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.

EXTENDED REALITY(XR)

    w hat is   EXTENDED REALITY?                        AR , VR , and MR , and everything is in between are encapsulated in extended reality which is the short XR, by extended reality gives immersive experience than VR , AR , and MR .extended reality is the next evolution in human-computer and environment interactions. XR is the term for all physical and virtual combined environments and human-machine interactions . Technologies Fall Under XR                          Virtual Reality(VR) Augmented Reality(AR) Mixed Reality(MR) Virtual Reality:     while this Virtual Reality (VR) enables full immersive experience and block's out the physical world. Augmented Reality:     This Augmented Reality places digital holograms. Augmented reality(AR) does not directly interact with digital objects.because   of which Mixed Realit...

Encryption and Types

  what  is Encryption ?  Encryption  is the process in  which the information is converted into secret code that hides the information's true meaning.                                                                           In computers, encrypted data is called ciphertext(public-key encryption), and the unencrypted data is known as plaintext(secret-key  encryption) . The method used in encoding and decoding is called encrypting algorithms.                                                        Importance of Encryption Encryption plays an important role in securing many different ty...

WIRELESS CHARGING

What is  Wireless Charging And How Does It Work?   wireless charging,  it has been around since the late 19th century, NikolaTesla demonstrated  magnetic resonant coupling  – the ability to transmit electricity through the air by creating a magnetic field between two circuits, a transmitter and a receiver.                                                                 Wireless Charging Nowadays charging technology is getting big this is why charging technology Is all the rage now, and the new big thing is wireless charging .it's just convenient to use. Near the end of the 19th century, engineering mastermind Nikola tesla showed that two powerful magnetic fields can slightly transfer energy between their sources when they interfere with each other. but this wireless char...
