What is NFC PPT?

NFC or Near Field Communication is a short range high frequency wireless communication technology. NFC is mainly aimed for mobile or handheld devices. A radio communication is established by touching the two phones or keeping them in a proximity of a few centimeters (up to 10 cm) .

How does NFC work?

NFC tags work like any other RFID tag to communicate over radio waves. Two devices — the NFC tag and the NFC reader exchange information in NFC data exchange format. An NFC tag sends radio waves to activate the antenna in a receiving device. The recipient validates the information to complete information exchange.

What is an NFC device?

Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4cm or less to initiate a connection. NFC allows you to share small payloads of data between an NFC tag and an Android-powered device, or between two Android-powered devices. Tags can range in complexity.

What is NFC PDF?

Near Field Communication (NFC) technology is a new wireless short range communication technique for data transmission between intelligent devices such as mobile phones by integrating a small NFC reader into the cellular phones. This new technology supports the communication link within distance of up to 4 cm.

What is NFC in IoT?

In many cases, these services are powered by a method of wirelessly transferring data called near-field communication (NFC). NFC isn’t just useful on its own—it can also be used in conjunction with other cutting-edge technologies such as the Internet of Things (IoT).

What is the difference between near field communication and ultra wideband?

A near field communication (NFC) is a very short-range wireless connectivity technology made for cell phones and credit cards, while the ultra wideband (UWB) is a form of short-range communications that employs extremely short electromagnetic pulses that are transmitted across a broad range of radio frequencies.

What are the examples of NFC?

Examples of NFC

  • mobile payments, such as Apple Pay and Google Pay;
  • transit card payments;
  • ticket redemption at a concert or theater;
  • access authentication for doors or offices;
  • unlocking car doors or rental scooters;
  • venue or location check-in to alert friends on social media;

What are the types of NFC devices?

There are two main types of NFC devices: Passive communication NFC devices and active communication NFC devices. Passive devices have no power source and can only connect to active devices.

Why NFC is the future?

NFC can be the future medium of contactless electronic payment as it inhibits eavesdropping on NFC – enabled transactions pertaining to its short range, however range can be extended by attackers using some range extension system.

What are the advantages and disadvantages of NFC?

In this guide, we take a look at the pros and cons of NFC as a contactless or mobile payment portal.

  • Convenient—easy to make payments without a wallet or credit card.
  • Versatile—works with more than just payment systems.
  • Seamless communication between devices.
  • NFC payments are generally more secure than credit cards.

What are the types of NFC?

Where is NFC used?

NFC is the technology in contactless cards, and the most common use of NFC technology in your smartphone is making easy payments with Samsung Pay. NFC can also be used to quickly connect with wireless devices and transfer data with Android Beam.
