Introduction
Near Field Communication(NFC)
• NFC is a short range wireless technology based on RFID
• NFC operates on 13.56 MHz frequency
• Compatible with existing RFID Infrastructure
• Range (<= 10 cm theoretical, 1-4 cm typical)
• Data transmission rates such as 106kbps, 212kbps, and 424kbps
• Setup-time < 0.1 Sec

NFC Communication Modes
• Active device(Initiator): A device that generates its own RF field.
Example: NFC enabled mobile and NFC Reader.
• Passive Device(Target): A device which uses the RF field created by an
active device. Example: NFC Tag and NFC enabled mobile.
• Active Mode : In active communication mode, both devices generate their
own RF field to exchange data.
• Passive Mode: In passive communication mode, only one device
generates an RF field, while the other uses load modulation to transfer
data.

NFC Operating Modes
Reader-Writer Mode
• An active NFC device reads and writes passive NFC cards/tags.
• Tag content: Text, URI (Web Link, Phone Number), Smart Poster.
• Applications:
-Mobile Coupons
-Information access
-Smart Posters
• Industrial Applications:
-Asset Management
-Maintenance systems
-Product Genealogy [2]

NFC Operating Modes
Peer-To-Peer Mode
• Peer-to-peer mode provides easy bidirectional data exchange between
two NFC Devices.
• P2P mode Provide secure exchange of private data in a few centimeters
• Applications :
- Health Monitoring [1]
- P2P Payment
- Bluetooth Pairing
• Industrial Applications :
- Industrial motor with NFC
Control [4]
- Automobiles in ignition [5]
- Controlling Sensors [6]

NFC Operating Modes
Card Emulation mode
• Tag emulation mode is the reverse of reader/writer mode
• In this mode the NFC enabled device acts in passive mode.
• A NFC device acts as contactless smartcard and is being recognized by
existing NFC readers
• Applications :
-Transportation ticketing (Deutsche Bahn)
-Contactless logins and
authentication on computers
-Payments (Visa pay Wave, Google Wallet)
• Industrial Applications :
- Access control to Research Labs.

Localization based Point-of-Information
• Localization based Point-of-Information is to gather Information specific to
a particular Location.
• To get Information we need to browse through the PLC, DCS
• Accessing information of one particular small module is sometimes time
consuming.
• Advantages:
• Access Real time Information by a simple touch
• No Prior Knowledge is required
• Information can be obtained in less than a second.

Context aware user interface
• Why Context aware user interface ?
• Information Access From Plug and Play Modules
• Less Engineering Effort
• Less time Consumption
• Overcome Interoperable Issues
• Dynamic GUI

.
Continued..
• Data interchange format – JSON.
• Reduces impedance mismatch between database and web server.
• Because of the similarity between JSON and JavaScript.

Conclusion & Future work
• Use Cases of NFC in Industrial Automation is Demonstrated
• Advantages:
• Accessing localized Real time Information just by a simple touch
• Accessing Real time information of Plug & Play Modules.
• Future work:
• Peer to peer communication of NFC In Industrial automation.
• The architecture for generating context aware User interface
dynamically need to be implemented in real life scenario.
