How NFC tags protect your belongings (without exposing your data)

A lot of people ask the same question: "if I stick a tag on my backpack, can someone use it to find me?". Short answer: with GoTaggle, no.

What NFC actually is

NFC (Near Field Communication) is a passive chip that wakes up when a phone is within 2-3 centimeters. It has no battery, broadcasts no signal on its own, doesn't track. It only responds when asked.

When someone taps their phone on your GoTaggle tag, the chip hands over a public URL — something like gotaggle.com/t/abc123 — that opens our recovery page. That's it.

What the scanner sees

The page depends on the state you left your object in:

• Active & normal: just the object's name and a way to report it if it's lost.
• Marked as lost: the instructions you wrote plus an option to message the owner anonymously.
• Reward set: the amount and how to claim it.

The person scanning never sees your real name, phone, or address. The conversation routes through an anonymous channel inside GoTaggle.

Proof of ownership

For objects with real value history (laptop, instrument, travel backpack), GoTaggle records every activation and transfer in a hash-chained history that can't be rewritten, and you can add private questions only you can answer. That's how you prove ownership without an invoice or receipt. Coming soon: premium NTAG 424 DNA tags that sign every read to detect cloned chips.

In short

NFC lets you give every physical object a digital identity, separate from your personal identity, that you control and can switch off anytime.
