NFC Standard ISO/IEC 18000-3
The Near Field Communication (NFC) ISO/IEC 18000-3 standard defines the requirements for Radio Frequency Identification (RFID) for item management. It is actually Part 3 of the ISO/IEC 18000 standard. You need to consider only Part 3 when working with NFC. The standard has a number of goals:
- Define rules for communication between devices using frequencies that are available in any country.
- Specify the same set of rules for every acceptable frequency so that moving from one frequency to another doesn’t pose technical problems.
- Reduce both software and implementation costs.
- Create a common method for performing system management and control, and information exchange tasks as much as possible.
This standard defines three modes of operation. The modes don’t interoperate with each other, but they also don’t interfere with each other. In short, the modes are completely separate. Each mode defines different speed characteristics for transferring data between devices using differing signal-encoding techniques. Because the mode transitions occur automatically, you don’t really need to know much more than that they offer different speeds.
