ISO/IEC 14443-1:2018

ISO/IEC 14443-1:2018 Cards and security devices for personal identification — Contactless proximity objects — Part 1: Physical characteristics

ISO/IEC 14443-1:2018 is a new standard for contactless proximity objects. It specifies the physical characteristics of cards and security devices, including their size and shape. This article will provide you with an overview of the new standard, and explain the key changes that have been made.

ISO/IEC 14443-2:2020 Cards and security devices for personal identification — Contactless proximity objects — Part 2: Radio frequency power and signal interface

And ISO/IEC 14443-2:2020 defines the physical characteristics of contactless proximity objects, including radio frequency power and signal interface.

ISO/IEC 14443-3:2018 Cards and security devices for personal identification — Contactless proximity objects — Part 3: Initialization and anticollision

ISO/IEC 14443-3:2018 specifies the physical characteristics of cards and contactless proximity objects that are intended to be used in personal identification.

Contactless proximity objects are used in a variety of applications, such as access control, ticketing, and gaming. So, these objects can be used in conjunction with ISO/IEC 7816-4:2012 cards for authentication and payment.

Moreover, ISO/IEC 14443-3:2018 specifies the initialization process for contactless proximity objects. This process is used to verify the cardholder’s identity and to avoid collisions between cards.

ISO/IEC 14443-3:2018 also specifies the anticollision mechanism for contactless proximity objects. This mechanism is used to prevent two cards from being used at the same time.

ISO/IEC 14443-4:2018 Cards and security devices for personal identification — Contactless proximity objects — Part 4: Transmission protocol

Physical characteristics of contactless proximity objects

ISO/IEC 14443-4:2018 defines the physical characteristics of contactless proximity objects and the transmission protocol used to exchange information between cards and readers. Contactless proximity objects are small, low-power devices that can be worn on the body or carried in a pocket. They can be used for example for card access control, electronic signature capture, and secure identification.

The physical characteristics of a contactless proximity object are determined by the type of transmission protocol used. In fact, ISO/IEC 14443-4:2018 provides four different transmission protocols: Near Field Communication (NFC), Wireless NFC (Wi-NFC), Bluetooth LE (BTLE), and Zigbee. Each transmission protocol has its own set of physical characteristics.

Near Field Communication (NFC) is a short-range transmission protocol that uses electromagnetic fields to communicate information between cards and readers. NFC is most commonly used for card access control and electronic signature capture.

Therefore, Wireless NFC (Wi-NFC) is a long-range transmission protocol that uses radio waves to communicate information between cards and readers. Wi-NFC is most commonly used for mobile payments and secure identification.
