So I have this question about: "How to easily and safely punch hole into RFID card".

I have this 125khz RFID card and I would like to punch a hole in it so I can have a thin string go through it, making my card to be able to hang from my neck.

Though I have no experience in punching hole to any sort of card, not mentioning an RFID one.

  1. Is it possible to punch a hole through the RFID card and still have it work properly?

  2. How should I punch a hole through the RFID card safely, easily and using some cheap accessible tools (list of alternative ways to punch a hole into RFID card is welcomed)

  3. In the picture below, you can see my RFID card in front of a light source, showing the antenna. On the picture, I put a green circle to the place where I need the hole to be (though I can make the hole a little bit smaller as long as a double-string can pass through). Is that a safe distance? Is the whole too big? Is there a chance that it will break the card?

Note: please make your answers to be understandable for an average person like me (who is not deep into this field yet)

The issue is, I don't know where to post this question. The most suitable forum would be RoboticsBeta but they did not have any tags that would be applicable for me (there was no rfid, rfid-card or even card tags).

Can anyone help me to maybe create the appropriate tags at the RoboticsBeta or redirect me to an appropriate forum?

  • no problem :) included an answer for you to consider – DarkCygnus Sep 25 '18 at 17:47
  • Almost tempted to suggest lifehacks. A badge holder would be the sensible solution, no holes needed – Journeyman Geek Sep 26 '18 at 3:15

Seems that there is an tag on Electrical Engineering SE, so I'd suggest you check the questions asked there to see if yours could fit.

    Seems that OP asked his Q over EE.SE: electronics.stackexchange.com/q/397935/194367 – DarkCygnus Sep 25 '18 at 17:56

    Didn't think that my first post at EE would be so active (614 views in 4 hours). Anyway, thanks for the help. I have also credited you at the post :) – Programer Beginner Sep 25 '18 at 22:38
  • Always a pleasure to help :) as a suggestion (completely unrelated to punching holes), why not use something that could glue or stick to the card, so you don't have to punch it? Imagine something like a paper clip or fastener that clamps to your card. That way you won't have to punch it ;) – DarkCygnus Sep 25 '18 at 22:41
  • 1. Had already a template cover (to be stick on the card) with the holes already made | 2. the glue is not super reliable (and using excessive glue will damage the template cover or will create a bulk) | 3. Visually, I liked the card with the holes more :D – Programer Beginner Sep 25 '18 at 22:45
