The Problem
Water is the enemy of electronics. Standard NFC tags can fail when exposed to moisture, rain, or washing, making them unsuitable for many applications.
Who This Is For
- Laundry and textile applications
- Pool, spa, and water park deployments
- Outdoor asset tracking in rainy conditions
- Medical and healthcare environments requiring sanitation

- Confusing water-resistant with waterproof
- Not checking adhesive is also waterproof
- Using standard tags and laminating them (air bubbles trap moisture)
- Ignoring water temperature (hot water is more damaging)
- Not testing wash cycle durability for laundry applications
Frequently Asked Questions
IP67 means the tag can withstand immersion in 1 meter of water for 30 minutes. The "6" indicates complete dust protection, and "7" indicates water immersion resistance.
