  1. Install NFC Tools (free).
  2. Open Write → Add a record → URL/URI.
  3. Paste your link (example): https://hydra-tag.com/log?uid={UID}&ml=250
  4. Tap Write, then hold phone to the sticker.
  5. Done. Test by tapping the sticker.

iPhone — NFC Tools

  1. Install NFC Tools (iOS 13+).
  2. Go to Write → Add a record → URL/URI.
  3. Paste your link (example): https://hydra-tag.com/log?uid={UID}&ml=250
  4. Tap Write and place the top of the iPhone near the sticker.
  5. Test by tapping — it should open your logging page.

Tip: Replace {UID} with your tag's unique ID if your system uses it, and adjust ml= to your usual sip size.
