The smart key fob is a beacon itself, as it works with Bluetooth Smart (aka Bluetooth Low Energy). It is paired with Volkswagen’s mobile app, “Volkswagenim” (My Volkswagen).
The key fob works for 3 main purposes. Once the customer is done pairing the key fob with the app, they can locate their phone nearby by tapping twice on the key fob and hear a beeping sound coming from their phone. They can do the exact opposite and locate the key fob - hence the keys to their car - through the app. It works as a Bluetooth selfie shutter, working like a very long selfie stick by having almost 50 meters of range.
The key fob is unique in a way that it includes Google’s Physical Web functionalities. In fact, it is one of the first major Physical Web products on the market.
