The Ultraloq Bolt NFC smart lock is receiving a free upgrade that enables near-field communication (NFC) tap-to-unlock with compatible Android phones. The model currently supports Apple’s Home Key, which lets you tap-to-unlock with an iPhone. The update makes it one of the first locks to offer the functionality across both iOS and Android, without requiring the phone to be unlocked or specific apps to be running.
The ability comes via a free software upgrade to the U Home app, available now in the Google Play Store. Xthings, Ultraloq’s parent company, says its NFC unlock experience is an app-managed credential system, relying on Android’s NFC default app handling. This allows tap-to-unlock to work with an “out of the pocket” experience; no app needs to be open, no screen activated, no unlocking required, “just a simple tap.” The company states that it will support an estimated 99 percent of NFC-enabled Android smartphones currently on the market.
According to Xthings, its NFC unlocking on Android works by setting the U Home app as the phone’s NFC handler, allowing it to “run as a lightweight background service to listen for NFC intents.” When you tap the phone against the lock, it triggers the Android system to wake the correct NFC handler and pass it to U Home for authentication.
NFC unlocking requires both the phone and lock to support NFC, allowing you to tap to unlock in the same way you tap to pay. It’s a common feature on some smart locks for iPhone users, but Android phones have not had as many options, often requiring the use of a tag or key fob. An upcoming smart lock standard called Aliro aims to make NFC unlocking universal, regardless of phone manufacturer, but it hasn’t launched yet.
