How to Program NFC Tags

how to program nfc tags

If you just bought an NFC tag, you might be wondering how to program it. Luckily, programming NFC tags is easy. Here, we show you how to program NFC tags using Android and iPhone devices.

NFC Definition

NFC, or Near Field Communication, is a technology that allows devices to communicate with each other when they are close together. Note that the devices must be approximately 4 inches from each other.

The communication depends on NFC tags. These are small stickers that can be programmed with information such as a website address, phone number, or contact information. 

An NFC device can either act as a tag or a reader. A tag is a device that stores information, and a reader is a device that can retrieve information from tags. For example, if you want to send a file to someone, your phone will be the tag, and the recipient’s phone will be the reader. 

Besides sharing information/files, you can use NFC tags for other smart applications, including:

  • Automatically open a web page when you walk into a store
  • Logging into your Wi-Fi network
  • Triggering an action on your phone, such as turning on the flashlight or playing music
  • Starting your car

These are just a few examples of what you can do with NFC tags. Otherwise, its applications are limitless.

Programming NFC Tags with Android

To program an NFC tag with Android, you will need the following:

  • NFC Writer App. This app is available for free on the Google Play Store.
  • Blank NFC Tag. These are available for purchase on Amazon or at your local electronics store.

Once you have installed the NFC Writer app, you should follow the following steps:

  • Enable NFC. NFC settings are in the Settings Menu. If you cannot find NFC, check under “More Wireless & Networks” or “Security & Location.” Once you find NFC, you should check the box next to it. 
  • Open NFC Writer by Trigger App. After installing this app, you should open it. Select the add action icon in the top right corner of the app. You should then choose NFC as the location of the action.
  • Add Restrictions. To add restrictions, select the “Add Restrictions” option. You will then be prompted to enter a password. This password will be required to access the information stored on the tag. 
  • Enter Information into NFC Writer App. The next step is to enter the information that you want to store on the tag. This includes the website address, contact information, or any other type of information that you want to share. You can also choose from pre-existing actions. For example, if you toggle the BlueTooth action on, the Bluetooth will be activated every time you read the tag.
  • Click Done and Save. This option is at the bottom of the screen and allows you to save the information you have just entered. 

You can always edit this information when you need to update your commands.
