NFC Times Exclusive Insight – The NFC Forum has introduced a specification for an NFC tag Type 5, supporting the ISO/IEC 15693 protocol, but the trade and standards group is not supporting the protocol’s longer range.
The forum announced the new specification today, after having earlier indicated the spec was forthcoming. It also announced three new candidate technical specifications.
The new Type 5 tag specification details requirements for how NFC devices, such as readers or mobile handsets, will communicate with ISO 15693-compliant tags configured to store NDEF messages. Such tags will join the forum's four other tag types, which are based on the ISO/IEC 14443 contactless standard. ISO 15693, sometimes referred to as the NFC-V option, is based on an RFID protocol for so-called "vicinity" cards, which has a range up to 10 times longer than the ISO 14443 standard, often referred to as the “proximity card” standard, which has underpinned the NFC communication standard to date. ISO 14443 generally calls for a 10-centimeter range.
