Positiv
Ich habe meinen Geldbeutel direkt verloren und durch die Karte habe ich eine Nachricht bekommen, dass er gefunden wurde und ich konnte den direkt abholen.

Nun ich hatte noch keinen Notfall oder Kontakt über meinen Kleber... Aber beim testen hatte es mich überzeugt dass es gut ist.

Erste Lieferung leider abhanden gekommen
Die erste Lieferung ist leider warum auch immer seitens Deutsche Post nicht in meinem Briefkasten gelandet so fern verschwunden. Kontakt ging problemlos und Ersatzlieferung wurde prompt an mich versendet und war auch fix da. Die Einrichtung ging schnell und einfach. Alles supi :-). Bin gespannt auf die Praxis.

Schnell geliefert, top Kundenservice
Habe Aufgrund eines Angebots gleich drei Artikel hier gekauft. (fürs Auto, Schlüsselanhänger und Geldbeutel) Da ich ausversehen einen falschen Artikel bestellt hatte habe ich den Kundenservice kontaktiert und dort wurde problemlos alles geändert. Lieferung ging am gleichen Tag raus und war zwei Tage später im Briefkasten. Einrichtung und Anmeldung lief ohne Probleme. Kann ich definitiv weiter empfehlen..

You decide: you can set up an open digital profile with the info you want to show, or use only anonymous contact via forwarding — the card itself never shows any personal data.
RFID blockers specifically protect against unauthorized contactless reading (13.56 MHz) at close range — a real but, in everyday life, rare risk. For most customers, the bigger everyday benefit of our card is the second function: the anonymous QR contact option if your wallet gets lost.
The card actively generates a jamming signal on 13.56 MHz — the frequency used by contactless credit and ID cards. Placed between your cards, it overrides the read attempt within a radius of about 3 cm on each side.
A free sleeve usually only protects the one card inside it — all your other cards remain unprotected, and you have to insert and remove each card individually. Our card protects all surrounding cards at once and adds the QR contact function for when your wallet is lost.
No, our card is designed for cards in your wallet. For car keys with keyless-go, there are dedicated protective pouches for the key fob — a different use case.
Just scan the QR code on the card. You'll go straight to an anonymous contact form and can send the owner a message — no app needed.
No, scanning works directly in the browser — handy if someone wants to contact you directly without installing anything first.
No, the basic function (anonymous contact forwarding + open digital profile) is permanently included in the purchase price. Extra channels like WhatsApp or SMS can be added optionally.
