Near Field Technology (NFC) is a wireless communication technology that enables users to share data between two NFC-enabled electronic devices.
The technology uses NFC tags with enough memory to store data. However, this data sharing technique is only practical if the two devices are at most 4 inches away from each other.
This article enumerates the ten coolest NFC tags uses that will transform your life for the better. It also offers a comprehensive guide on the usage of NFC tags Android and NFC tags iPhone. Read on.
What is NFC Tag?
The idea that you could make contactless payments for your shopping bills may have seemed like far-fetched fiction, but it is now a reality.
Yes! NFC tags have made it possible to shop for groceries, pay for your fuel, and pay any other bill by merely taking your card near an NFC reader stationed at the shopping stores.
But how exactly does NFC tag technology work?
Well, an NFC tag refers to a chip that can store data. It integrates an antenna that helps in radio wave transmissions. You can add the small NFC tag to materials such as credit/debit cards, wristbands, and key fobs.
Whenever the tag is near an NFC reader, it detects the reader’s waves and sends the data through the antenna. Once the reader receives the data, it sends it to the NFC software for analysis.
If the data is authenticated, then the reader will subtract the bill from the card’s balance. This process takes a few seconds to complete. You can use it for access management, event management, and many other activities that need prompt identification.
RFID vs. NFC: What’s the Difference?
While there are a few differences between RFID and NFC, both use radio waves to send and receive information. Here is a breakdown of the two closely related technologies:
RFID vs. NFC: Definitions
Radio Frequency Identification (RFID) is a wireless data transfer technology. It uses radio waves to exchange data, and it is useful in identifying and tracking valuable commodities. It has RFID tags that store encoded data.
NFC refers to a short-range wireless technology, primarily used in electronic devices and smartphones to share information. It enables two devices to establish communication with each other.
RFID Tags vs. NFC Tags: What’s the Difference?
NFC tags use a similar concept as Radio Frequency Identification (RFID) tags. When you have them, you can exchange data between devices. However, RFID tags use different frequencies ranging from 125 kHz to more than 900 MHz.
On the contrary, NFC tags use a standard frequency of 13.56 MHz, similar to a high-frequency RFID tag. Additionally, NFC is standardized by ISO/IEC 18092 to ensure that it meets the safety requirements, thus safeguarding the users.
Also, NFC devices can act as both the reader and the tag. When sharing data, the recipient device becomes the reader, while the sender is the tag that stores/transfers the data. On the other hand, RFID tags only store information, making it mandatory to have an RFID reader for the system to work optimally.
12 Creative Ways to Use NFC Tags
1.NFC Tags for Contactless Payment/ Card Emulation
This is, without a doubt, the most revolutionary NFC tags’ application. You no longer need to carry your wallet/purse to pay your bills!
