      Smart Strap FAQ's

      • Is my profile data secure?

        Lifekey® is based on blockchain technology and uses private and public "keys" to manage access to data. Your private key (unique ID) is stored in the cloud and is encrypted both in transit and at rest. Your devices also use unique keys for identification. Lifekey technology is also developed to be HIPAA compliant.

        Will it work without cell service?

        The consumer version of Lifekey requires an internet connection to send/receive information. Data is encrypted and stored in the cloud.

        Is it waterproof?

        Yes, all Lifekey® devices are designed and built to withstand outdoor pursuits, as well as daily uses.

      • Is there a warranty?

        You bet! Check out our support page for details on our Anytime, one time warranty!

        Does someone need the app to scan my smart strap?

        There is no app needed to scan and access a Lifekey. Older iPhones (from 2016 and prior) may require an app to scan. iPhone 7 is the first iPhone with NFC capability.

        An app is required to setup your own device or a device you manage.

        Is my phone compatible?

        iOS 11 and iPhone 7 and up are compatible with Lifekey. iPhone 7 was the first iPhone that had the capability to read NFC outside of Apple Pay.

        Lifekey®will work with most Android phones. However, there are a few exceptions that include less popular phones. See this list.

      • Is this a tracking device?

        Lifekey® wearables use passive NFC technology. The wearable generates power to transmit data only when in contact with a smartphone (at approx 1 cm or less). So, devices can't be tracked and data cannot be accessed from a distance without your approval. You can also easily disable any of your wearable devices from the Lifekey® app.

        Does it need to be charged?

        Nope. Lifekey® harnesses its energy from a smartphone when it is tapped. You'll never have to replace batteries or recharge!

        Are there any health risks?

        Lifekey® devices with NFC technology use the low-end of the electromagnetic spectrum. The waves coming from readers are no more dangerous than the waves coming to your car radio.
