Technology has seeped its way into our daily lives, with close to around 40% of the population having internet access globally, while the rest observe themselves making an entry almost daily online. This has been stated according to a report by the World Development Report.
This, therefore, suggests the overall importance of enhancing different functionalities as well as services. Thus, you may have observed the rise and advent of new forms of technologies like location technology like GPS, and wireless communication technologies such as NFC for instance that ensures seamless wireless information transfer.
In this post, we discussed this technology in detail, citing the reasons for its growing popularity, followed by listing the ways the technology operates, and its salient features. Once you have gotten knowledge of this, we will discuss the techniques that businesses can follow during the development of an NFC reader app that ensures maximum interactivity, and maximum customers in the long run.
So without further ado, let us start.
Have a look at this video below to get a basic idea of NFC technology also known as near-field communication technology.

By observing this video, you may have gotten a basic idea of the technology. In the lines below, however, to ensure this technology is easy to understand, here is its definition below.
NFC had its inception done way back in 2004. From that point onward, there has been no looking back for it. It focuses on ensuring seamless information exchange which is wireless. This transmission takes place over short distances, approximately 10 centimeters via a chip embedded within a device.
Having its derivation done from RFID, a wireless system consisting of two components, namely, the tag and reader; it helps users perform different tasks like-
Knowing now about this technology, let us now understand its operations in the lines below.
When transmitting data via NFC technology, two NFC-enabled devices, one for transmitting and the other for receiving are what you need first.
Say, for example, you want to transmit information between the NFC tag and the smartphone, this means the former acts as a passive device that can only perform data transmission. However, the latter is an active device capable of performing two tasks: one receives signals from the NFC tag, and the second; transfers data to other NFC-enabled smartphones.
This might make you think that the technology is similar to Bluetooth. However, this is far from right. The technology (NFC) neither requires one to pair devices, nor permission to transmit data. All they have to do is to place a tap on the transmitting device through an NFC-compatible smartphone. Next, it becomes easy to receive information or perform different tasks like receiving payments.
Knowing how technology functions, it is vital to note the different techniques for communication to transpire through it (NFC).
There are two ways communication happens with the technology (NFC).
Knowing the different modes through which communication with NFC takes place, let us delve deep into the salient features of this technology that has been responsible for its growing popularity.
NFC technology is based on the RFID technology at 13.56 MHz, having an operating distance that is typically up to 10 cm.
This is followed by the compatibility support it renders to contactless RFID technologies, alongside a data exchange rate that is around 848 kbit/s.
Finally, the technology operates in three modes, namely, P2P, card emulation, and reader/writer.
All these unique aspects have been responsible for the overriding popularity of this technology, thus leading to more and more businesses embracing NFC app development services.
We also ensured to not keep ourselves behind. Being a known mobile app development company, we are known for embracing the top technologies when building apps. Thus, we made sure to implement the NFC technology in our recently launched app, Plap.
With the aid of this technology, we have built this app to give professionals the flexibility to seamlessly network and connect with one another through a scan they perform within the app.
Look at this image below to take a peek at the app below.
Through this image, you can get insight into how the app allows easy connection between professionals through a simple scan.
In the lines below, we provide knowledge on the simple operations of this app.
Take a look at the video below to observe how our Plap app seamlessly operates allowing professionals to network and connect easily with one another.
Seeing this video, you can notice how the app allows easy networking simply through a scan they perform.
Therefore, it becomes crucial to embrace NFC app development to your business advantage now. This will help to streamline its success to the greatest extent.
There are three ways you can do this.
Have a look at this image below to look into them.
In the image above, you can observe the three ways to build an NFC-powered app. This includes reader, peer-to-peer, and card emulation.
Below however we will be discussing the steps that need to be followed for building an NFC reader app for the iOS and Android platforms.
Have a look at the image below to get an idea of what we are saying:

Have a look at the image representations below to see how the task is done on the Android platform.
In addition to the methods highlighted in the image above, others that get followed before embracing the testing stage are recording the data to the NFC tag, pursued by creating a message containing a link or a phone number. This includes creating a message that possesses the location coordinates, where it is vital to mention non-typical errors within the code to allow users to gain insight in case NFC may not be available.
With these steps followed, it is a cakewalk to develop the NFC Reader app for the Android platform.
Now let us get an idea of how to develop an NFC reader app for the iOS platform below.
Note: In case the app reads the tag without providing the key mentioned above and the string, the app will exit immediately.
This also includes placing a tap on the Scan button again to gain perception into additional tags if present.
Have a look at the image below to gain insight into this better.
This allows the app to use the data fruitfully or store messages, etc so users can view them (messages) later.
Take a peek at the image below to understand this step better.
See this image below to observe this step visually.
Once this happens, it so occurs that the reader session detects a tag called the readerSession (_:didDetectNDEFs:) delegate method. This allows the detection of more than one tag, followed by the app asking the user to remove the extra tag and restart the polling to scan to detect new tags.
However, when app confirmation takes place for one tag alone, the tag connection and verification happen to ensure the same is writable. This allows the app to write the NDEF message read earlier to the tag.
Following these steps, you can build an NFC reader app that ensures contactless data transmission so that better business processes become easy to achieve.
Channeling NFC app development has helped businesses ensure seamless contactless communication between gadgets. This ensures seamless data transfer for short-range wireless data. Enterprises are already flourishing courtesy of channeling the technology. Hence, it becomes vital for you as an entity to gain a competitive edge. Get an NFC app that ensures unique customer service and streamlines business processes. This will keep you ahead in the market!
