New RFIDfriend Tags in Coin holder

I followed the Idea from Gambius to buy coin holders and inserted a magnet and a TAG from RFIDfriend. But I noticed, the TAGs have a new design. When I put a magnet in the center, the TAG does not work anymore, or only when the TAG is not placed in the center of the Toniebox.

Is this from the new design of the TAGs, where the center of the TAG is not empty anymore?



The tags actually also work if they are centered on the box, but the tag must be on the upper side of the capsule.

Well, not shure what is different in my Case. For me its like this:

Without the Magnet the Tag works flawless. (the Tag is always on the upper site) only if i press it down hard, it stops working.

With the magnet, the TAG does nod work in the cernter anymore. Only if i put 2 Layers of between it works again. one Layer is not enough.

Its not so important for my, as the TAGs work fine without a Magnet, but still interesting.




The Tags RFIDfriend is selling at the moment have a diameter of 38mm. These have a larger Antenna in comparrisson to the 30mm tags. This way the magnet is not influencing the signal pathway and the tags are readable by the Toniebox although the coincase has a magnet playced inside and is palced directly in the middle of the Box.

You can find his tags at http://RFIDfriend.com

I figured that if I put the magnet on the edge of the case it works fine mith the RFIDfried Tags i got. (30 mm) only if its placed in the center it blocks the signal from the antenna too much.

But if there was a saller who sold Tags like robert posted, that would be cool. With these you can just drill a small hole and put the Tag in much smaller Figures:

Not sure if this is the right thread but I didn’t think my question warrants a new thread and this one seems to be the most fitting.

I’ve created a couple of travel tonies but I probably bought magnets that were too strong. Once I put them in the coin holder it didn’t play anymore, when it lay centered an the box. When I moved it an inch in any direction it worked again.

So, what magnets are you guys using that seem to work fine?

Did you try to put the Magnets on the edge of the case instead of the center? This way it works for me. I Bought some noname magnets from aliexpress.

Getting it to work isn’t the problem. Putting them in the middle and adding a spacer between the magnet and the NFC tag does the trick, but then the coin capsule is stuffed VERY full. So I’d like to use different magnets for future travel tonies that hopefully interfere less with the tag’s antenna :slight_smile:

So which ones did you buy that you would not recommend?

hi @marco79cgn, i have just built tags with the following components that work perfectly. maybe this will help you.

  • Printable stickers with a diameter of 37mm
  • Coin Cases with a diameter of 38mm on the inside
  • Spacer with a diameter of 38mm: Amazon-Link
  • Magnet that fits perfectly in the hole of the spacer: Amazon-Link

I still owe you a reply :slight_smile:
These are the ones that messed with the tag’s antenna: Scheibenmagnet 22x1 mm Neodym | MTS Magnete - Der Magnetspezialist

Recently I ordered these and so far they work just fine: Scheibenmagnet 10x1 mm Neodym | MTS Magnete - Der Magnetspezialist
They’re are not as strong and not as large as the other ones but still strong enough to keep the travel tonie on the box.

Thanks @roadrunnr & @deckard

In the meantime I already ordered these magnets

together with these coin holders

and these inlays here

Everything works and fits perfectly fine. :slight_smile:

And that’s all that counts :slight_smile:

Do The coin cases you ordered fit good enough and do they stay closed? I Ordered several Cases in the past (at amazon), but they didnt stay closed.

Yes, they do. Make sure you get exactly this combination, since the placeholders, magnets and coin cases have to fit with each other.
