NFC Android

NFC technology has multiple applications on Android.

What is NFC

NFC - acronym for Near Field Communication - is a technology of short-range, high-frequency wireless communication that allows information to be transmitted between two devices that have a chip of this type. Although the truth is that this communication can work in two ways, depending on how the connected devices are.

  • Active NFC Connectivity: the two devices that are connected generate an electromagnetic field with their own energy sources to exchange information with each other.
  • Passive NFC Connectivity: only one of the two devices has a power source, so it generates its own electromagnetic field, which is used by the other device to exchange information

As you can imagine, NFC technology is present on other sites apart from smartphones. For example, it is the technology that allows us to use public transport with a transport card, and, in fact, this is a good example of passive NFC, since these cards do not have their own power supply, but they take advantage of the magnetic field of the NFC sensor of the subway winches.

The transmission speed of NFC, on the other hand, is not too fast, since it can only reach one 424 kbit / s transfer rate, so it is not intended to transmit large amounts of data, but rather to verification and identification processes. Although, as we will see later, we also have the ability to send files between devices.

Its strong point is that, unlike Bluetooth, it does not require any type of pairing, but is instantaneous thanks to fast communication speed. Of course, at the cost of its range, which can at most be 20 centimeters.

In short, NFC technology has reached mobile phones to facilitate tasks that we do on a day-to-day basis, such as paying for the purchase, transferring files or pairing the phone with Bluetooth accessories such as wireless headphones, and we will see it in the next section.

What is NFC for on Android

NFC is essential in current smartphones due to the wide number of functionalities it offers, which are detailed on the NFC Forum website. There are three main functions:

And based on these three uses we can take advantage of the NFC in many ways on our Android mobile, and we are going to tell you what they are. those that you can use on a day-to-day basis:

  • Mobile payments: Paying with your mobile is perhaps the use of NFC that we value the most, since, either through Google Pay or our bank's applications, we can pay with our smartphone as we do with a bank card. This allows us to be able to leave the credit card at home, and always be aware of unexpected expenses. In addition, most businesses today are compatible with this type of payment.
  • Quick pairing with Bluetooth devices: One of the things we've been seeing for years is that accessory manufacturers, like bluetooth headphones or speakers, add NFC to your devices, which we can pair quickly just by bringing them closer to our terminal. A process that saves us time and makes it very easy to use any of these Bluetooth devices.
  • File transfer between mobiles: Another use of NFC is the transfer of files between two mobiles that are together. You just have to activate the NFC, open the file you want to share, join the two phones and accept the file transfer to send or receive the information.
  • Wireless charging accessories: As reported by the NFC Forum, one of the most unknown uses of NFC is the wireless charging of small technological devices after the approval of the Wireless Charging Specification (WLC) standard. For example, you can charge bluetooth headphones or smartwatches.
  • Personal identification: With the NFC you can use your mobile also as an identification tool when use public transport, open the front door, do "check-in" at a hotel, open the car door, or to enter concerts or museums.
  • NFC tags with automated actions: NFC tags are small devices with passive NFC that we can program so that, when they come into contact with our mobile, they perform all kinds of functions automatically, such as turn on bluetooth or even activate airplane mode. You can also use these labels find in a museum to receive additional information on his paintings, in a store to access special offers or at the taxi rank to initiate a call with a taxi driver.
