Introduction
NFC stands for Near Field Communication. It is the technology that allows wireless communication for the Cayman Islands Identification cards. You have probably used NFC before, whether you know it or not. It is commonly used in credit and debit cards for tap to pay features, key FOBs for entering secure areas, and wireless smartphone payment.
How does it work?
NFC is a complicated technology that uses magnetic fields to transmit power between devices. This allows your smartphone or card reader to power an ID card without physical contact or wires. This connection is slow, but reliable, and has a very limited connection range (often no more than a few centimeters), which keeps it secure.
Does my phone support NFC?
Most phones from the last several years have NFC. It has become a standard feature found on all but the lowest end phones. All iPhones since the iPhone 6 have NFC, and most mid to high end Androids since 2014 have NFC. Sometimes, NFC compatibility may also depend on your region, as some manufacturers may omit the feature depending on regional adoption rates.
If you have an iPhone 6 or newer, it supports NFC.
It is not as simple to know on Android. Most Android phone manufacturers customize Android slightly, and as a result, some of the settings may have different names or be in different places. The best way to guarantee compatibility is to search the internet for the model of your phone.
To know if an Android phone has NFC, open your settings app and type "NFC" in the search bar. If your phone supports NFC, then you will be able to see the setting. If you cannot locate the setting, open “Connected devices” or “Connection Preferences” in settings. If NFC is not listed as an option, your phone does not support the technology.
NFC is not working
Sometimes, NFC is disabled by default, or may be behaving incorrectly. Check your device settings for NFC by typing “NFC” in the search bar of the settings app. Make sure NFC is enabled. If it is already enabled but not working properly, turn the NFC setting off and then on again. If NFC is still not working with a known working NFC device or card, restart your phone by performing a shut down, and then turn the phone back on.
To restart an iPhone, press and hold the volume down button and the power button until you have the option to power off. On Android, press and hold the power button until you have the option to restart or power off.
Once the phone has powered off, press and hold the power button until the phone turns back on.
