NFC tags are the link between your physical keys and Log+Key. This page covers how to order tags, how a newly delivered tag finds its way into your system and what to look out for on the first scan.
Who supplies tags
You obtain tags exclusively from Log+Key. Your own tags from retail are not permitted — even if they were technically compatible. The reason is consistency: every delivered tag is pre-registered in the database, carries a unique URL and can be bound to your organisation. This pre-registration only works with tags from our supply chain.
How to order
Order tags directly from your contact person — Chiara, Philip or Dom, depending on who looks after you. If you don’t have a fixed contact yet, write to hallo@log-key.de. There is no self-service ordering in the product today.
The list price for a printed tag is €2.50. Discounts are possible for larger quantities — the specific terms come with the quote.
How quickly the tags reach you depends heavily on the quantity and our supplier’s current print batch. Small re-orders from our stock often ship within a few days; larger print runs take longer. We give you a firm delivery date with the order confirmation.
What you receive after shipping
You receive your tags numbered and with the URL stored on the tag. Every tag carries two identifiers:
- the hardware ID — factory-set and immutable, visible on the tag page in Log+Key
- the URL stored on it,
https://logkey.app/tag/<hardware ID>, which the smartphone opens on a scan
At this point the tags already exist in the Log+Key database but are not yet assigned to any organisation. We call this the “fresh” state. As soon as you open a fresh tag for the first time, it appears in your tag list with the status Free.
First scan: activating the tag
Scan the tag with your smartphone — or open its URL in the browser. After signing in to Log+Key you see the tag page: the status Free, the hardware ID and two buttons.
- Link object opens the Link tag to object dialog. There you select an existing object and confirm with Assign — or you create a new object directly via Create and link new object; the tag is then already filled in on the form. Both are described in Link an object to an NFC tag and Create your first object.
- Link user turns the tag into a person’s login tag — their key for signing in at the terminal, see Adding users.
With this first link the tag is permanently bound to your organisation. This binding is deliberately irreversible — it prevents a tag from ending up in someone else’s hands and overwriting data there. Within your organisation the tag stays flexible: you can remove the link at any time and reassign it.
A tag that is already linked opens the object page directly on a scan.
Notes on scanning with a smartphone
NFC on a smartphone works for Log+Key via native URL resolution. In other words: scan a tag and the phone opens the URL — just like with any other NFC tag containing a URL. You don’t need a separate app for this: on a smartphone Log+Key shows the same pages as in the browser on a computer, in a view adapted to the screen.
One exception: in inventory mode, Log+Key uses the experimental Web NFC API, which today is only available in Google Chrome on Android. There you can scan several tags in a row without a URL opening each time.
On iOS and in other browsers, native URL resolution remains the standard route.
If a tag doesn’t work
Defective tags are rare — we haven’t needed a formal process for them so far. If one does turn up, contact your contact person or hallo@log-key.de with the tag number and a short description. We’ll send a replacement.
Officially we ask you to return the defective tag to us. With regular customers we usually waive this — we trust that it was as described.
Two quick checks are worth doing first:
- Is NFC enabled on the phone? Check the settings.
- Direct contact with the tag? Some phone cases or metal fobs weaken the NFC field. Hold tag and phone directly together for a moment, without anything in between.
