Description
Thanks to the digital key tag with an individual QR code, the owner of the keys can be contacted anonymously—without revealing any personal contact information. This enhances security and ensures that the owner's data remains private.
The anonymous and GDPR-compliant location sharing feature helps coordinate a suitable handover location. The finder can share their current mobile location with the key owner, who can then view the spot using Google Maps.
Especially in cases where house keys are lost, quick contact is essential. Unlike traditional key services, the owner can be reached immediately via smartphone. Often, the key handover can be arranged on the spot and completed within minutes.
How it works:
- Someone finds the lost keys and scans the QR code.
- The key owner receives an automatic scan notification via email, letting them know someone has found the keys.
- The finder can enter their name, callback number and/or email, and a short message using a contact form.
- This information is immediately sent to the key owner via email (the finder's details are not disclosed).
- The key owner can then contact the finder to agree on a handover location (e.g., checkout counter at a supermarket).
- Optionally, the finder can share their live location via email in a privacy-compliant way.
- The owner retrieves the keys at the agreed meeting point—usually within a short time.
IMPORTANT: An active internet connection is required to access the data and contact information.

How can I activate my key tag?
The key tag is activated upon first scan. During activation, you can create a free user account or log in with your existing one. You will then be able to enter your personal contact details, which are used solely to forward messages from finders to the key owner.
What happens when someone finds my key tag?
The finder can scan the QR Code on the key chain and leave a message to the key owner.
An automated scan alert will be sent to the key owner without any notice to the finder.
Who has access to my data?
Anyone who scans the QR code with their smartphone can use the web app to fill out and submit an anonymous contact form. However, the finder never sees the key owner's contact details.
Are there any extra or recurring costs?
No, purchasing the digital key tag does not incur any additional costs or subscription fees. The validity period is 5 years. After that, it can be extended for a fee.
