NFC (near-field communication) is a short-range communication technology which has seamlessly integrated into our daily lives, offering various applications that simplify tasks and enhance user experiences. From contactless payments, information sharing, and access control to smart home automation, NFC devices are used for simplifying our lives in various distinct ways.
Near Field Communication: Things to Know
NFC was invented by Sony and NXP Semiconductors in 2002. After that, Nokia, Philips, and Sony collaborated to launch the NFC Forum to add further technological advancements in NFC technology in 2004. The NFC forum has previously helped large multinational corporations (MNCs), like Samsung and Apple, use NFC technology to create a secure contactless payment service for their smartphones. They have contributed to the commercialization of NFC across a range of industries.
Near Field Communication (NFC) is all around us in the form of either a smartphone feature or NFC-based credit and debit cards, smart cards for access control or identity cards. Let’s see more ways NFC is used in our day-to-day lives:
Top 10 Ways NFC is used in Everyday Life
NFC technology allows devices to wirelessly exchange data with other NFC-supported devices. Here are the top 10 ways NFC is used in everyday life:
1. NFC used in cars
NFC in a car can be very helpful to you. If you place an NFC tag in your car, turn on the Bluetooth system of the car whenever you hop on.

NFC facilitates seamless information exchange by establishing a peer-to-peer connection between two NFC-enabled devices, such as smartphones, tablets, laptops, or speakers. Tapping two NFC-enabled devices together enables users to share contacts, photos, or text files.
6. Product Authentication
NFC helps in verifying the authenticity of a product. An NFC tag contains a unique ID number for each item, which helps the manufacturer track and traces each product easily. Consumers can also tap their smartphones on NFC tags to access information about the product's origin, ensuring trust and transparency. NFC tags prevent products from counterfeiting and tampering.
7. Bluetooth Pairing with NFC
NFC enables a fast and accurate pairing of Bluetooth devices. For example, it is a quick and reliable way to pair a smartphone with Bluetooth speakers. It doesn't require any manual setup; you just need to make sure that Bluetooth and NFC are enabled on both devices. Bluetooth pairing allows devices to connect with a simple tap.
8. Public Transportation with NFC
NFC technology can simplify our everyday travel, from buying tickets to boarding public transport. NFC cards or mobile apps in public transportation systems simplify our everyday commute. Users can swiftly tap their cards or phones to access buses, trains, or subways, transforming the way we travel.
9. Interactive Marketing with NFC
NFC technology provides an interactive marketing solution. It is a proximity-based marketing strategy that uses NFC tags to interact with a physical object. The marketing team can create an interactive advertisement with the help of NFC stickers on signage and banners. A consumer can access the information on the item through ads, photos, or videos by tapping on the sticker.
10. Healthcare facilities with NFC
NFC technology in healthcare facilitates a fast registration process for patients, provides secure patient identification, and collects real-time data from patients. NFC has been used in healthcare for a variety of applications, including home monitoring, medication, and product authentication.
To conclude, NFC technology provides improvements in various sectors to enhance our quality of life. Near-field communication is helping users by simplifying everyday tasks such as contactless payment making, smart home automation, and information sharing through NFC, public transportation, and healthcare facilities.
