  • The tag's unique identifier (UID)
  • Timestamp of the scan
  • Your approximate GPS location (if location permissions are granted)

This data is used to verify your visit, prevent fraud, and award the correct number of EcoDrops. For full details, see our Privacy Policy.

10.3 Usage rules

  • You must be physically present at the location to scan a tag
  • Cooldown periods may apply between consecutive scans at the same location
  • GPS spoofing, tag cloning, or automated scanning is strictly prohibited
  • Tampering with, moving, or damaging physical tags is prohibited

10.4 NFC compatibility

NFC scanning requires a compatible device and browser (currently Chrome on Android). QR code scanning is available on all devices with a camera. We make no guarantee that NFC scanning will work on all devices.

For complete rules about scanning, fraud prevention, and tag usage, see our Acceptable Use Policy.
