Near-Field Communication(NFC)

 NEAR FIELD COMMUNICATION 

    Near-Field communication(NFC) is sending data over radio waves. a communication between two electronic devices over a distance of 10 cm or less.

                                     

                                                                                                                                NFC technology was initially inspired by Radio frequency identification(RFID).NFC is implemented to make the connection faster nowadays NFC is used in many smartphones and credit cards to make faster payments.

        In NFC we can send and receive communication messages but in RFID we can send but we cannot receive any message.   

        Nowadays mostly we are using share it, google files,xender, etc.these apps are based on wifi direct. with this NFC we can make the data transfer as much faster.

                                     

 

NFC Tags:

       

NFC tags are passive devices, which means that they operate without a power supply of their own and these tags will get active when the NFC paired device comes into range and it will be turned off when the paired device exceeds the range. In order to power these NFC tags, electromagnetic induction is used to create a current in the passive device(NFC tags). This is very similar to the techniques used for wireless charging technologies.

By using this NFC tags

• Wifi, Bluetooth can be turned on and off using this NFC tags, and also by using these tags we can share our password also.
• with the use of this NFC tags we can remotely control our computer and mobile phones We can easily share photo, videos, multimedia, documents etc..,
• With these NFC tags, we can also share live directions.
• Launch an application on someone's mobile phone with these NFC tags.
• By using these NFC tags we can also make payment in which the credit card is embedded with NFC.
