines the characteristics and commands of contact smart cards. It consists of several parts that cover different aspects of smart card technology, such as physical dimensions, electrical signals, transmission protocols, data structures, security features, and application identifiers.

The most important part of ISO 7816 for smart card programmers is part 4, which defines the organization and commands for interchange between a card and a terminal. It specifies how a smart card is structured into files and directories, how data is stored and accessed in these files, how commands are formatted and exchanged between the card and the terminal, and how errors are handled and reported.

ISO 7816 part 4 defines two types of commands: case 1 commands, which have only a header with no data; and case 2 commands, which have a header and some data. The header consists of four bytes: CLA (class), INS (instruction), P1 and P2 (parameters). The data consists of LC (length) and DATA (content) bytes for case 2 commands. The response from the card consists of SW1 and SW2 (status words) bytes that indicate the result of the command execution.

Some examples of ISO 7816 commands are: SELECT FILE, which selects a file or directory by its identifier; READ BINARY, which reads data from a binary file; UPDATE BINARY, which writes data to a binary file; VERIFY, which verifies a password or a PIN; GET CHALLENGE, which requests a random number from the card; INTERNAL AUTHENTICATE, which performs an authentication operation using the card's cryptographic keys; EXTERNAL AUTHENTICATE, which performs an authentication operation using the terminal's cryptographic keys.

Memory Cards and Microprocessor Cards

Another distinction between smart cards is whether they are memory cards or microprocessor cards. Memory cards are simple devices that can only store data in their memory. They have no processing capabilities or security features. They can be read from or written to by any compatible reader. They are cheap and easy to produce, but they are also insecure and limited in functionality.

Microprocessor cards are complex devices that have a CPU, RAM, ROM, EEPROM, and I/O ports. They can perform operations on data stored in their memory or received from external sources. They have security features such as encryption, authentication, access control, and tamper resistance. They can execute applications written in various languages or platforms. They are expensive and difficult to produce, but they are also secure and versatile in functionality.

Some examples of memory cards are: magnetic stripe cards, which store data in a magnetic band on their surface; barcode cards, which store data in a series of bars on their surface; optical cards, which store data in a series of holes or marks on their surface; RFID tags, which store data in an electronic chip that can be read by radio waves.
