ISO 15693

ISO 15693 is an international standard for vicinity RFID (Radio-Frequency Identification) cards and tags, operating at the frequency of 13.56 MHz. It specifies the air interface protocol for communication between NFC transponders (also known as tags or chips) and NFC readers. The standard is maintained by the International Organization for Standardization (ISO) and is widely used in various applications including access control, inventory management, asset tracking, and electronic payments.

Here are some key aspects of ISO 15693:

1. Operating Frequency

ISO 15693 operates at 13.56 MHz, which is a globally recognized frequency band for NFC communication.

2. Contactless Communication

It defines the communication protocol for contactless communication between the NFC reader and the NFC transponder. This means that the communication can occur without direct physical contact between the reader and the tag.

3. Anti-Collision Mechanism

ISO 15693 incorporates anti-collision mechanisms that allow multiple tags to be addressed and read simultaneously, thus improving the efficiency of the system in scenarios where multiple tags are present within the reader's range.

4. Data Transfer Rate

ISO 15693 supports data transfer rates up to 26.48 kbit/s, enabling relatively fast communication between the reader and the tag.

5. Read/Write Capabilities

ISO 15693 tags can typically support both read and write operations, allowing data to be both read from and written to the tag.

6. Memory Capacity

The standard defines the structure for addressing memory within the RFID tags, allowing for storage of various types of data depending on the application requirements.

7. Security Features

While ISO 15693 itself does not define specific security features, it allows for the implementation of additional security measures such as encryption and authentication to ensure the integrity and confidentiality of the data transmitted between the reader and the tag.

8. Application Areas

ISO 15693 is widely used in various applications including asset tracking, inventory management, library systems, electronic ticketing, and contactless payment systems.

Overall, ISO 15693 provides a standardized framework for implementing RFID technology, enabling interoperability between different vendors' products and ensuring compatibility across different applications and industries.
