From telegraphs to online video calls and from fax machines to emails, the communication means have evolved exceptionally. Now the world has shifted from wired networks to wireless transmission, the internet being the most significant model.
Now people do not want to wait for replies, messages are sent and received in milliseconds. Modern messaging apps are an example of it. Transferring large files was a problem for businesses in the past, it can take hours to load. Currently, centralized cloud storage is giving easy access to data anywhere in no time.
According to some experts, wireless is not a secure way of communication because it can be hacked. If this is true then why people are still using wireless (Wi-Fi) in their daily routine. The reason is, communication providing services have secured it at the highest level with minimum chances of phreaking.
Now people are using credit cards for in-store and online payments. To protect this type of sensitive communication, there is a need for a secure and quick communication mode. At this level near field communication (NFC) can completely comply with the high security and speed demands.
Understanding NFC Technology a Bit Better
Near field communication (NFC) is a limited-range contactless technology that uses radiofrequency waves for signal transmission. Simply NFC is a subset of radio-frequency identification (RFID) with the two-way transmission. Two NFC-enabled devices can send and receive data when in a nearby presence.
Types of NFC Operations
NFC devices are divided into four types based on their operation modes.
Reader-Writer
NFC devices can receive and transmit data from NFC chips. Extracting information from a smart poster or opening a particular website, for example.
Peer-to-Peer (P2P)
Two NFC-enabled gadgets as mobile phones can interchange data through a single tap. Sharing Bluetooth, Wi-Fi or interchanging information with virtual business cards.
Card Emulation
This mode is used for payments in POS systems, where an NFC device works as an external scanner. Mobile phones act as smart cards through which data is sent and received.
Wireless Charging
This is the most advanced mode of NFC used for charging small IOT devices like Bluetooth or smartwatches. It allows wireless charging of up to 1-watt power.
What to Expect from NFC in Future
The card payment sector initiates NFC named as NFC payment verification and now other industries are also using it. The market size of NFC-related technologies is forecasted to reach US 34.9 billion by 2025, with a growth rate of 14.2 %. About all advanced mobile phones have NFC readers in them. It is predicted that card payment will be succeeded by smartphones in the coming years.
As NFC technology (chips and readers) are becoming common, it can be incorporated for other operations also. Many governments are integrating NFC chips in id cards and passports. The document verification can be performed in a better way because NFC chips can’t be copied. Less physical space and large data holding capability with solid security can replace QR codes.
Final Thoughts
NFC identity verification can be used to verify the identities of individuals by extracting information through their documents. Businesses that are in search of reliable and secure verification methods should choose NFC identification solutions. This will safeguard their channels while giving the best customer service.
