Dear Reader,

Near Field Communication (NFC) technology makes life easier and more convenient for consumers around the world by making it simpler to make transactions, exchange digital content, and connect electronic devices with a touch.

NFC is a wireless technology with set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Present and anticipated applications include contact-less transactions, data exchange, and simplified setup of more complex communications such as WiFi. Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag".

Dear Reader,

NFC requires a distance of 4 cm or less for communication. NFC operates at 13.56?MHz on ISO/IEC 14443 A/B, ISO 18092 etc. air interface and at rates of 106kbit/s, 212kbit/s and 424kbit/s, and higher rates are expected in the future. NFC has two modes of operation: Active and Passive.

In Active mode, both NFC devices generate their own radio fields to transmit data.

In Passive mode, one device generates radio field while the other uses load modulation to transfer the data.

NFC builds upon RFID systems by allowing two-way communication between endpoints, where earlier systems such as contact-less:good: smart cards were one-way only. Since unpowered NFC "tags" can also be read by NFC devices, it is also capable of replacing earlier one-way applications. A remarkably diverse and ever-expanding universe of NFC use cases is being explored and brought to market all around the world. Today, both research organizations and commercial enterprises are putting NFC to work in widely diverse areas.

Dear Reader,

NFC Tags:

These are small RFID chips and passive devices. Any NFC enabled active device can be used to communicate with it. These are manufactured by different companies and can have different sizes, shapes (circular and square) and format (paper sticker, anti metal, card format, key fob, tokens, and inlays). NFC Forum has standardized NFC tags into following four categories to cater for the broadest possible range of applications and device capabilities:

Type 1 is based on ISO 14443 A and was initially available exclusively from Innovision Research & Technology (Topaz™). Broadcom bought this company and now type 1 tags are not easily available. It has a 96-byte memory capacity, which makes it a very cost-efficient tag for a wide range of NFC applications

Type 2 is also based on ISO 14443 A and is currently exclusively available from NXP’s Mifare Technology (MIFARE Ultralight & Mifare Ultralight C). Mifare Ultralight has 48 bytes of user memory while Mifare Ultralight C has 132 bytes of user memory. These are widely used NFC tags across the globe and are available at quite low price.

Type 3 is based on FeliCa technology and is currently exclusively available from Sony. It has a larger memory (currently 2kbyte) and operates at a higher data rate (212kbit/s), which means it is suitable for more complex applications

Type 4 is fully compatible with ISO 14443A/B and is available from a number of manufacturers, including Philips (typical product example is MIFARE DESFire). It offers large memory-addressing capability with read speeds of between 106kbit/s and 424kbit/s – making it suitable for multiple applications.
