Introduction

NFC (Near Field Communication) tags are a powerful and inexpensive technology that you can use to automate various tasks in your smart home. These small and inexpensive tags pack a powerful punch when it comes to automating your smart home. However, despite their affordability, they are often underutilized in smart home automation causing many homeowners to miss out on their potential as a powerful automation device. With a little imagination, you can use NFC tags in a variety of ways in your smart home, from turning lights on and off, to adjusting the temperature, to controlling appliances. And as a practical matter, in some situations, you can even use them to  replace your more expensive smart switches, smart buttons, or remote controls.

Before delving into the programming aspect of NFC tags, it’s worth highlighting five key reasons why they’re considered a “hidden gem” in smart home automation. These reasons include:

Small Profile

One of the best things about NFC tags is their simplicity. They are small, unobtrusive, and can be placed just about anywhere. They can be as small as a coin or even smaller, making them ideal for automating devices in tight spaces or hard-to-reach locations. You can easily affix them to a wide range of surfaces using adhesive or a small clip. But don’t judge the book by its cover – their small size belies their powerful functionality. With just a tap, you can program them to trigger a variety of automations that can make your life easier and more convenient.

Waterproof Technology

In addition to their size and cost advantages, NFC tags have another advantage over smart switches, buttons, or remote controls that makes them excellent for smart home automation: they are waterproof. This capability makes them a reliable choice for automating devices in any area of your home, including the kitchen, bathrooms, and outdoor spaces.

Secure Technology

Moreover, NFC tags offer a level of security that is difficult to match by other technologies. They use secure communication protocols, such as NDEF (NFC Data Exchange Format) and SNEP (Simple NDEF Exchange Protocol), to ensure that data is transferred securely with the scanning device and cannot be intercepted by unauthorized parties. The tags themselves also have very limited storage capacity, typically only enough for a small amount of data such as a URL or ID number, which makes it difficult for bad actors to access sensitive information. Additionally, NFC tags can be password-protected or encrypted to add an additional layer of security, and have a very limited range, typically only a few centimeters, which makes it difficult for anyone to scan the tag remotely and reduces the chances of unauthorized access.

Reprogrammable

Another advantage of NFC tags is that they can be reused and reprogrammed. With this capability, you can change their functionality on the fly to perform different tasks. Meaning that you can easily change the automation associated with a specific tag without having to replace it. Additionally, you can program NFC tags with various types of data, including text, URLs, and even small programs, making them a versatile tool to power many home automation projects.

Energy Efficient

Finally, NFC tags are energy-efficient and do not require batteries or any source of power to operate. Instead, they are powered directly by the magnetic field of the NFC sensor of the mobile phone or the device that reads them, which means that they can last for an extended period of time without any maintenance.

NFC Automation Ideas

Now that you understand why NFC tags are so powerful, let’s explore 16 unique ways in which you can utilize the power of NFC tags to automate various tasks in your smart home:
