The world is changing rapidly. New and better technologies are emerging to ensure people find new ways to connect deeply. In a hyper-digital world, Bluetooth, RFID, and NFC have redefined the ways businesses operate. However, it’s hard to keep yourself updated in the digital world.
Do you have a lingering question like NFC vs. RFID vs. Bluetooth – which is better for your business? What exactly is the difference between these technologies and how do they function? Worry not, it’s time to take a closer look and understand the distinction between all of them.
Let’s begin by diving deep into the basics. We will also help you decide which technology will be the best fit for your business.
What is RFID?
RFID( Radio Frequency Identification) is a wireless technology that uses radio waves or electromagnetic fields to detect and monitor the movement of objects and people. The tag contains a unique identification code that stores all the information of an asset.
On the other hand, the reader sends and receives signals to/from these tags. RFID is widely used in inventory tracking, supply chain management, and access control.
What is NFC?
Near Field Communication is a subcategory of RFID. The main difference between RFID and NFC is the distance. The range of NFC is small usually within a few inches. The NFC protocol allows two-way communication between multiple devices making it suitable for online payments and access control.
What is Bluetooth?
Bluetooth is a wireless signal technology used for sharing data between devices over short distances. It is used in applications like smartphones, wireless headphones, speakers, and IoT devices. Almost all everyday gadgets have Bluetooth support to exchange data.
Now that the basics are clear, let’s move to the detailed comparison of NFC vs. RFID vs. Bluetooth.
Understanding NFC vs. RFID vs. Bluetooth
Technology keeps evolving and businesses need to reinvent themselves to survive in the fast-paced world. You may already be using one or two of these technologies but it’s crucial to dig deep into each of these connection systems to stay ahead of your competitors. Without further ado, let’s analyze NFC vs. RFID vs. Bluetooth.
