Tapster Share – Share Information Easily The wristband also comes with Tapster Share—a smart NFC accessory that lets you quickly and easily share important information, without needing a battery or an internet connection. You can enter contact information, any allergies, the address of a meeting place, or other details that might be valuable. Perfect for outings, travel, or other situations where safety and accessibility are especially important. *Note: The bracelet is water resistant, not entirely water proof. We do therefore not recommend to swim or shower with it.
