An NFC (Near Field Communication) tag is a small chip that stores data and shares it wirelessly when you tap it with a phone or NFC reader.

If you have ever tapped your phone to pay, you have used the same underlying tech. An NFC tag is the thing you tap that contains a little bit of information, like an ID number, a web link, or instructions an app can read.

A simple way to think about it: an NFC tag is like a sticky note for your phone. It is small, it does not need a battery, and it only matters when you read it.

Most NFC tags work the same way. They are usually passive, meaning they do not transmit anything until a phone is placed very close (typically a few centimeters). When you tap, your phone powers the tag for a moment, reads the data, and your app decides what to do next.

NFC tags are used across many industries:

• Payments and banking: tap-to-pay, card provisioning, and secure access
• Retail and consumer products: smart packaging, product info, and authenticity checks
• Transit and events: ticketing, passes, and fast check-in
• Security and access control: door badges and device pairing

Why this matters for your security

NFC is useful in hardware wallets because it can make secure actions feel simple. A tap is an intentional physical step, which helps reduce mistakes like approving something you did not mean to.

In self-custody, the safest workflows are often the ones you will actually follow. NFC can remove friction without removing control.
