Possibilities with the Magic Ring

Alright, thank you for providing that resource. It was very helpful, and the formatting was great. So even though the Mifare is HF it can’t transmit NFC information?

Also I don’t think I’ll be able to access an android, it seems everyone I know uses an iPhone :(.

The answer to this is simply that all passive transponders, regardless of frequency, are RFID transponders… but NFC is a narrow set of standards laid on top of RFID. That means that all NFC “chips” or transponders are really RFID transponders that simply comply to the NFC standard, but obviously not all RFID transponders comply NFC standards. The Mifare chips are 13.56MHz like all (so far) defined NFC chip “types”, but it does not comply with the NFC standard so it is not considered an “NFC chip”, if that makes sense.

However, because people love to complicate things, NXP the company that makes the Mifare chips, also makes NFC reader chips. Many of those chips are included in phones, mostly Android phones. Because NXP makes the reader chips, and the Mifare chips, they created a pseudo-standard so that Android phones with NFC reader chips from NXP can also treat Mifare chips as “NFC”, meaning you can read the contents using apps like TagInfo and also write NFC data to them using apps like TagWriter… but still the Mifare chip is not NFC compliant so they are still unreadable by iPhones and Android phones with NFC reader chips from other companies like Broadcom etc.

Ah thank you that clears everything up, very complicated haha. If I can’t find an android what is the alternative or do I just have to gamble and hope that my uni card is HF and entrance key is LF for the mifare and T5577 respectively?

If you want to play in the RFID space at all then I would suggest picking up a proxmark3 … It is the defacto standard tool to investigate and research RFID transponders and readers. Using that tool you can easily figure out what chip is used in your uni card

Yeah that was the plan. However, as I am in the UK shipping is incredibly expensive so if I am going to order it, I would want to order the ring at the same time to avoid two 30$ hits :’(.

Understandable. Maybe head to a phone shop to try out an Android phone and get the TagInfo app set up on it? I don’t know if you can do that in the UK but here in the US the demo phones are pretty much wide open and I just attached the Wi-Fi to my own phone hotspot to load apps and things.

I’m not too sure, I’ll have to give it a shot. Thank you so much for all your help and quick responses!

Where in the UK are you? There might be someone local who could help. Equally you might want to check @KaiCastledine ksec.co.uk as they are the UK distributor for dangerous things.

Im in the South East. I had a look on their site but couldn’t see the rings and the promark3 ‘full kit’ was 500 pounds… I assume it isnt the same promark3 as on dangerous things.

Is there any visible branding on your uni access card or readers.
Can you post pictures of them.

Maybe for an idea video, physically draw an umbrella diagram

Just a thought, I know that would make things click for me


There’s the proxmark 3 rdv4, and the proxmark 3 easy, which is like 79$,
You loose a self contained power source, and ability to swap antennas (the lf coil is kinda nice for some implants)

The 80$ one works because it’s what I have :sunglasses:

This reminds me I kinda wanna design a 3D printable enclosure for an easy, that holds a battery and some kind of raspberry pi

The easy is definitely on the ksec website. They don’t sell the rings though.

South East should have other people on here.

Hi sorry I can’t reply directly on the forum because it says I have replied too many times today and need to wait 18 hours D:.

All branding is for the uni… The only thing I can see is a DHL number but i think thats still for the uni. Only other feature is a magstripe on the back and its white. Meanwhile the key is red key identical to the bottom left one in this picture.
However it has a 6 digit number on the side without the circle.

Upgraded your user level and moved your DM to this thread :arrow_heading_up:

Hmmm…still not super clear.

Photos of a reader or readers if there are different types might be more useful.

I have ordered a proxmark3 from the uk retailer and will get back to you in a few days! Thanks everyone :slight_smile:


Be prepared and warned, the proxmark can be fickle to get started

I would have been lost if not for some of the proxmark gurus on here,

Works decently well when the setup, and implants take a fair about is trial and error to find the exact right spot on the proxmark,

This isn’t a discouragement, just don’t expect to be running in 5 minutes

Correct, we have the three versions available currently.
