How It Works

More than a wristband — it’s your vibe in motion.

sei-u lets you turn a simple festival moment into something unforgettable. Whether you’re sharing a playlist, a secret smile, or your rave alter-ego... it all starts with one tap.

 

1️⃣ What’s Inside: The NFC Chip


Each wristband contains a tiny NFC (Near Field Communication) chip that can wirelessly transmit data when tapped by a smartphone. Just tap and share. Whether it's your IG, SoundCloud, or a fire playlist, it's all one tap away.

 

2️⃣ How to Program Your Wristband

Set up your or update your URL link in 1 minute using the free NFC Tools app

(iOS / Android).

Steps:

1.Download the NFC Tools app on your smartphone.

2. Open the app and tap “Write”.

3.Choose “Add a Record” → Select “URL/Link”.

4.Paste your link (e.g. IG profile, Spotify playlist, etc.).

5.Tap “Write” and hold your phone near the wristband—done!

6.Test it by tapping the band with any phone (NFC-enabled).

🦉If your wristband contains more than one record, only the first valid URL will be triggered when scanned. To avoid issues, write only one URL per wristband.
🦉sei-u wristbands are designed to work best with the URL/Link format.
Using other NFC write modes (like text, app triggers, Bluetooth, etc.) may lead to inconsistent results or device incompatibility. We recommend using URL only — it's the most reliable, cross-device-friendly, and scan-ready format.
