NFC Forum Specifications Available
All publicly released NFC Forum technical specifications are available for download here.
Data Exchange Format Technical Specification
NFC Data Exchange Format (NDEF) Technical Specification
Specifies a common data format for NFC Forum-compliant devices and NFC Forum-compliant tags
Record Type Definition Technical Specifications
Technical specifications for Record Type Definitions (RTDs) and three specific RTDs: TEXT, URI, and Smart Poster.
NFC Record Type Definition (RTD) Technical Specification
Specifies the format and rules for building standard record types used by NFC Forum application definitions and third parties that are based on the NDEF data format. The RTD specification provides a way to efficiently define record formats for new applications and gives users the opportunity to create their own applications based on NFC Forum specifications.
NFC Text RTD Technical Specification
Provides an efficient way to store text strings in multiple languages by using the RTD mechanism and NDEF format. An example of using this specification is included in the Smart Poster RTD.
NFC URI RTD Technical Specification
Provides an efficient way to store Uniform Resource Identifiers (URI) by using the RTD mechanism and NDEF format. An example of using this specification is included in the Smart Poster RTD.
NFC Smart Poster RTD Technical Specification
Defines an NFC Forum Well Known Type to put URLs, SMSs or phone numbers on an NFC tag, or to transport them between devices. The Smart Poster RTD builds on the RTD mechanism and NDEF format and uses the URI RTD and Text RTD as building blocks.
NFC Forum Tag Type Technical Specifications
The NFC Forum has mandated four tag types to be operable with NFC devices. This is the backbone of interoperability between different NFC tag providers and NFC device manufacturers to ensure a consistent user experience.
The operation specifications for the NFC Forum Type 1/2/3/4/ Tags provide the technical information needed to implement the reader/writer and associated control functionality of the NFC device to interact with the tags. Type 1/2/3/4 Tags are all based on existing contactless products and are commercially available.
NFC Forum Type 1 Tag Operation Specification
Type 1 Tag is based on ISO14443A. Tags are read and re-write capable; users can configure the tag to become read-only. Memory availability is 96 bytes and expandable to 2 kbyte; communication speed is 106 kbit/s.
NFC Forum Type 2 Tag Operation Specification
Type 2 Tag is based on ISO14443A. Tags are read and re-write capable; users can configure the tag to become read-only. Memory availability is 48 bytes and expandable to 2 kbyte; communication speed is 106 kbit/s.
NFC Forum Type 3 Tag Operation Specification
Type 3 Tag is based on the Japanese Industrial Standard (JIS) X 6319-4, also known as FeliCa. Tags are pre-configured at manufacture to be either read and re-writable, or read-only. Memory availability is variable, theoretical memory limit is 1MByte per service; communication speed is 212 kbit/s or 424 kbit/s.
NFC Forum Type 4 Tag Operation Specification
Type 4 Tag is fully compatible with ISO14443A and B standards. Tags are pre-configured at manufacture to be either read and re-writable, or read-only. Memory availability is variable, up to 32 KBytes per service; communication speed is up to 424 kbit/s.
