Pairing your audio devices with your smartphone just got a whole lot easier with NFC technology.

Most smartphone accessory makers are now using NFC chips to help you pair your headphones or speakers with just a tap.

You can tap your smartphone in the right spot to start the pairing process.

This doesn't actually connect your smartphone to your headphones or speakers using NFC, as it has neither the range nor the bandwidth to handle an audio stream.

Instead, NFC is used to speed up the normal Bluetooth pairing process.

Once paired, your smartphone communicates with your accessory over Bluetooth in the same way as if you'd paired it manually.

You can also use NFC to pair up Wi-Fi speakers or other devices, like smart home accessories.

In these cases, NFC is used to exchange the necessary information to join your wireless network.

Bluetooth is commonly used for connecting headphones and speakers to smartphones, and it also supports wireless keyboards and mice on laptops and PCs. It provides significantly more bandwidth than NFC at ranges that are measured in feet rather than inches.

Bluetooth audio typically works at distances of 10–30 feet, while Bluetooth Low-Energy (BLE) devices can communicate at distances of 100 feet or more. This makes it a reliable choice for everyday use.

RFID is a precursor to NFC and is still used in security cards and key fobs due to its lower cost. It's also commonly employed in warehouses for inventory management.

RFID only supports one-way communication — from the tag to the reader — and can’t store nearly as much information. This limits its use to specific applications.

UWB is a new technology that promises to offer an alternative to NFC without requiring close contact. It's being used in tracking tags and digital car keys.

With Apple's AirTags, UWB can help you figure out which couch cushion your keys are hidden under. This is a convenient feature that's making waves in the tech world.

Android Beam is no more, having been replaced by Nearby Share, which is now rebranded as Quick Share.

It died with the release of Android 10, marking the end of an era where NFC was used to transfer files between devices.

Quick Share starts the connection using your location and Bluetooth, then picks between Bluetooth or Wi-Fi Direct to share the file, depending on what you're sharing.

NFC is no longer part of the equation, so you can't officially use it to share files, photos, content, apps, and other files.

There was something magical about tapping phones to transfer files, but unfortunately, that's a thing of the past.
