A near field communication tag (NFC tag) is a sticker/wristband/card/plastic disc with an embedded microchip that can be read by in range mobile devices. Information is stored in these microchips. A NFC tag becomes energised when a compatible NFC reader in a mobile phone is bought into proximity (usually 5cm or less) and then has the ability to send data to that mobile phone.

What is NFC?

A selection of different NFC tags

A Near Field Communication (NFC) tag is a small, passive device—such as a sticker, wristband, card, or plastic disc—that contains an embedded microchip. These tags can store data and are powered when a compatible NFC-enabled mobile device comes within range, usually 5 cm or less. Once activated, the tag can transmit its stored information to the mobile device.

How Can They Be Used in Geocaching?

NFC tags offer innovative ways to enhance geocaching experiences:

  • High-Tech Waypoints: Some NFC tags are waterproof and durable, making them suitable for outdoor use. They can serve as modern waypoints in multi-stage or puzzle caches.
  • Interactive Challenges: Encode clues, coordinates, or puzzle solutions on the tags, allowing geocachers to interact with the environment in new ways.
  • Creative Deployments: The applications are limited only by imagination—consider embedding NFC tags in unique locations to create memorable geocaching experiences.

Where Can I Get One?

NFC tags are widely available and can be purchased online at affordable prices. Ensure you select tags that are compatible with your intended use, such as waterproof tags for outdoor caches.

How Do I Program It?

Programming an NFC tag is straightforward and can be done using your smartphone:

  1. Download an NFC Writing App: Install an app like NFC Tools (available on both Android and iOS).
  1. Open the App and Select 'Write: Launch the app and tap on the 'Write' option to begin the programming process.
  1. Add a Record: Tap 'Add a Record' and choose the type of data you wish to encode, such as a URL, text, or coordinates.
  1. Enter the Data: Input the desired information. For example, to redirect someone to a webpage, select 'URL/URI' and enter the URL.
  1. Write to the Tag: After reviewing the data, tap 'Write'. Hold your smartphone near the NFC tag until the app confirms the writing process is complete.

Now What?

Once programmed, place the NFC tag at your desired location. When another geocacher scans the tag with their NFC-enabled device, they will receive the encoded information, such as a link to a webpage or coordinates for the next stage of the cache.

Are There Any Limitations?

To ensure smooth interaction with NFC tags, be aware of the following limitations:

  • Device Compatibility: Your smartphone must have NFC capabilities and have NFC enabled in the settings.
  • Battery and Mode: Scanning may not work if your phone's battery is low or if it's in Airplane Mode.
  • App Interference: Certain apps, like digital wallets (e.g., Apple Wallet), may interfere with NFC functionality.
  • Device State: Scanning might not work if your phone's camera is in use or if the device is locked.
