The NFC is a technology that takes several years with us. Despite this, there are multiple uses of it that today can be unknown since it seems that we only talk about mobile payments when we refer to this small chip that many of the current phones carry.

We are going to tell you what are the uses that NFC can have on our mobile so that you know the potential of NFC that can be used for various options that you may not yet have present.

Transfer photos, video or music

Although the use of NFC in Android to transfer files is not very widespread, it is possible to carry out this type of transfer with compatible devices. Currently, there are some cameras and laptops that have NFC included, so we can share the files directly from the mobile phone . This saves us having to be connecting by cable or using Bluetooth.

Technically the transfer is done by Bluetooth or WiFi Direct, but the NFC eliminates the pairing to make everything faster and easier for the user.

Use the mobile key for the car

Using the smartphone as a car key is not a standard, but the technology already exists and it is more than likely that the future will become more and more common. The NFC can be integrated into a vehicle so that, when it comes into contact with our phone, the vehicle can be opened as if it were a key to use.

Apple, Audi, BMW, General Motors, Hyundai, LG Electronics, Panasonic, Samsung, Volkswagen, Alps Electric, Continental Automotive, DENSO, and Qualcomm are among the major companies working on this technology, demonstrating the potential impact it could have on our lives in the future.

To identify you at the cashier

You may not know it but you do not need to use the card to identify yourself at the cashier . It is enough to have the mobile phone unlocked for it to read our NFC chip (in the case of having the mobile configured for this) and the ATM recognizes our card.

Personally, this is an option that I always use, since it avoids having to remove cards from the wallet. You take out your mobile, put it on top of the ATM’s wireless reader and voila, you can now operate as normal.

Mobile payments

And continuing with the banking issue, it was mandatory to talk about mobile payments. The main advantage here is that we can carry several cards stored on the mobile, so we do not have to go looking in the wallet for the one we want to use depending on the circumstance.

Applications like Google Pay and Samsung Pay allow us to keep and configure many cards so that we may choose which one to use from the phone itself. It is a fairly quick way to pay, as long as the POS accepts wireless payments, which is now very common.

Personal identification

Currently, it is not a very widespread practice, but the NFC of our mobile can serve as a personal identifier. For example, at the Mobile World Congress itself, the NFC Badge was implemented, accreditations through NFC that allowed access to the venue through this identifier. This method is applicable to workplaces, festivals, travel passes, and so on.

Device Synchronization

Although Bluetooth is still the king when it comes to connecting to devices, NFC is not far behind in connection speed and stability. Through this technology we can connect the mobile to headphones and speakers quite quickly, without having to go through the Bluetooth connection process which, depending on the device, can become somewhat tedious.

Automation of actions

NFC tags have existed for years and allow us to automate actions for when our phone detects them . For example, we can automate the connection to WiFi when we enter the house, activate music playback, configure alerts and more.

Share the WiFi key

Sharing WiFi when friends or family come home can be a hassle. Using an NFC tag and an application like Trigger to configure its functions, we can make the NFC tag an activator of said key. In this way, we can share the data of our network in a simple way.

Access public content

Linked to the automation of tasks, it is good to dedicate a few words to how the NFC can be put at the free service of citizens. For example, in the city of Granada, a combined system of QR and NFC codes was implemented in the Alhambra. By bringing the mobile closer to a surface we can access different guides, a quite comfortable way to have it at hand through the smartphone.
