NFC Technology NFC Technology Near Field Communication

(NFC) is an evolution of contactless and short-range radio frequency identification (RFID) technologies.

NFC enables easy and intuitive ways of using mobile phones with touch-based technology –operating at a distance of only a few centimeters.

NFC is based on pre-existing contactless

payment and ticketing standards that are used on a daily basis by millions of people and devices

History:1983 Abbreviation of RFID-2004 Establishment of The Near Field

Communication (NFC) Forum.2006 Initial Specifications for NFC Tags.2009 In January, NFC releases Peer-to-

Peer Standards.2010 First Android NFC Phone2011 Demonstration of NFC By 2011 NFC-enabled mobile phones are

expected to reach 500 million worldwide.

Benefits & Features:Not restricted to 1-to-1 communicationMultiple devices in a small area can

communicate with each other using the same frequency.

Maximum transfer bit rate of 800kbps.No special software is required.Operation at a frequency of 13.56 MHz

range.Compatible with today’s field proven RFID technologyOperating distance of up to 20 cm, typically even less.

SYSTEM OVERVIEW:

METHODOLOGY:Secret code is entered from the keyboard.

Decoder connected to the keyboard will read this number and if the number entered is correct then the number decoder will trigger the MC whose output will go high.This high output will activate the reading system.

NFC Modes:

Comparision:

NFC Communication modes:Active NFC mode

In active NFC mode, both the initiator and the target are using their own generated RF field to enable the communication.

INITIATOR SENDS COMMAND TARGET SENDS ANSWER

Passive NFC mode In passive NFC mode, the target answers to an

initiator command in a load modulation scheme. The initiator generates the RF field and target uses the RF field generated by the active device

Applications:Payment And Ticketing:

Advanatages of NFC:Ease of useDecreasing the amount of user made errorsCompatibilityVersatile technologyAbility to decrease or eliminate duplicate

workLess set up time

Disadvantages Of NFC:Easy to hackShort limited distance

Example:

Future Hardware Development:

Less power consumptionMore efficient loop antenna for larger range.

Smaller setup Two-way communication

Results:

Maximum bit rate of 800kbpsText communication between two PCs

Transmission range of 30cmAbility to send a text file between PCs

Conclusion:

•In summary, Near Field Communication is an efficient technology for communication withwith short ranges. •It offers an intuitive and simple way to transfer data between electronic devices.• A significant advantage of this technique is the compatibility with existing RFID infrastructures.
