  2. 2. Outlines  Introduction  History  why we need this technology,  what this technology is trying to solve, NFC work The issues and solve these issues,  advantage and disadvantage Implementation Research area future Apply this technology
  3. 3. The last few decades the development of new communication technologies has exploded .One of the newest wireless technology is Near Field Communication (NFC) which is an extension of Radio Frequency Identification (RFID).It uses magnetic field induction to enable communication between electronic devices by touching themselves .It used for contactless short-range communication of ten centimeters.
  4. 4. ~ NFC roots back to radio-frequency identification (rid). RFID is a technology which uses radio frequency signals to transmit small amounts of data. ~ In 2002 Phillips and Sony was started work on NFC ~ In 2004, NFC became an accepted Information Communication Technology. ~ In February 2013 Visa and Samsung entered a partnership, where they together are developed better payment options using NFC .
  5. 5. BACKGROUND NFC stands for Near Field Communication implemented as a chip in a mobile phone or other mobile device or in a card. NFC is short-range wireless connectivity technology. NFC is set of standards for smart phones to establish communication with each other and close together. That enables objects, such as mobile phones, computers, tags, or posters, to exchange information wirelessly across a small distance. Currently, mobile phone manufacturers like Nokia, HTC, Samsung, RIM (Blackberry), banking institutions and mobile network providers are attempting to apply this technology.
  6. 6. operates at a frequency of 13.56 MHz, Data transfer rate is slow, which is up to 424 Kb per second .  NFC allows contactless and secure dual-way communication between two electronic devices within close proximity. No need to set-up can be established communication quickly and easily. It mainly aimed for mobile or handheld devices .  The distance allowing for communication between NFC devices is between three to ten centimeters this provided high degree of security . WHAT IS NFC
  7. 7. Why we need this technology ?  It is a modern technology contributed in facilitate routine transactions in everyday life it enables devices to communicate with each other with less effort and less price and more secure .  It is suitable for roaming at all times. NFC is a hassle free communication. NFC work with RFID tags .
  8. 8. Solutions and Facilities * More secure than RFID and Bluetooth, protect from hackers because it is short range. * share information, and easier to use transport and other public services. * Near Field Communication ( NFC ) technology makes our life easier by
  10. 10. How this technology work ?  Near field communication, or NFC for short, is an offshoot of radio-frequency identification (RFID) with the exception that NFC is designed for use by devices within close proximity to each other(10 cm). the physics principle for NFC/RFID is a Magnetic induction.
  11. 11. Active mode vs Passive mode Active mode  The sender and receiver has the ability to send and receive from each other which means that they owns Passive mode power source .  Only one device from two can be emit a current that is mean send data , while The other device is powered solely by the current created by the

  13. 13.  Eavesdropping  Data Corruption  Data Modification  Data Insertion  Man-in-the-Middle-Attack SOLUTIONS
  14. 14.  Convenience ADVANTAGES  Safety & NFC is Suitable for non technical users because it is provide automatic DISADVANTAGES connections without need to set up.  NFC is interoperable globally , such as payment from anywhere around the world.  Company Agreements to use NFC.  Security .  Not all the cell phones are compatible with NFC technology Lack of education
  15. 15. IMPLEMENT THIS TECHNOLOGY • Firstly, NFC technology is evolving continuously, appearing in all areas of life and make your life easier. • NFC devices can operate in three different modes: 1) Read/Write 2) Peer to Peer emulation 3) Card
  16. 16. PAYMENT SYSTEMS  Google Wallet Google Wallet (as digital wallet) it is payment system developed by Google that securely stores your credit cards, debit cards, offers ,and more With Google Wallet, you can send money, shop in stores, and buy online uses near field communication (NFC) .
  17. 17. WORK OF GOOGLE WALLET  Use it Online  Use it in-Store
  18. 18. RESEARCH AREAS FOR NFC TECHNOLOGY  Security NFC vulnerable to attacks that threaten either the security of information exchanged between the transmitter and the receiver, or the user's privacy or other attacks.  Usability a. NFC in Context of Human Computer Interaction. b. NFC and Ubiquitous Computing. c. Design of NFC Phones.  Reliability it is important field that NFC technology provide it during transfer data between devices
  19. 19. Cont …  Marketing Facilitated the process of marketing to customers, instead of carry a bank cards only customer using Mobile for payment.  Performance NFC performance better than Bluetooth .  flexibility NFC technology provide The flexibility of different data types to be stored on the NFC tag , it does not require an additional app to transfer information

  22. 22.  In the future, near field communication technology has the potential to become a staple of our daily lives, it will be adopted worldwide.  In the future, NFC is hoped to expand from mobile payments to Student ID cards Punch cards, Alternative to keys, gaming systems
  23. 23. Near field communication (NFC) is an efficient technology for communications with short range. it provides a simple way to transfer different types of data between electronic devices. this technology is still at the beginning of the journey, it is still under development to become one of the most important techniques in the near future .
