With ekey, you simply open your front door with your finger and your smart home starts right at the door. The proven convenience of keyless access is enhanced by smart applications that are administered via the ekey bionyx app. This gives you an overview of all access points, users and devices, and allows you to administer and flexibly expand your system at any time. The most important functions at a glance: • Easy remote opening: Never wait again to let your trusted craftsman into the house, for example. You can open the door from anywhere - whether from the office, on the go, or on vacation. • Automatic push notifications: No more uncertainty - you can receive automatically generated messages on your smartphone as soon as someone opens your door with the fingerprint scanner. This lets you know, for example, when your child has made it home safely from school. • Practical virtual assistant: Connect your ekey fingerprint scanner to Amazon’s virtual assistant Alexa and open the door simply by voice command, e.g. when you are busy in the kitchen but guests are already at the door. More smart home connections will follow. Your advantages: • Maximum security: Only authorized persons can open the door. An ekey fingerprint scanner is 1,000 times more secure than the four-digit numerical code of an ATM card. • Clear access log: All accesses of the past 30 days can be viewed. • Flexibly expandable system: You do not have to decide in advance what scope your access control system should have. Functions, users and devices can be added at a later date. • Continuous updates: You always have the latest software and benefit from additional functions and ongoing developments.
