NFC Insight

Smartphone Interface for RFID Tags

An NFC-enabled smartphone should also exist able to read RFID tags? Hardly conceivable considering until recently, in that location was a articulate technological separation betwixt classic RFID with its three variants (LF, HF, and UHF) and contactless information transmission via NFC: The maximum distance betwixt ii communication partners that must not be surpassed. Whereas, for RFID, this distance is greater than ten cm, for NFC, the components must well-nigh touch for data exchange. Withal, the idea of smartphones beingness able to read the huge number of RFID tags out there stimulated the NFC Forum to define their own NFC standards for this purpose, both for the protocol (NFC-V) and for the tags (Tag Blazon 5).

Proximity – RF Close Coupling Communication

A smartphone's NFC interface has been designed to collaborate with its close proximity. In club to make the contact equally easy as possible and still secure, the maximum distance of below 10 cm is deliberately very pocket-size. This minimizes the danger of triggering advice not wanted by the smartphone user. It just takes a few seconds touch to pay at a point of sale, to open a rental car or a hotel room. Due to this very small operating distance, this blazon of communication is called "proximity" advice. It is based on the ISO/IEC 14443 standard.

Vicinity – RFID Communication

There are three frequency bands for the performance of RFID systems: depression frequency, high frequency, and ultra high frequency. The RFID systems used in the unlike frequency bands differ with respect to their operating distance, the transmission rate, and interference liability. This results in very different apply cases. RFID is the most used identification procedure in warehousing, ware tracking, and freight logistics. The operating distance is defined every bit vicinity range, and thus significantly to a higher place that of NFC. RFID technology is specified by ISO/IEC 15693.

NFC-V: Vicinity Protocol Standard Express to Proximity Range

The signal specifications on which RFID and NFC are based are very similar. Especially the RFID engineering science that radios on the same carrier frequency every bit NFC (xiii.56 MHz) is so close to the NFC standard that both can be implemented on the same hardware. Thus, an NFC-enabled device does not need a new or a second contactless interface in club to be RFID-enabled.

Nevertheless, NFC-V is a kind of hybrid technology: The V stands for vicinity and highlights the fact that an NFC interface tin can now be used to read RFID components that were originally dimensioned for greater distances. Therefore, NFC-5 is not based on ISO/IEC 14443, merely on ISO/IEC 15693, the underlying standard of RFID. However, in order to avoid the integration of a new antenna for distances > 10 cm, the operating distance of NFC-V has been reduced to the typical NFC proximity distance of < 10 cm.

NFC Type 5 Tag: HF-RFID Tag for NFC

In order for RFID readers and NFC-enabled smartphones to communicate with the same tag, the NFC Forum divers a new class of NFC tags. And so-chosen NFC Blazon 5 tags tin can be modified past a smartphone every bit long as it is in close proximity to the tag. Then, the same tag can be read by any commercial HF-RFID scanner. Manufacturers, aircraft companies, retailers and consumers may get read or even write admission to the tag. This opens up new options for handling of goods on their way from manufacturer to end consumer:

Provision of product information for the terminate consumer,
Setup of anti-theft security systems,
Usage as tool for promotion,
Initiation and logging of payment transactions,
Tracking of goods in production, transportation, warehousing, and shops to name a few.

This intelligent connection of ii neighboring contactless communication systems ultimately turns NFC into a stiff promoter of the Internet of Things. Now, it is heady to see which innovative ideas will result from the implementation and usage of the IoT.

Lower ability requirements of blazon 5 tags enable smaller NFC antennas and a wider range of apply cases like ware tracking or fraud protection.
