Did you notice recently how people exchange their details with just a tap of the card touching the phone?
Did you think about what makes it possible to pay at the shop using a contactless card?
Charles Walton invented this technology in 1983 when he submitted the first patent with the term RFID.
In 2002, NFC first made headlines and subsequently was developed.
So what is NFC?
NFC or near-field communication is a connecting technology that works to exchange information with a tap.
The technology is known as RFID, or “Radio Frequency Identification,” forms the foundation for NFC. NFC was accepted as an ISO/IEC standard in 2003. The fundamental idea of RFID has been carried over to NFC.
Regarding NFC, there are two parts: the reader and the tag.
The tag is a tiny chip encased in a coil, and the reader is in charge of transmitting an electromagnetic signal (13.56MHz). The radio signal’s electromagnetic wave causes a little electric current to flow through the coil when it strikes the tag. This current is just enough for the tag to deliver the reader a little amount of data. It’s a technology standard based on radio frequency identification also known as RFID. It does not need an internal power source to function and can send information wirelessly over small distances.
As a result, NFC opens up new possibilities for consumer goods. RFID and NFC are closely related which can cause some confusion over when to use one over the other. We will write a separate article about it but to give a general idea.
NFC is best used to transfer a range of data over short distances. Its prevalence in access control and payment applications.
RFID is more suited to faster-moving environments. It is most often used for vehicle access control and asset management purposes.
NFC tags usually take the form of a sticker.
Each sticker is made up of two components that work together to form a functional device. Those are the antenna and a small system on a chip. Due to the relatively small amount of memory available NFC tags usually contains URL or other text records. From a user perspective, NFC works like magic. To interact user’s device you will need to bring it within range of an NFC tag and it is immediately presented with the corresponding content.
Across devices from iPhone to Android while most phones are equipped to read NFC tags.
Since 2006 when the first devices to support NFC were released the number of new devices supporting the technology has grown rapidly. According to the IHS technology, 2.5 billion NFC-enabled smartphones are used in 2022. Apple further opened NFC possibilities in 2017 when it began allowing NFC capabilities. Apple pay is now fast-forwarded to iPhones that support iOS 11 and up. Without additional apps, NFC has many impressive use cases.
Due to its versatile form factor, cheap cost and convenient scalability these use cases are broken down into a few main categories:
Services like Apple pay and Google Wallet make shopping simple with the tap to buy and added security. Because NFC chips are built into the physical products, the item can become its payment terminal. With just a tap, customers can interact with an embedded product to buy.
Pairing Bluetooth devices or connecting to a new Wi-Fi network can be a real pain especially if you forgot the password. NFC tags remove these issues by pairing devices with the top. Because NSE chats can store passwords securely they can relay pairing information. They’re a great way to connect the phone to a Wi-Fi network or Bluetooth speaker. This method is not only easier for users but also secure because passwords are transmitted without the need to write them down.
Apple watch uses NFC to pair itself to gym equipment for a more accurate workout. Supported machines allow the health app to synchronise heart rates, distance travelled and calories burned between the watch and the machine. Apple calls this functionality gem kit and is rolling out support to high-end gym equipment.
Posters and tourist destinations with NFC tags that, at user request, give information on smartphones are becoming more popular nowadays. For instance, if held up to an NFC-enabled concert poster, the phone can launch a website where tickets can be bought.
Using NFC, users may share links and contact details as well as data between devices. The smartphone display can be projected to the TV screen and photographs are transferred from the digital camera to the smartphone.
Electronic key fobs
We use NFC technology in the smart home. Without a physical key, users can open and unlock doors with NFC-enabled devices. This type of key has the benefit of being simple to provide to other parties. The matching lock has an NFC tag reading a smartphone or wearable device. Commercial and residential blocks use this feature to allow authorized personnel to access buildings. Additionally, the automobile industry uses NFC technology in digital automobile keys.
The same technology we use to verify user products and ensure content exclusivity.
Scalable product authentication legitimate product embedded with NFC at the factory. It has given a unique digital identity that customers can verify before buying.
It also makes it easy for retailers and brands to discover fake merchandise before it reaches unsuspecting customers.
Exclusive content enabling is more than authentication products.
NFC can also provide exclusive content to customers using NFC.
This exclusivity allows things like tickets videos and more, including buying and transforming fiscal items into a multi-channel experience.
This opens up new possibilities for brands and consumers.
Rolling code is used to ensure only those with the original product can access the content.
The rolling code is the code that rotates and changes each time an NFC taps the chip. The server will notify the owner of the brand or the customer that the product is fraudulent if it finds the same rolling code. NFC chip UID is a unique identifier provided by the manufacturer that is read-only and used to uniquely identify the tag in a project’s software systems. The UID is a crucial component of NFC security and clone prevention.
Using an NFC tag can stimulate the public’s interest and keep them on the premises for an extended period.
Cross-selling is a practice used by merchandise when customers tap their smartphones on an NFC-embedded product. They are directed to a landing page that shows them a list of products similar to their purchase or based on their cohesive interest.
One of the most powerful features of NFC is security and NFC payments are more secure with the rolling code.
Additionally, there are more methods to incorporate NFC technology into Smart Homes and daily life. On write-capable tags in the form of stickers or pendants, certain commands and functions can be programmed. Users may put their business cards or WIFI access information on the tag, for instance. A visitor is immediately logged into the network when he holds his smartphone near the tag. Unlike with a QR code, it’s not even essential to activate the phone’s camera to do this.
Digital business cards
The NFC exchanges information from digital business cards efficiently. This quick data transfer solves the inconvenience of one-to-one communication when people exchanges business cards. The system can provide people to exchange contact information one-to-one by using a digital business card system that consists of a server and a database based on NFC communication. Modern business cards have been developed to collect business card information from an NFC reader and transfer it to a smartphone application. These can simplify life for people who frequently forget to bring their business cards. no longer need to worry about carrying your cards around with you thanks to NFC intelligent cards. With just one tap, you may post your name, vCard, website address, or business’ Facebook page.
At Artorian we make it all included and the landing page will allow you to save all the details. Additionally, the content management system allows users to change the details whenever they want
A corporation can now provide their employer with smart cards including their personal information and access codes. To write data to your smart card, use the businesscontact admin access.
NFC tags are small durable lightweight and inexpensive.
Embedded into physical products that would otherwise have no digital connectivity.
Once fitted with NFC the products can drive to online content with a tap connecting the physical and the digital world.
