NFC technology is included in all modern cellphones. Your phone is probably utilizing NFC right now, whether you recognize it or not. But don’t panic; NFC consumes very little battery and processing power while providing a slew of benefits that boost the functioning of your gadget.
Despite its widespread usage in peer-to-peer payment and data-transfer apps, NFC offers a plethora of other uses that might simplify your life. Continue reading to learn how to fully utilise your phone’s NFC potential.
What exactly is NFC on my phone?
Near-field communication (NFC) allows phones, tablets, laptops, and other devices to quickly communicate data with other NFC-equipped devices. It arose as a result of radio-frequency identification (RFID) technology. RFID is the technology underlying the security scan cards that allow you to enter the office every day or avoid the tollbooth on your morning commute.
NFC is similar to RFID in many ways, but it is limited to communication within 4 inches, so you must keep your phone close to the contactless scanner if you use Apple Pay or Samsung Pay. Most people regard NFC’s limited radius as a significant security benefit, which is why NFC has gained popularity as a safe alternative to credit cards.
Bluetooth vs. NFC technology
NFC is quicker, safer, and more dependable. I could go into great length on the super-secure military-grade encryption, That two NFC devices can connect in under 0.5 seconds, or that NFC Technology is particularly built for data transfer between two devices near one other, making it the most secure means to send data between devices.
Let’s look at a real-world case. When you return on the bus after a hard day at work, you put on your Bluetooth headphones and switch on your smartphone’s music, but nothing comes through. You turn up the volume, expecting something to happen.
How does NFC function?
Like Bluetooth, NFC transfers data without requiring manual pairing or device discovery. When another NFC device reaches the previously selected 4-inch range, an NFC connection is instantly established. When the two gadgets come into contact, they instantaneously interact and provide prompts to the user. The following are some of the most common ways we now use NFC across devices.
Payments using a mobile device.
Mobile payments are becoming increasingly popular as we move toward a cashless society. Making a mobile payment is secure and simple because to bank collaboration and biometric technology incorporated into most recent devices. When you place your smartphone within 4 inches of a contactless reader in a store, your digital wallet or passbook will appear and ask you to confirm payment. This is done with Apple Pay by placing your finger on the Home button, which contains the Touch ID feature, or by double-pressing the Power button to scan your face with Face ID. It is also compatible with Google Pay and Samsung Pay.
Passive tags do not require electricity and may be configured to do certain actions when scanned using programs such as Tasker. Put one on your desk, for example, and with a simple scan of the tag, you may set your phone to vibrate, deactivate GPS, or enable just work-related alerts, among other possibilities. Passive tags do not communicate with other passive devices or analyze data from other sources. Active NFC devices, such as smartphones, may transmit and receive data and converse with both active and passive devices.
What more is NFC capable of?
NFC can do so many tap-and-go operations that digital wallets like Apple Pay, Google Pay, and Samsung Pay only cover a small portion of its potential. Music enthusiasts may rapidly connect their mobile to speakers through NFC, and you can also log in to your work computer, open your car door, or check your health and fitness metrics with a touch on your phone.
This technology is transforming public transportation; for example, you can scan an NFC-enabled smartphone on some buses or use it as a metro pass in some cities. You may add money to a bus or metro pass straight through an app, guaranteeing that funds are always available on your card. This system can handle loyalty cards as well as student IDs. Finally, the option of implanting an NFC chip into your body.
NFC tags may be used for several purposes. Consider making NFC coasters to provide visitors access to your house Wi-Fi as a way to learn more about this technology.
