NFC Forum Issues Specifications For Four Tag Types
WAKEFIELD, Mass., July 31, 2007 — The NFC Forum, a non-profit industry association that advances the use of near field communication (NFC) technology, today announced the publication of four tag type technical specifications. The specifications are available to the public for download at no charge from the NFC Forum Web site, here.
NFC is a short-range, wireless connectivity technology that allows consumers to perform safe, contactless transactions, access digital content, and connect electronic devices with the simplicity of a single touch. Consumers with NFC-enabled mobile phones may, for example, leave their wallets at home and use their phones to conduct contactless financial transactions, or to gain electronic access to public transportation.
Tags are integrated circuits that store data that can be read by NFC-enabled devices to support these applications. For example, a cinema goer with an NFC-enabled mobile phone may touch the phone to a movie poster containing an embedded NFC tag to view a preview of the movie.
By standardizing the tag types and formats with the specifications announced today, the NFC Forum is promoting interoperability across the NFC market, enabling low-cost volume production, and clearing a path to a global, cost-effective mass market. More than one billion NFC-ready tags are already deployed worldwide for use in areas such as accessing public transportation, hotel rooms, and offices.
It is essential to the adoption and growth of NFC technology that all NFC-enabled devices interoperate seamlessly and deliver a consistent user experience, said Christophe Duverne, Chairman, NFC Forum. By publishing these four tag types, the NFC Forum is taking great strides towards putting the power of NFC in the hands of consumers around the world.
Building on existing technology, the Forum’s tags are based on the International Organization for Standardization (ISO) 14443 Type A and B standards and Sony’s FeliCa. The four tag types are all based on existing contactless products and are available commercially.
The NFC Forum has mandated that the four tag types be operable with NFC devices. This mandate is the backbone of interoperability between NFC tag providers and NFC device manufacturers to ensure a uniform user experience. The tag specifications are the most recent in a series of specifications being developed by the NFC Forum. The NFC Data Exchange Format (NDEF) specification and four Record Type Description (RTD) specifications were released in 2006. These specifications are also available for download here.
The operation specifications for the NFC Forum tag types, numbered 1-4, provide the technical information required to implement the reader/writer and associated control functionality of the NFC device, enabling interaction with the tags. The four tag type specifications are:
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.
About Near Field Communication Technology
Near Field Communication (NFC) is a standards-based, short-range wireless connectivity technology that enables simple and safe two-way interactions among electronic devices. NFC technology allows consumers to perform contactless transactions, access digital content and connect devices with the simplicity of a single touch.
Near Field Communication (NFC) technology provides global interoperability of contactless identification and interconnection technologies. NFC operates in the 13.56 MHz frequency range, over a typical distance of a few centimeters. The underlying layers of NFC technology are based on ISO, ECMA, and ETSI standards. NFC technology is supported by the world’s leading communication device manufacturers, semiconductor producers, network operators, IT and services companies, and financial services organizations. NFC is compatible with hundreds of millions of contactless cards and readers already deployed worldwide.
