Near-Field Communication (NFC)

Sep 23,  · Near-field communication (NFC) is a short-range wireless connectivity technology that lets NFC-enabled devices communicate with each other. NFC began in the payment-card industry and is evolving to. Near field communication, abbreviated NFC, is a form of contactless communication between devices like smartphones or tablets. Contactless communication allows a user to wave the smartphone over a NFC compatible device to send information without needing to touch the devices together or go through multiple steps setting up a connection.

NFC or Near Field Communication is a protocol that helps two devices communicate wirelessly when they are placed right next to each other—for instance, smartphones or smart watches can be used for payments or boarding passes. NFC hardware is being included in more and more devices — particularly smartphones, but also some laptops.

NFC could be the future of payments, security keys, and boarding passes. NFC is also an upgrade over clunky QR codes.

NFC is a set of standards that allow smartphones and other devices to communicate via radio signals when they are held in close proximity. For example, if you had two NFC-equipped smartphones, you would touch them together back-to-back.

An NFC-equipped smartphone could be touched to or waved over an NFC-enabled payment terminal to pay for something, replacing the need for a credit card. How does too much cortisol affect the body Francisco has NFC parking meterswhich allow people to pay for parking by tapping an NFC-equipped phone against the parking meter.

Touch two phones back-to-back and the content being viewed on one device will be sent to the other. Anyone can purchase NFC tags, which are fairly cheap. You can configure the action that occurs when your smartphone comes in contact with the NFC tag.

Instead of doing this manually each night, you could put an NFC tag on your bedside table. When you go to bed, you can place your smartphone onto the NFC tag and your smartphone will perform an action you can configure, such as automatically enabling silent mode. These are just a few examples — you can perform any action an app on your smartphone can execute. Image Credit: Nathanael Burton on Flickr. Image Credit: mac morrison on Flickr. This is just a snapshot of what NFC is currently being used for.

Sep 23,  · NFC stands for Near Field Communication. NFC is a set of standards that allow smartphones and other devices to communicate via radio signals when they are held in close proximity. NFC works similarly to RFID, although NFC has a much shorter range than RFID. NFC’s range is about 4 inches, making it harder to eavesdrop on.

Near-field communication NFC is a short-range wireless technology that makes your smartphone, tablet, wearables, payment cards, and other devices even smarter. Near-field communication is the ultimate in connectivity. With NFC, you can transfer information between devices quickly and easily with a single touch—whether paying bills, exchanging business cards, downloading coupons, or sharing a research paper.

Near-field communication transmits data through electromagnetic radio fields to enable two devices to communicate with each other. To work, both devices must contain NFC chips, as transactions take place within a very short distance. NFC-enabled devices must be either physically touching or within a few centimeters of each other for data transfer to occur. Because the receiving device reads your data the instant you send it, near-field communications NFCs greatly reduce the chance of human error.

Rest assured, for example, that you cannot purchase something unknowingly because of a pocket-dial or by walking past a location that's embedded with an NFC chip called a "smart poster". With near-field communication, you must perform an action intentionally. As with any evolving technology, retailers need time to ramp up their equipment to be able to process NFC transactions; so for now, consumers should still carry cash or payment cards. In fact, even after NFC technology becomes universal, users may still need to carry a backup payment method; you cannot do much of anything with a device whose battery is drained.

Whether this would be a permanent downside to NFC technology, however, remains to be seen. Perhaps near-field communication is best known as the technology that lets consumers pay retailers and each other with their cell phones.

Take wanting to tap-to-pay for a pizza or anything that you just ordered through the Echo, for example. Near-field communication technology is rooted in radio-frequency identification RFID , which has been used for decades by retailers to tag and track products within stores. In , the Forum formally outlined the architecture for NFC technology, whose specifications continue to provide a road map for all interested parties to create powerful new consumer-driven products.

Nokia released the first NFC-enabled phone in , and by , the telecommunications sector had launched more than NFC pilot projects. With its ever-expanding boundaries, near-field communications have a wide variety of uses beyond simplifying and accelerating the payment process. Today, hundreds of millions of contactless cards and readers worldwide use NFC technology in myriad applications—from securing networks and buildings to monitoring inventory and sales, preventing auto theft, keeping tabs on library books, and running unmanned toll booths.

NFC is behind the cards that we wave over card readers in subway turnstiles and on buses. It is present in speakers, household appliances, and other electronic devices that we monitor and control through our smartphones. Near-field communications are proving useful in numerous industries and have far-reaching implications.

The customer experience in airports that use NFC technology is enhanced significantly, as NFC can shorten the boarding of a person plane to just 15 minutes—a process that normally takes 40 minutes without the use of NFC. In the hospitality industry, a hotel may manage building and room access centrally in real-time, without the need for physical delivery of key cards.

Using NFC technology, a hotel can send access rights to a guest's room directly to his or her mobile device in advance of their arrival. An NFC hospitality application can include other functions, too, such as booking the room and skipping the check-in phase. Blockchain Technology.
