The NFC chip in mobile phones is often overlooked, but it can be a powerful tool for improving efficiency and streamlining tasks. In addition to mobile phone payments, the chip can be used for a variety of other functions, such as quickly connecting to other devices or sharing information.
To get the most out of your mobile phone NFC, it’s important to understand how to properly activate and use the chip. Before diving into the various ways you can use mobile phone NFC, make sure that it’s activated and ready to go on your device.
Configure NFC on Android
One of the most important aspects of using mobile phone NFC is ensuring that the chip is properly connected and configured. To do this, you’ll need to go into the settings of your mobile phone and follow these steps:
- Go to ‘Connected devices’ and check which devices are currently connected to your phone.
- From there, go to ‘Connection preferences’ and select the ‘NFC’ menu.
- Check to see if the NFC feature is activated on your phone. If not, turn it on.
Another useful option you may find in Android devices is the ability to choose which app you use for contactless payments. To do this, simply follow the above steps and in the ‘NFC’ menu, select ‘Contactless payments.’ This will allow you to change the default payment app to one of your choice if you prefer.
Configure NFC on iPhone
Unlike Android, the iOS operating system does not provide many options for checking if the NFC chip on an iPhone is activated, functioning properly, or if it has any issues. One of the only ways to configure the NFC chip on an iPhone is by using it for contactless payments.
This is because Apple controls the use of the NFC chip, ensuring that it is always activated when needed and deactivated when not in use. All you need for this feature to be enabled on your iPhone is a device model 6 or later, and the specific app you want to use for payments.
One of the key advantages of using NFC technology is the ability to easily share a variety of items with others. With NFC, you can share files and even the password for your WiFi network, providing a convenient and efficient way to transfer information.
Whether it is to share Contact, Photo, Music, File, WiFi password, or web URL, NFC makes it easy to share with people nearby, which can be very useful in many situations.
Sharing files is a common task that we perform regularly, but using NFC technology to do so is not as widely used. On Android devices, however, it is relatively simple to share files using NFC.
Here’s how you can do it:
- With NFC activated and the ability to share turned on, open the file you want to share.
- Bring the back of your phone in close proximity to the other device.
- You will feel a vibration and a small sound, indicating that the file is ready to be transferred.
It’s important to keep in mind that this process may vary depending on your mobile phone and its model, as not all devices fully support NFC technology. In addition, for compatible devices, you can also share files using NFC between computers, cameras and other devices.
As for iOS devices, the limitations of NFC are well known, and therefore other options such as AirDrop tool can be used to share files, although it doesn’t use NFC but it serves a similar function.
Sharing WiFi Password
Sharing a WiFi password, especially when it’s long and complex, can be a tedious process. However, NFC technology can make it easier and more efficient by allowing you to share the password with others quickly.
On an iPhone, if someone is nearby and trying to connect to a WiFi network that you are connected to or have access to, it can be done automatically. The other person simply needs to select the network they want to connect to, and a message will appear on your phone asking if you want to share the password.
On Android, there are other technologies like Nearby Share that can be used to share WiFi passwords. Additionally, you could use an NFC card together with the mobile phone or the router for password sharing. But keep in mind that availability will depend on the device and the version of Android.
Other NFC Tricks
NFC technology offers a wide range of possibilities and versatility for our mobile phones, and there are other uses and tricks that can be applied beyond the phone itself. NFC can interact with various elements in the surroundings to perform different types of actions. Such as opening car doors, withdraw money from the ATM, activating car engine and so on.
Open Car Doors with your mobile phone
Opening your car doors with your mobile phone is a feature that is not yet widely available and may not be compatible with all cars. However, some car manufacturers are making progress in this area and are working with mobile phone brands like Apple to make it more widely available.
For example, with the latest version of Android 12, some BMW models as well as gears such as Audi, Hyundai, or Mercedes-Benz have enabled this feature. It’s best to check with your car dealer to see if your car is compatible and to know how to activate this feature, if available.
It’s worth noting that this feature is just as secure and reliable as using your car key, so you can be assured that there is no added risk. With NFC it’s easy to open your car without any key, just bring your phone near to the door handle and it will open.
Withdraw money from the ATM by NFC
The use of NFC technology on mobile phones can make banking tasks more convenient and efficient. One such task is withdrawing money from an ATM. Instead of using a credit or debit card, you can use your mobile phone and its NFC chip to identify yourself and access your bank account at the ATM.
To do this, simply activate the mobile phone payment platform on your phone, such as Google Pay or Apple Pay, and select the bank card you want to use. Bring your mobile phone close to the contactless system of the ATM. If the ATM has the contactless feature, it will give you access to the same options you have when using your physical debit or credit card.
It’s important to remember that this feature will depend on the ATM and not all ATM are contactless enabled, it’s better to check with your bank or the provider of the ATM itself.
