Whether you're an industry expert or simply interested in learning the basics of RFID and NFC, RFID Communication Standards are the first thing you must know. While RFID technology is quite versatile and offers easy to use communication protocols for tag and reader communication and data capture, it has distinct wireless communication standards for UHF, HF/NFC and low frequency RFID communications. And it makes sense.
The ISO/IEC 15693 is a widely used standard for high-frequency (HF) and near-field communication (NFC) communication. ISO/IEC 15693 defines the protocols and parameters for contactless integrated circuit cards and other devices operating at 13.56 MHz.
In the RFID world, a flexible and efficient communication framework that facilitates data exchange between readers and tags is crucial to keep the cost of RFID implementation at lowest and affordable and that is why ISO/IEC and EPCGlobal have defined simple, easy to follow communication protocols. From inventory management to access control systems, these standards have paved the way for enhanced security, efficiency, and convenience across various industries.

The ISO/IEC 15693 standard enables communication between readers and tags using the principle of inductive coupling. It allows for bidirectional data exchange and supports anti-collision mechanisms, enabling multiple tags to be read simultaneously. The standard also defines various commands and response formats, ensuring interoperability between different manufacturers' products.
In terms of physical characteristics, ISO/IEC 15693 specifies the modulation and coding schemes, as well as the air interface protocols. It defines the frame structure, bit rates, and data coding schemes, providing a foundation for reliable and efficient communication. These specifications make ISO/IEC 15693 suitable for a wide range of applications, including asset tracking, logistics, and contactless payments.

Comparison between ISO/IEC 15693 and other RFID standards
While ISO/IEC 15693 is a widely adopted RFID communication standard, it is essential to understand how it compares to other standards to make informed decisions regarding system implementation. Here, we compare ISO/IEC 15693 with two other prominent RFID standards: ISO/IEC 14443 and ISO/IEC 18000-3 Mode 3.
1. ISO/IEC 14443: ISO/IEC 14443 is another widely used RFID standard, commonly employed in contactless smart cards and NFC-enabled devices. While both ISO/IEC 15693 and ISO/IEC 14443 operate in the 13.56 MHz frequency range, they differ in their communication protocols and target applications. ISO/IEC 14443 is primarily focused on secure, close-range communication, making it suitable for applications such as access control, public transportation tickets, or mobile payments. On the other hand, ISO/IEC 15693 is designed for longer-range communication and supports anti-collision mechanisms, making it ideal for applications such as inventory management or asset tracking.
2. ISO/IEC 18000-3 Mode 3: ISO/IEC 18000-3 Mode 3, also known as the "Active RFID" standard, is designed for long-range communication and operates at frequencies between 433 MHz and 928 MHz. Unlike ISO/IEC 15693, which relies on inductive coupling, ISO/IEC 18000-3 Mode 3 utilizes radio waves for communication. Data transfer rates and read ranges vary due to the differences in communication technologies. ISO/IEC 18000-3 Mode 3 is commonly used for applications such as vehicle identification, supply chain management, or industrial automation where longer reading distances are required.
To conclude, HF RFID, NFC, and ISO/IEC 15693 provide the essential communication standards that promote interoperability and efficiency. It ensures that devices can seamlessly communicate for diverse applications in access control, inventory management, and contactless payments.
